UVP UVX Radiometer - Manual (Page 8)

UVX Radiometer 8
CAUTION
Refer to the Safety Precautions section of this manual before making ultraviolet
measurements with this Radiometer. If all the digits are blank except for the
leading “1” when the sensor has been placed in the UV radiant incident field, an
overrange condition is indicated. This may be corrected by switching to a less
sensitive range or by moving the sensor away from the UV source. If this is
impractical, then the optional 10:1 Attenuator must be used.
If, however, the reading contains less than three significant digits, use a more
sensitive scale or move the sensor closer to the source.
To hold a reading after it has been obtained, change the position of the
HOLD/READ switch to the HOLD position. This will hold the reading until the
switch is returned to the READ position.
In the event the battery voltage falls below that necessary to ensure accurate
operation, “LOBAT” text will be shown on the display on 2014 and newer models,
or a colon (“:”) for 2013 and older models. When this happens, turn off the
Radiometer and replace the battery with a new one.
