•
Place the three position range switch in the 20 mW/cm2 position. Place the READ/HOLD switch
in the READ position.
•
Turn the unit on by placing the OFF-ON/TEST switch in the ON/TEST position.
Note: For the first one second of operation, the entire display will be turned on demonstrating that all
segments, decimal points and colon of the display are functioning properly. The readout you should
see for that one second period, if everything is functioning correctly, is -18:8.8. If any one of the
segments, decimals or colon is not turned on during that time, refer to the Troubleshooting tips in this
manual.
After the one second test mode is completed, the circuit will automatically revert to the normal read
condition.
•
At that time, the meter should be zeroed to assure the best accuracy. This is done by first
covering the sensor so that no UV light strikes the sensor window. (Generally, turning the sensor
upside down on a bench will suffice.) The range switch is then placed in the 200 µW/cm
2
position
and the zero adjustment trimpot for a display reading of 00.0 µW/cm
2
.
•
After setting the zero, ultraviolet readings may be taken by placing the sensor in the UV
environment. The resultant intensities will be shown on the display.
