We shall not be held liable for material or personal damage resulting from improper handling or non-compliance with the safety provisions. In such cases, any warranty claims are ruled out.

The digital thermometer 306 left our factory in perfectly safe technical condition. To maintain this condition and to ensure safe operation, the user must comply with the safety provisions and warning instructions ("Attention" and "Note!") contained in these Operating Instructions. The following symbols must be observed:

= Read the Operating Instructions

• Measuring devices and accessories are not toys, and thus must be kept away from children!

• When used in industrial plants, the Provisions for the Prevention of Accidents of the Association of Industrial Employers' Liability Insurance Associations for Electrical Installations and Equipment must be complied with.

• In schools, training centres, hobby and do-it-yourself workshops, operation of timer switches must be supervised by responsible, well-trained staff.

• When handling the thermometer, make sure that the measurement fluids are de-energized! Particular caution is required when handling voltages exceeding 25 V AC or 35 V DC. When touching live electrical conductors, you may suffer a potentially fatal electric shock even at such voltages!

• Before any measurement, check your measuring device or your temperature sensors for damage.

• The voltage between measuring device and ground must never exceed 24 VACrms or 60 VDC.

• Do not operate the measuring device in rooms or in adverse ambient conditions which involve (or might involve) inflammable gases, vapours or dust. For your own safety, it is essential to prevent the measuring device or the measuring lines from getting damp or wet. Operation should be avoided in the immediate vicinity of

a) powerful magnetic fields (loudspeakers, magnets)

b) electromagnetic fields (transformers, motors, coils, relays, contactors, solenoids etc.)

c) electrostatic fields (charge/discharge)

d) Transmission aerials or RF generators

• Do not use the digital thermometer just before, during or just after a thunderstorm (lightning! / high-energy overvoltages!). Make sure that your hands, shoes, garments, the floor, the measuring device, the measuring lines, circuits and circuitry components are dry.

• If safe operation can no longer be reasonably assumed, the unit must be decommissioned and protected against involuntary operation. Safe operation cannot be reasonably assumed if

• the unit shows visual traces of damage.

• the unit no longer functions and
• after extended storage under unfavourable conditions or

• after severe strain during transit.

• Never switch on the measuring device immediately after having taken it from a cold into a warm room. Under certain circumstances, the condensate thus developed may destroy the device. Allow the device to adjust to room temperature before switching on.

Presentation, system prerequisite(s)

This digital thermometer 306 with PC connection has several smart features to supplement many measurements:

The "MAX MIN" function, for example, enables determination and recording of the highest or lowest measured value. The "HOLD" function serves to record fast changing measured values (for test records). The "TIME" push-button helps you interrogate the (preset) current time-of-day (with date). The "REC" push-button starts pickup of measured values. The ^ C / ^ push-button offers the choice between two units: the "British" in Fahrenheit, and the "metric" in Centigrade. If you actuate the "MAX MIN" push-button while switching on the device, you can access the setup menu; but this will be described in more detail later on.

The measuring range extends from -200^ to +1370^ or from -328^ to +2498^ . However, the temperature range of the enclosed sensors is limited to -50^ to +200^ .

A bidirectional connection to the PC is established via the (serial) interface cable supplied with the device. Installation of the appropriate software on the PC enables the digital thermometer to communicate with the PC.

The digital thermometer 306 can be used for a wide range of hobby applications and in professional or school environments.

The following prerequisites for installation and operation of the software must be fulfilled:

Min. 486 DX2/100 with 16 MB RAM or faster/bigger

Min. Windows '95 or '98 or NT 4.0 or a more recent version

Resolution min. 800 × 600 , and finally 5 MB of free HD space.

Handling, start-up

A Battery installation - replacement

To enable your measuring device to work properly, it must be equipped with a 9 V monobloc battery. If the battery replacement symbol on top left appears in the display, you must replace the battery. To this effect, proceed as follows:

• Disconnect your measuring device from the measuring circuit and from the PC,
• remove the temperature sensors from the measuring device,
• switch it off and
• carefully push the battery compartment cover off in the direction of the arrow.
• Disconnect the discharged battery from the terminal clip and

• replace the battery with a new one of the same type.

• After replacing the battery, place the connected battery into the battery compartment and

• close it carefully again.
• When closing the battery compartment, make sure not to squash the line of the terminal clip (red/black).

