2. Remove the old battery.
3. Place the new battery in the battery compartment. Be sure to observe proper polarity.
4. Re-install the battery cover before resuming use of the instrument.
NOTES:
• Less than 10% of battery life remains when the BAT annunciator turns on.
• When the battery is excessively discharged, the display is blanked.
• If the instrument is going to be stored for a long period of time or in a high
temperature environment, remove the battery to prevent leakage damage.
• After a new battery is installed, allow approximately 5 seconds for
display turn-on the first time the unit is turned on. During this period,
microcomputer initialization is performed.
MEMORY BACKUP
During battery replacement, the contents of user-programmed memory (data, operating modes,
etc.) can be saved. Prior to removing the old battery, turn off the instrument, and connect an
HH22-AC battery charger. Then exchange batteries, and disconnect the battery charger. Do not
leave the battery charger connected to instruments with non-rechargeable batteries.
OPERATION WITH RECHARGEABLE
BATTERY
HH22-AC provides a 9-volt Ni-Cd battery and recharger suitable for use with the unit. This
battery provides 3-4 hours of continuous operation. This duration can be extended to several
days by operating simultaneously from both the battery and recharger.
Turn off the instrument to recharge the battery. Allow 7 hours to fully recharge the battery.
Then unplug the recharger to avoid overcharging.
