Martel Electronics IVC-222HPII - Manual (Page 9)

5. Maintenance
Generally, with normal usage, the calibrator
should hold its rated specifications for at least
12 months. Beyond this, it should be returned
for re-calibration annually. If after the stated
warranty period, the device falls out of
calibration, or needs repair, it can be returned
to Martel Electronics for re-calibration. Please
use our website www.martelcorp.com under
Customer Service for return information.
6. Rechargeable Battery
Option
When continual service is required, a
rechargeable “NI-Cad” 9V battery and wall
mount AC adapter/charger may be purchased.
The AC adapter may be left on continually to
keep the charge up on the battery while the
instrument is in use or can be used to recharge
a low battery over a 12-14 hour period. The AC
adapter/charger can also be used solely as an
AC power supply without battery installed.
When using the “Ni-Cad” battery, it is advisable
to occasionally allow the instrument to operate
until the “BAT” indicator appears then recharge.
This procedure will cycle the battery and
prevent any “memory” effects that are
associated with this type of battery.
