CALIBRATION AND MAINTENANCE
There are no internal user adjustments. Calibration is performed
without opening the instrument.
All Calibrations
To enable calibration mode, open the battery compartment, remove
the anti-tamper label, and insert a 2.54 mm
(0.1”) pitch programming
shunt. Manipulation of the shunt is easier with needle nose pliers. The
instrument will display ‘CAL’ and installed options.
View Inside Battery Compartment
Known calibration constants can be re-entered directly without using
other equipment. This is useful in case old calibration constants are to
be put back.
Before commencing calibration:
•
Clean all connectors very carefully.
•
Ensure that all devices have been at a stable room
temperature for over an hour, and that the light source is fully
warmed up at the wavelength to be calibrated.
•
Ensure that all installed batteries are in good working
condition.
•
When calibration is complete, remove the calibration shunt,
and place an anti-tamper label over the aperture in the
battery compartment.
•
Do not forget to update your calibration records, and
schedule the next calibration service.
System Rollback (version 5.0 and above)
In the event of wrong calibration constants being entered and stored,
or the instrument becoming otherwise corrupted, all factory settings
can be restored. To restore all factory settings, first enter ‘CAL’ mode
then press and hold [MR] for 3 seconds.
Power Meter calibration:
Calibration is a transfer process. It is performed by setting up a single
mode laser source at a stable, but non-critical power level between -
10 and -30 dBm, and adjusting the meter reading to the same value
as that shown by a reference meter.
