1.4 POWER SUPPLY

HI9828

HI9828 is supplied with 4 rechargeable C size, Ni-MH batteries.
The battery symbol on the LCD shows the remaining battery charge. When the
symbol starts blinking, batteries should be charged or replaced with new ones.
When the batteries are completely rundown the meter automatically shuts off to
avoid erroneous readings.

1.4.1 Battery Installation
Battery replacement must only take place in a
nonhazardous area.
Remove the 4 screws on the rear of the instru-
ment and insert the batteries while paying at-
tention to the correct polarity.
If using rechargeable batteries, move the switch
down toward the probe connector. Move the
switch upward for not rechargeable alkaline bat-
teries.

Not rechargeable batteries can explode or leak if attempting
to charge them with the switch set to down position.
