CALIBRATION AND MAINTENANCE
Light Source Calibration
The emitter power level can be re-calibrated, and the current checked.
Required are reference power meter with appropriate calibrated
wavelengths, single mode and multimode test leads, an anti-tamper
label. Check the calibration certificates on your reference equipment
to ensure current validity.
CAUTION! Use of controls or adjustments or performance of
procedures other than those specified herein may result in hazardous
radiation exposure.
Calibrate the source at the selected wavelengths as follows:
•
Inserting the
2.54 mm (0.1”) pitch programming shunt across
pins will put the instrument into calibration mode. It will
display ‘CAL’.
•
Press [
λ
] to set the wavelength to be calibrated. Measure
light source power using the reference meter.
•
Press [
λ
] to display DAC values from 0 to 1023 and
emitter current.
•
Set the emitter power to the required level by pressing
[MOD] to reduce and [LEVEL] to increase output.
•
Press [
λ
] to save new value and to exit.
•
To return to factory default setting, press [
λ
].
•
Repeat the above process for any additional wavelengths if
required.
Opening the Instrument:
CAUTION!
•
Do not open unless warranty has expired and you are
authorised to do so. Opening the unit will invalidate any
warranty claim.
•
This unit contains static sensitive devices. Anti-static
handling procedures should be observed at all times when
handling internal circuits.
•
There are no internal user adjustments. All calibration is
performed without opening the instrument. The optical
sensor / connector assembly is not user serviceable.
Procedure:
•
Open battery compartment and remove the batteries. Pull
open the optical connector cover.
•
Place the instrument face down on a soft mat, remove belt
clip and undo the screws in the rear housing. The instrument
can now be gently pulled apart.
•
Further disassembly from this stage should be easily
apparent to a technician.
•
Re-assembly is the reverse of the previous procedure.
