CAUTION
Never short the output of a NiCad battery
(even a discharged battery). The resultant
currents will be large. This will cause the
lead wires to become extremely hot which
can cause severe burns and/or fire.
6.0 Maintenance
Battery Replacement
The battery pack used in the HI-3627 Magnetic Field meter is a
commonly available NiCad battery pack (Holaday part #
491044, 9.6 Volt, 600 mA-H, or equivalent). In the event of
battery failure, a new battery can be obtained from Holaday
Industries or from a local source.
The battery pack is replaced by removing the back cover of the
meter, unplugging the battery, and removing the battery
retainer. Replace the battery pack by reversing these steps. The
back cover is fastened by six screws that can be found around
the lip if the front panel. The battery is retained by two more
screws and a metal strap that holds the battery in place (a #1
Phillips screw driver will work well for these operations).
