5.8. 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 continue 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 symbols
in the compartment.
3. The memory retains all values.
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.
