5.10. Battery change indicator
Batteries almost discharged
When the batteries are approximately 75% used, the
battery symbol will flash a few times as soon as the
instrument is switched on (if at least one of the batteries
still has some charge). Although the instrument will con-
tinue to measure reliably, you should obtain replacement
batteries.
Batteries discharged – replacements required
When the batteries are discharged, the battery symbol
will appear, unblinking, as soon as the instrument is
switched on. You cannot take any more measurements
and must replace the batteries.
1. Open the battery compartment on the bottom of the
instrument.
2. Replace all of the batteries at the same time – ensure
they are correctly connected, as shown on the sym-
bols in the compartment.
3. The memory retains all values although date and time
must be reset – the year number will flash automatical-
ly after the batteries are replaced.
4. To set date and time, follow the procedure described
in Section 4.3.
Note:
Use four new AA 1.5 V batteries. Do not use batteries
beyond their expiration date. If the monitor is not going
to be used for a prolonged period, the batteries should
be removed.
