The instruments stops to operate when the low battery signal is
detected. This is indicated by the code "Eb" in HI9063 and "BAT" in
all other items.
Battery replacement must only take place in a non hazardous area
using the battery types specified in this instruction manual (see page
17).
To install the batteries, turn the unit over
and unscrew the 2 screws on the battery
cover.
Remove the battery cover exposing the
battery compartment as shown in the

batteries prior to installation.
Place the batteries in the compartment
while paying attention to their polarity
(see diagram). After the batteries are
installed, replace the battery cover to
the back of the instrument.