Never operate the measuring device while it is opened.

Do not leave discharged batteries in the measuring device, as even leakage-proof batteries might corrode; thus chemicals might be released which are harmful to health or might damage the battery compartment.

Discharged batteries must be considered as toxic waste and thus have to be disposed of in an environmentally responsible fashion. Specific collectors are provided to this effect at special retailers or in recycling centres.

B Connection of the measuring lines

Make sure only to use the temperature sensors specified to this effect for your measurements (in this case: K type). Before connecting lines, check plugs or sensor tips ("beads") for good condition and for flawless insulation (free of damage).

Make sure that only the temperature sensors are exposed to the temperatures to be measured. Make sure to observe the safety provisions and the technical data as regards the service temperature. The max. input quantities must never be exceeded.

C Start-up

C1 Basic setting

The measuring device is switched ON or OFF via the coloured push-button "I". The device can also be switched off via the Auto-Power-Off function. Auto Power Off means: automatic shut-off of the device in the so-called "sleep mode" (standby mode). The device is switched off after approx. 30 min. if no push Buttons are actuated, or the measuring device does not record measured values (REC), the Auto-Power-Off function has not been switched off previously.

To switch off the Auto-Power-Off function, simultaneously actuate the HOLD pushbutton while switching on the thermometer. The symbol "O/ " indicates that the automatic power-off feature has been switched off.

C2 Key assignment

a) MAX MIN for temperature measurement input "T1"

By actuating the push-button "MAX MIN", you get to the maximum and minimum recording. The highest and the lowest temperatures occurring are continuously determined and saved. On each actuation of the push-button, the maximum value "MAX", the minimum value "MIN", or the instantaneous measured value "MAX MIN" (flashing) is displayed alternately. To exit this function, actuate the push-button "MAX MIN" for approx. 2 seconds.

Note!

During max./min. value recording, the unit cannot be changed.

b) TIME for time representation

By actuating the "TIME" push-button (after having set the time-of-day), the current date is indicated with year (center), month, day (bottom left) and time-of-day (hours:minutes, bottom right). Each push-button actuation is confirmed with a short "beep" of the bleeper.

To set the clock, proceed as follows:

Setting the time-of-day is possible by actuating the push-button "MAX MIN" simultaneously while switching on the thermometer. Thus, you get into the setup menu "Set". Now actuate the "CLOCK" push-button (below Time). The display field for date and time-of-day appears; the year is flashing. By actuation of the push Buttons "^" for upwards (= "REC") and "v" (= "°C/°F") for down, the setting can be changed upwards or downwards.

Set the year and subsequently actuate the push-button "TIME" once. Now, the "month" segments are flashing.

Set the current month (e.g. 01 for January) and subsequently actuate the push-button "TIME" once. Then the "day" segments are flashing.

Set the current day (e.g. 08 for the eight day of the month) and subsequently actuate the push-button "TIME" once. Now, the "hour" segments are flashing.

Set the present time in hours (24-hour display) and afterwards press the push-button "TIME" once. The minute segments will now flash.

Now, set the minutes. Then, press the push-button "TIME" once in order to complete the setting of the time. The display will show the memory available (e.g. 16312 for 16312 memory locations) and then it will switch over to the "normal" temperature display.

Your clock is now set exactly.

c) HOLD function

The HOLD function is switched ON or OFF with each (brief) actuation of this pushbutton. HOLD means that the current measured value of T1 is recorded until the Data Hold function is switched off again. While the measured value of T1 is held, the temperature difference T1-T2 and display of temperature T2 continue. Changing over from ^ C to ^ F or vice versa is not possible, neither is activation of the time display nor the function "MAX MIN".

d) Data logger, measured value recording

The REC push-button starts saving the measured values. At intervals of e.g. 5s (adjustable, recording interval), the measured values (T1 and T2) are saved and the time is recorded. The values are stored in a memory location. Then, the values are displayed on the computer in the "data logger" window via the command "Load Data".

