2.1.4 Preparing the 831C for Long Term Storage
The Hardware Power Switch on the bottom of the 831C disconnects the batteries from the
831C hardware. (For reference, see
.) The real-time clock maintains its value
while the switch is off. The power switch prevents battery drain when the meter is not in
use for an extended period of time. If you plan to store the meter for more than 2 weeks,
remove the batteries.
If the switch is in the “ 0 ” position, the batteries are disconnected. After installing
batteries be sure to move the switch to the “ | ” position.
CAUTION
DO NOT use the hardware power switch to turn the 831C OFF. Permanent
damage and data loss may occur. Press the
Power
button once, then select
