Chapter 2 Measurement Preparations
The instrument operates on battery power or AC
through the adapter. When using the AC adapter
and batteries together, AC adapter power is
employed.
When powering the instrument using the batteries,
the operating time is as follows:
About five hours when indications are shown on
the monitoring screen [MONI]
(Ambient temperature: 23°C, reference value)
The operating time varies depending on the ambi-
ent temperature and type of batteries used.
2.2 Installing the Batteries
Do not mix old and new batteries, or different
types of batteries. Also, be careful to observe
battery polarity during installation. Otherwise,
poor performance or damage from battery
leakage could result.
• Do not use other than the specified type of bat-
teries (LR6 alkaline batteries). Using manganese
batteries will result in a shorter operating time
than when using alkaline batteries.
• When measurement data must be recorded, use
the AC adapter.
• The indicator appears when battery voltage
becomes low. Replace the batteries as soon as
possible.
• After use, always turn OFF the power.
• To replace the batteries, see 6.1, "Battery
Replacement" (page 103).
