Synchronizing The Battery Charge Indicator
The probe has internal circuitry to track the charge condition of the
batteries. NiMH batteries have a sharp discharge-curve knee, which means
there is little indication that the batteries are nearly discharged prior to a low
battery condition. The internal circuitry tracks the charging and discharging
currents of the batteries and displays the calculated battery condition.
It is possible that the battery charge indication may lose synchronization
with the actual battery condition. A loss of synchronization may be indicated
by a low battery charge alert after the batteries were recently fully charged.
Loss of synchronization may also be indicated by short battery life and
premature low battery alert.
To synchronize the battery charge indicator:
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.
3. Press the DISCHARGE button on the battery charger. The batteries
will fully discharge, and then fully recharge. The total time required to
discharge and recharge is approximately seven hours.
4. For best results, repeat the process once. However, it may be necessary
to repeat the process three times for proper synchronization. The
synchronization process may take up to 12 hours.
When completely charged, the battery indicator for the probe should
indicate a charge level of more than 90%.
Discharging a Battery
To discharge the batteries:
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.
3. Press the DISCHARGE button on the battery charger. The batteries
will fully discharge, and then fully recharge. The total time required to
discharge and recharge is approximately seven hours.
