back of the Meter.

Battery Considerations

The Meter uses one 6pcs X 1.5V Battery (R14) or
AC200V~240V 50Hz. The following paragraphs describe
several techniques used to conserve battery power.

Automatic Power Off

Under battery operated situation, the display blanks
and the Meter goes into a "sleep" mode if you have not
changed the rotary switch position or pressed a button
for a set period. While in Sleep mode, pressing the
EXIT button or turning the rotary switch could turn the
Meter on. The Meter then returns to the display for the
function selected with the rotary switch; all previously
activated button features are discarded.
The automatic power off is preset to 10 minutes. From
the Setup menu (see Chapter 5), you could specify a
time (10 minutes, 20 minutes, 30 minutes or OFF). If
you set to OFF, the Meter retains on until you turn the
rotary switch to OFF or the battery becomes too weak.
Under AC operated situation, the automatic power off
feature is invalid.

Automatic Backlight Off

LIGHT button for around 1 second to turn the backlight
on. Press EXIT to exit the feature
In Setup menu (see Chapter 5), you could specify a
time to automatically turn off the backlight (10 seconds,
20 seconds, 30 seconds or OFF). If the period is set
