1.4 POWER SUPPLY

HI9828

HI9828 runs with 4 rechargeable C size, Ni-MH batteries.
On the display the battery symbol visualizes the remaining battery charge. When
this symbol starts blinking, it is necessary to recharge or replace them with new
ones. When the batteries are completely rundown the meter automatically shuts
off to avoid wrong readings.

1.4.1 Batteries installation
Battery replacement must only take place in a
nonhazardous area.
Remove the 4 screws on the rear cover of the
instrument and insert the batteries while paying
attention to the correct polarity.
Move the switch down toward the probe con-
nector if using rechargeable batteries. Move the
switch up for alkaline batteries.

Alkaline batteries can explode or leak when attempting to
recharge them with the switch set to down position.
