Tips

This section is information and tips on how to best use
the Test Tool.

Battery Life

For battery operation, the Test Tool conserves power by
shutting itself down. If you have not pressed a key for at
least 30 minutes, the Test Tool turns itself off
automatically.
Automatic power shutdown will not occur if Record is on,
but the backlight will dim. Recording continues if the
battery is low. Retention of memories is not jeopardized.
To save battery life without automatic power shutdown
you can use the display AUTO-off option. The display
turns off after the selected time (30 seconds or 5
minutes).
If the power adapter is connected, automatic
power shutdown and the display AUTO-off
function is disabled.
