ets-lindgren.com Series H-491198-01 Battery Charger 75
Fully charged batteries (nominal output voltage of 4.8 VDC) provide up to
30 hours of operation. When the batteries have discharged to 4.4 VDC, the probe
will operate, but the batteries need to be charged. When the voltage drops below
4.0 VDC, measurement accuracy may be compromised by continued operation.
When the battery voltage indication is less than 4 volts, a low battery indication is
attached to the output data string warning of the problem. ETS-Lindgren software
applications provide a warning indication on the display screen of the readout
device. It is recommended that custom software packages using data from the
probe monitor the data output for this condition.
If the batteries exhibit low terminal voltages during charging, or if they appear
unable to acquire or maintain a charge, the batteries may be shorted or
damaged. To replace the batteries, see HI-6053 Battery Replacement on
page 26.
Charging the Batteries
For maximum battery life, fully charge the batteries before placing the probe into
service. Failing to fully charge the batteries may result in reduced battery life and
cause premature battery failure.
To charge a battery:
1. Make sure the probe is off or the batteries will not charge.
2. Connect the battery charger to the electrical mains, and then plug the
charger output into the battery charger connector on the probe.
Caution: Never attempt to recharge a non-rechargeable
battery.
