Function Controls
On/Off
The ON/OFF push-button, when pushed, actuates power on or power off with an audible
control tone. Upon initial power-up, the instrument will be in the Ohms function (Ω) and
will go to OL until clamped on. When the ON push-button is pushed and held down, after
three seconds the instrument will beep and provide a self test featuring a full function
display (Fig. 3) followed by status indications for status of remaining battery life
(battery symbol blinks, 0-100%) (Fig. 4).
Release the ON/OFF push-button to initialize the instrument.
Auto-Off
The instrument will shut off automatically after
five minutes of non-use. The instrument will
issue a short beep 15 seconds prior to shutting
down and the LCD flashes once per second.
The Auto-Off may be disabled by turning on the
meter while holding down the HOLD button.
The indicator will appear on the display to
indicate the Auto-Off feature has been disabled.
