Users Manual
Controlling Meter Power
The Meter is powered by six AA batteries and controlled through
a front panel power switch and internal circuits designed to help
conserve battery power. The following sections describe several
techniques for controlling Meter power.
Powering the Meter On and Off Manually
With the Meter off, press O to turn on the Meter. Pressing O
while the Meter is on causes it to turn off.
Battery Level Indicator
The battery level indicator in the upper left-hand corner of the
display indicates the relative condition of the batteries. Table 6
describes the various battery levels the indicator represents.

Collected data is retained when the Meter is turned off
while in record, MIN MAX record, or Peak record
modes. When the Meter is next turned on, the dispay
shows the collected data in stopped mode. Pressing
the softkey labeled Save will save the data.
Note
The Meter will display a “Batteries low” message whenever the
battery level will not support a selected function.
Automatic Power-Off
The Meter automatically turns off if the rotary switch is not moved
or a button is not pressed for 15 minutes (default). Pressing O
will turn the Meter back on after it is powered off automatically.
To change the timeout period or completely disable automatic
power-off, refer to “Setting Backlight and Auto Off Timeouts” later
in this manual.
Battery Saver Mode
If Auto off is enabled (set to a time period), and MIN MAX record,
Peak record, Recording, or AutoHold is enabled, the Meter will
enter a battery-saver mode if a push-button is not pressed or the
rotary switch is not moved for a set period of time. For the
