7. Product description

The UV meter allows precise measurement of radiant power of invisible ultraviolet radiation (UVA and UVB). The UV radiationmeasurementndsitsapplicationinindustrialsectorssuchasweldingwork(arc),electronics,photochemi- cal processes or printing applications. The device can also be used e.g. for laboratory tasks, in agriculture and horticulture. This includes weather and growth studies as well as UV sterilisation, etc. In the private sector, the meter can be used to easily and precisely determine the radiant power of solariums or the sun, etc.

The meter can be used as a mobile device with a battery or a rechargeable battery. During stationary operation or long-term measurements, an optional power supply can be connected. When connecting a power supply, the connection between the battery and the meter is automatically inter- rupted. So the battery does not need to be removed for power supply operation. a) Inserting or changing the battery

• Beforerstuseorwhenthebatterychangesymbolappearsintheupperlefthandcornerofthedisplay,anew,fully charged battery must be inserted.

• When changing the battery, make sure that the meter is turned off.

• Use a suitable Phillips screwdriver to unscrew the screw on the battery compartment (13).

• Slide the battery compartment cover off the device in the direction of the arrow.

• Connect a new battery to the battery clip, observing the correct polarity. Insert the battery into the meter. Make sure that the connection cables are not pinched.

• Close the battery compartment in reverse order and screw it back in carefully.

• 21 b) Connect power supply (optional)

• The power supply must provide a stabilised voltage of 9 V/DC and a current of at least 300 mA.

• TheDCbarrelplugmusthavethefollowingspecications: - Outer diameter 5.5 mm - Inner diameter 2.5 mm - Polarity: Inside positive pole, outside negative pole.

• Toconnectthepowersupply,openthesidecover(12).Useasmallat-headscrewdriverforthis purpose, for example.

• Insert the DC barrel plug of the power supply into the “DC IN” socket.

• Connect the mains adapter to a common household wall socket. The wall socket must be nearby and easily accessible. After completion of the measurement, disconnect the power supply from the meter and close the cover.

a) Connecting the sensor The sensor is a high-precision component that wears out due to excessive humidity and thus becomes inaccurate. Therefore, the sensor head should always be stored in as dry an environment as possible. It is also recommended that the sensor be stored in an airtight foil bag. Put a packet of dry granules in the foil bag. Replace or regenerate these dry granules on a regular basis to ensure a dry storage environment. Remove the sensor from the bag for measurement purposes only. This measure extends the ser- vice life of the UV sensor. Otherwise, the sensitivity decreases and the recalibration interval is shortened. When connecting the sensor, make sure that the meter is turned off. Insertthesensorconnectionplug(14)intothesensorsocket(1)onthemeter,observingthecorrectpolarity.Theat side of the plug should thus face the back of the meter. b) Switching the measuring instrument on and off

• Use the “POWER” on/off button (4) to turn the meter on and off. Each time you press the button, the device turns on and off.

• The meter will turn on with a short beep and display the start screen with all display segments for approx. 3 seconds.

• After the display test is completed, the display shows the current measured value.

• Press the on/off button to turn off the device. The device turns off with a long beep.22

10. Taking measurements

In order to obtain precise measured values, the measuring instrument must be adjusted to the ambient temperature. Allow the device to adjust to the ambient temperature after relocation. Lengthy UV measurements on light sources with high temperatures can cause self-heating of the meter and thus a faulty measurement if the measuring distance is small. In order to obtain precise measured values, remember the following rule of thumb: The higher the temperature, the greater the measuring distance and the shorter the measuring time. a) Performing the UV measurement To perform the UV measurement, proceed as follows: - Put the meter into operation. After turning on, the meter is always in the large measurement range of 20 mW/cm². This range is intended for measurements from 2 to 20 mW/cm². - Remove the sensor protective cap from the sensor. - Align the sensor surface as perpendicular as possible to the light source. - The measured value appears on the display. - Change the measurement range to perform measurements less than 2 mW/cm². To do this, press the button with the inscription “2” (5). To switch the measurement range, press the respective range button “2” (5) or “20” (6). - If “- - - -” appears on the display, the measurement range has been exceeded. Switch to a larger measurement range if possible. - Turn off the meter when the measurement is completed. Replace the sensor protective cap. b) Zero adjustment To achieve high accuracy, the meter can perform zero adjustment. Zero adjustment is only possible and useful if the displayshowsameasuredvalueof≤0.1mW/cm². To perform zero adjustment, proceed as follows: - Cover the sensor head with the lightproof sensor cover (17). - Press and hold down the “2 mW/cm²” range button (5) for approx. 2 seconds. Zero adjustment is signalled with a beep. The measured value on the display is reset to zero. c) Holding the measured value (“HOLD”) The current measured value can be held to obtain a longer reading time. To hold the measured value, press the “HOLD” button. The keystroke is signalled with a beep. The measured value and the “HOLD” symbol appear on the display. To disable the function, press the “HOLD” button again. “HOLD” disappears from the display.23 d) Recording the measured value peaks (“REC”) The “REC” function allows the highest and lowest measured values to be recorded and read out from the device in measurement operation. The meter cannot be turned off if the “REC” function is enabled. In this case, the automatic power-off is also disabled.

• To enable the recording function “REC”, press the “REC” button (7).

• The keystroke is signalled with a beep. The current measured value and the “REC” symbol appear on the display. In the background, the lowest (MIN) and the highest (MAX) measured values are automatically stored.

• To read out the highest measured value on the display, press the “REC” button again. The display shows “REC MAX” together with the highest stored value.

• To read out the lowest measured value on the display, press the “REC” button again. The display shows “REC MIN” together with the lowest stored value.

• Pressing the “REC” button toggles between the MIN-MAX display.

• To start a new peak value measurement, you can use the “HOLD” button to delete the MIN or MAX values stored. The display will then show “REC” and the peak value measurement will start again for the selected function (MIN or MAX).

• To disable the function, press and hold the “REC” button for approx. two seconds. The memory function is disabled with a beep. The measured values will then be deleted. e) Automatic shut-off feature The meter will power off automatically after an operating time of approx. 10 minutes. This function saves battery power and extends the service life. The automatic shut-off function can be disabled to allow longer measurements to be carried out. Automatic power-off is disabled when the “REC” function is turned on. In this case, the meter will not power off automatically.24
