RECORDING, STORING AND RECALLING READINGS AND CLEARING MEMORY
To record data at a particular location, press [
◄►
], then [-/+] to select
the location, [Set] and [M+]. This will overwrite any previous data
stored there.
Recalling stored data
Note:
return to ‘Menu’
to recall data recorded in Autotest mode. Data
recorded in Power meter, Light source and ORL modes can be
accessed in one of these modes or via ‘Menu’.
To recall data recorded in all modes, press [MR] and [-/+] to specify
location.
For data recorded in Autotest, press [-/+] to view measurements at all
source wavelengths.
For each wavelength, to step through all available Two Way Loss and
ORL Autotest measurements, select [MR], [-/+] and then press [
◄►
]
repeatedly.
To display recalled value in dB R, press [Abs/Rel].
Over-writing one stored data/result
This is often required when re-testing one item.
i.
Note your current memory location: Press [MR] to see the number
at the top right corner of the display.
ii.
Go to or select the memory location for re-test (memory over-
write): Press [-/+] to change to that location, and press [Set].
iii.
Do the retest and save the retest data/result: press [M+] to
overwrite the memory location selected above with the retest data.
iv.
Go back to the current location: Press [-/+] to change back to the
current location noted in step i, and press [Set].
v.
Continue with testing.
Clearing memory
A full memory is indicated by activated buzzer.
To clear all stored data, press [MR] and [Exit] simultaneously for 3
seconds. The buzzer will sound and display will show

Memory capacity (in Autotest)
Working memory capacity is determined by the configuration of your
instruments. The capacity of one instrument is illustrated in Table 1,
the combined capacity of the instrument pair is ‘No of readings’ x 2:
