6. Battery change indicator
Batteries almost discharged
When the batteries are approximately 75% used, the bat-
tery symbol will flash 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 mea-
sure 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 additional measure-
ments and must replace the batteries.
1. Open the battery compartment at the bottom of the
instrument.
2. Replace all of the batteries at the same time – ensure
they are inserted correctly, as shown on the symbols in
the compartment.
3. The memory retains all values although date and time
must be reset – the year number will flash automati-
cally after batteries are replaced.
4. To set date and time, follow the procedure described in
Section 4.2.
Note:
Use two new, Long-Life 1.5 V AAA 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.
