B ATTERY L IFE
A fully-charged battery (nominal output voltage of 3.6 VDC) provides up to 40
hours of operation. When the battery has discharged to 3.3 VDC, the probe is still
operational, but the battery needs charging. When the voltage drops below
3.18 VDC, measurement accuracy will be compromised by further operation.
Follow these recommendations to ensure maximum battery life and optimum
testing performance:
• Operate the probe only within the optimum operating temperature
range of +20 ° C to +30 ° C (+68 ° F to +86 ° F). Although NiCd batteries
are rated for operation in temperatures from -20 ° C to +65 ° C
(-4 ° F to +140 ° F), operating the probe at temperature extremes
reduces the operating time of the batteries.
• Make sure the battery is fully charged before resuming operation. The
battery does not require periodic deep discharges to reverse the effect
caused by repeated shallow discharges, but undercharging can reduce
battery capacity.
If the battery exhibits low terminal voltages during charging, or if it appears
unable to acquire or maintain a charge, individual cells in the battery may be
shorted or damaged. If your battery needs replacement for any reason, contact
ETS-Lindgren Customer Service.
C HARGING A B ATTERY
1. Make sure the power switch on the probe is set to the OFF position or
the battery will not charge.
2. Connect the battery charger to the proper power source, and then
connect the charger to the charger jack on the probe.
Charging takes approximately one hour, depending on the degree of
battery discharge. When charging is complete, the battery charger
automatically enters into a trickle charge, and continues until the probe
is disconnected.
Never attempt to recharge a non-rechargeable
battery.