To set the recording interval, proceed as follows:

By actuating the "MAX MIN" push-button while switching on the thermometer, you get into the setup menu "Set". Now acknowledge the "HOLD" push-button once. Subsequently, "INT" appears for "interval", as well as a flashing minute display. Now set the desired recording interval in minutes and seconds. Max. 59 minutes and 59 seconds can be set. The minimum value is limited to "00:01" (= 1s). After setting has been performed, actuate the "HOLD" push-button once, to get back to the display of the instantaneously measured temperature.

To delete the memory, switch off the device!

Press and hold the "REC" button and then switch the device back on by pressing the "POWER" button!

If the memory has been deleted successfully this will be indicated in the"CLR" display.

Note!

Each push-button actuation is confirmed with a short "beep" of the bleeper installed.

C3 Socket assignment

The T1 and T2 sockets are so-called unipolar blade-contact bushes. You have to connect the K type temperature sensor to these bushes if you want to perform temperature measurements according to the sensor specifications. Please consider the fact that the blade contacts of the connectors have different widths.

Never try to press mixed-up connectors (+ and -) forcefully into the bushes. This would destroy the bushes beyond repair, and they would have to be replaced.

The "OUTPUT" bush is the serial RS 232 interface in 3.5mm stereo jack format. Assignment has been determined as follows (view of connector):

On the back of the connector, the ground = GND = ground reference (=reference potential) is provided.

In the center of the plug is the contact RX = 5V high input (=data input)

On the front tip, the contact TX = 5V High output is provided (=data output).

Last but not least, the DC 9V bush is provided. A power supply unit with the following output data can be connected to it: 9 V DC voltage, if possible, stabilized with an output current of min. 100mA , a connector OD of 3.5mm and a connector ID of 1.35 mm. The polarity: Minus "-" inside, Plus "+" outside.

D Operating position

Always operate the digital thermometer 306 so that you can read the liquid-crystal display (LCD) or so that the digital display faces upwards.

PC connection, software installation

How to perform a measurement

The temperature measurement range of the digital thermometer ranges from -200^ to +1370^ .

The temperature range of the enclosed sensor ranges from -50^ to max.! 200^ . Do not use the probe delivered with the equipment to measure any temperatures greater than +200^ ( =392^ ).

It must be taken account of the fact that "outside" of the temperature range from +18^ to +28^ (=range of guaranteed measuring accuracy) only the thermo probe may be exposed to the temperature to be measured.

For temperature measurement, proceed as follows:

1. Connect either one or two of the enclosed temperature sensors to the thermometer, as required for your purposes, and switch it on.

Do not connect voltages! This might destroy the device.

1. Hold the temperature sensor(s) (line end(s)) to/in the de-energized measuring fluid (heat sink, etc., but not in caustic or inflammable fluids!).

Notes!

In the small display on the left, the differential temperature of T1 minus (-) the T2 temperature is continuously determined and indicated.

In the small display on the right, the temperature of T2 appears permanently. If one of the temperature sensors is not connected, or even interrupted, "- - - " appears instead of a measured value. In this case, difference determination is not performed / displayed either.

Disposal

If the digital thermometer 306 is not operable or defective beyond repair in spite of correct supply (9 V block battery), it must be disposed of according to the applicable legal requirements.

Troubleshooting

By purchasing the digital thermometer 306, you now have a product designed according to the state of the art.

Nevertheless, problems or trouble are not excluded. Thus, the following text describes the methods you can use to eliminate some of this trouble on your own; please make sure to observe the safety provisions!

Errors Possible cause
no transmission Safe contact of connection line? to PC Software loaded according to instructions? PC interface OK?
No indication when Is the battery discharged? Did the measuring device switch off automatically after being out of operation for 30 minutes?

Maintenance and calibration

You should calibrate the thermometer annually in order to ensure the accuracy of the thermometers for a long period of time.

The adjustable capacitor "CAL" can be used to calibrate the measuring device. Use a Philip's screwdriver of a suitable size. Turn it carefully to the left and to the right during the measurement, until the display shows the exact value of the reference device.

The battery exchange is described under "Handling, commissioning A".

Use a clean, lint-free, antistatic and dry cleaning-cloth to clean the device and the display.

Do not use any carbon-based cleaning agents or gasolines, alcohols or similar fluids for cleaning. These might attack the surface of the unit. Moreover, the vapours are unhealthy and explosive. Do not use any sharp-edged tools, screw-drivers or metal brushes etc. for cleaning either.
