no hazard to the operator. Aeroflex reserves the right to amend the above information in the

BATTERY REPLACEMENT
The instrument contains a real-time clock which is powered by a lithium battery when the
normal power is removed. Although battery life can extend to five years, this will depend on
conditions of use, e.g. battery life is reduced as the temperature is increased. To avoid loss of
data it is recommended that the battery is replaced every two years.
Replace the battery as follows:
(1)
Ensure that the instrument is switched on; this will provide power for the
non-volatile memory while the battery is replaced. If this is not possible, the
clock will continue to run for approximately 30 seconds, whilst the replacement is
made.
(2)
Using a coin or suitable tool, unscrew the battery compartment cover at the rear of
the instrument.
(3)
Remove the battery, noting its orientation. Insert the replacement, then replace
the battery compartment cover.
The replacement battery should be SAFT L56 or equivalent. This is a lithium 3.5 V type,
rated at 1800 mAh, size AA. If a lithium battery is unobtainable an alkaline battery can be used
but it will have a shorter life. A suitable battery can be obtained from Aeroflex.
CLEANING
Before commencing any cleaning, switch off the instrument and disconnect it from the
supply. The exterior surface of the case may be cleaned using a soft cloth moistened in water.
Do not use aerosol or liquid solvent cleaners.
PUTTING INTO STORAGE
If the instrument is to be put into storage, ensure that the following conditions are
maintained:
Temperature range:
−
