Battery Maintenance
Under normal operating conditions, recharging the battery is the only
HI-3702 maintenance performed by the user.
Maintaining the HI-3702 requires that the nickel-cadmium (NiCd) battery be
properly charged and the battery condition monitored. The normal operational life
of the battery (approximately 1000 charge/discharge cycles) is such that by the
time the battery needs replacement; the HI-3702 will need recalibration; these
tasks are performed by ETS-Lindgren. For information on calibration services,
see Annual Calibration on page 10.
For the steps to charge the battery, see page 20.
In case of damage to the battery that causes premature failure, the HI-3702 must
be sent to ETS-Lindgren for battery replacement; replacement in the field is not
possible. See Service Procedures on page 11 for information on returning the
HI-3702 to ETS-Lindgren for service.
