Intended use This product is intended to be used in the following manner: - Measuring temperatures by optional K-type temperature sensors in a temperature range from –200°C to +1370°C or –328°F to +2498°F. - Max. voltage at the inputs is 60V DC or 24V AC - Use only a 9V block battery for voltage supply - Use only in dry areas 13Applications other than those described above will result in damage to the product that can be dangerous, e.g. a short circuit, fire or an electric shock. The product should not be modified or rebuilt in any way and the housing should not be opened! The safety information must be followed at all times! Safety information Damage caused through non-observance of these operating instructions is not covered by the guaran- tee. We accept no responsibility for any consequen- tial damages that result! An exclamation mark within a triangle indicates important information in the operating instructions. Before operating the product please read the instructions. For safety and licensing reasons (CE) unauthorised rebuilding or modification of the hand thermometer is not permitted. Never exceed the maximum input limits. In commercial facilities, the electrical equipment safety regulations from the German Federation of Institutions (HVBG) are to be observed. Keep away from children. In case of queries that cannot be answered in these operating instructions, please contact a specialist or our customer support service. 14Product description The hand thermometer K101 and K102 are robust and precise devices for the measurement of temperature by optional K-type thermocouples. All commercial K-type thermocouples can be con- nected to the devices via a standard blade terminal. A selection of various thermocouples (temperature sensors) can be found in our catalogue. The K101 comes with one input port for the thermocou- ple and the K102 with two input ports. The maximum temperature range for these devices is –200°C to +1370°C or –328°F to +2498°F, depending upon the respective temperature sensor.

(only K102) Operation Inserting/changing the battery The hand thermometer requires a 9V block battery to operate. When the battery is empty the display "Low Batt" " " (4) will appear in the LCD display. The battery will need to be replaced as a correct display cannot be made when the battery is low. The procedure for changing the battery is as follows: - Disconnect the device from the temperature sensor/s and turn it off. - Open the battery compartment (10) by pushing the battery com- partment cover towards the bottom. - Remove the empty battery and replace it with a new battery. - Replace the battery compartment cover. Do not leave the battery lying around, there is a danger that a child might swallow it. Batteries that have expired or been damaged can cause skin burns. Do not throw batteries into the fire! Environmental notice As the end user you are legally obliged (battery regulations) to return all used batteries (including button cell and lead batteries); disposal in household refuse is forbidden. 17Used batteries can be returned free of charge to our branches or head office in Hirschau or, as always, to your local authority waste management centre (recycling centre) who are obligated to accept the batteries. Make a contribution to protecting the environment! Switching on/off Press the On/Off button (4) to switch the hand thermometer on or off. Connecting the temperature sensors Connect a commercial K-type temperature sensor to the input T1 (1) and T2 (2) (only for K102). If the temperature sensor is defective or not properly connected, "----" will appear in the LCD display. Take note that the maximum input voltage at the input, 60V DC or 24V AC, must not be exceeded! Selecting the temperature unit °C/°F When the hand thermometer is switched on the temperature is shown in degrees Celsius. To change the temperature to degrees Fahrenheit press the °C/°F button (8). To display the temperature back in degrees Celsius press the °C/°F button (8) once again. Data-Hold function The hand thermometer is equipped with a Data-Hold function. This allows the current temperature reading in the display to be "frozen". To freeze the temperature reading press the hold button (6). When activated the Data-Hold function will be indicated in the LCD display with the "hold" symbol " " (1). The hand thermometer continues to

18read the current temperature in the background. To deactivate the Data-Hold function, press the hold button (6) once again – the hold symbol " " (1) will be extinguished. In the LCD display the current temperature will now be displayed. Note: When the Data-Hold function is activated, the Relative and MIN/MAX functions as well as the °C/°F switch are no longer acces- sible. Relative function The hand thermometer is equipped with a Relative function. By pressing the Δ Rel-button (7) the hand thermometer will register the temperature at the pressing of the Δ Rel-button (7). The difference between the temperature readings will be indicated in the LCD dis- play. To deactivate the relative function, press the Δ Rel-button (7) once again. Max/Min function The hand thermometer is equipped with a Max/Min function. This function records the lowest (Min) and the highest (Max) tempera- tures during the measurement. As a result processes can be easily monitored. By pressing the Max/Min button (5) you will reach the Max/Min function. Through repeated pressing of the Max/Min but- ton (5) you can scroll though the various temperatures (Min/Max/Current). When "MAX" (3) is displayed, the highest temperature recorded will be shown, when "MIN" (2) is displayed, the lowest. When "MAX MIN" blinks simultaneously in the LCD display, the current temper- ature will be shown – the maximum and minimum temperature val- ues will however continue to be updated and recorded. To leave the Min/Max function press and hold the Max/Min button for approximately two seconds.

19Deactivating the automatic shut off In order to save the batteries the device is equipped with an auto- matic power off function (automatic shut off). If the device is not operated for more than 30 minutes it will automatically shut off. The automatic shut off is activated when the hand thermometer is switched on. When activated, the automatic shut off is signalled in the LCD display with the automatic power off symbol " ". To deactivate this function switch the hand thermometer off. Press and hold the Hold button (6) while switching the hand thermometer back on. The automatic shut off is now deactivated and the auto- matic power off symbol " " will be extinguished. Calibration The hand thermometer is calibrated in the factory. For precise mea- surements the hand thermometer can be set to the respective tem- perature sensor. Hold the temperature sensor in a container of icy water (0°C). Check the hand thermometer’s display after approxi- mately one minute. If it does not read 0°C it can be correctly set by turning the offset calibration screw (9). For more precise measure- ments the hand thermometer can be set with an optional thermocal- ibrator. Maintenance and cleaning Clean the casing occasionally with a dry cloth. Never use liquids nor cleaning agents. Maintenance or repairs must be carried out by qualified personnel. Remove batteries from the device when it is not to be used for an extended period. 20Disposal Dispose of a defective device according to the current legal regula- tions.
