Measuring Power or Loss (EPM-50) 8
4 Measuring Power or Loss
(EPM-50)
Nulling Electrical Offsets
Temperature and humidity variations affect the performance of electronic circuits
and optical detectors. Nulling the electrical offsets eliminates these effects. You r unit
has been designed not to require offset nulling under normal operation, but you
should perform it whenever environmental conditions change significantly or when
measuring very low power values.
Note: Factory-defined values will be reinstated when you turn off the unit.
To perform an offset nulling:
Hold down and a few seconds. The unit
displays NULL while nulling the offsets, then returns to
normal mode.
Note: Keypad is disabled during the operation.
IMPORTANT
If light reaches the detector when nulling offsets, LIGH appears on
the display and the nulling is not performed. You will need to press a
key to return to the previous display.
