the back of the ASTUTE140
®
Meter.
To avoid damage to the ASTUTE140
®
Meter from a potential power surge, always plug
the AC power adapter into the electrical power source prior to connecting it to the
meter. When removing power, disconnect the AC power adapter from the
ASTUTE140
®
Meter prior to unplugging it from the electrical power source.
Installation and Replacement of Batteries
The ASTUTE140
®
Meter is meant to be powered by plugging the AC power adapter into an
electrical power source (See “AC Power Supply” on p. 17).
Power may be supplied for a limited period of time by four AA batteries when an electrical power
source is unavailable (for example, in the event of electricity failure or if the meter must be
operated in a location where there is no electric output). NOTE: If the AC power adapter is in use
and the electrical power fails or the power adapter becomes disconnected, the meter will power
off even if batteries are installed in the ASTUTE140
®
Meter.
When using alkaline or lithium batteries under a temperature operating range of 20
o
to
25
o
C, the
ASTUTE140
®
Meter will allow approximately 10 user tests to be performed before requiring
battery replacement.
