(10) Auto Power Off (APO)
If the meter is idle for more than ≈ 10 minutes, the meter automatically turns the power off.
(11) Data Hold/Backlight
Pressing this button for less than 2 seconds, the meter enters the data hold mode, the HOLD symbol
appears on the LCD, and the momentary value while pressing the button is displayed on the LCD. Press it
again to exit this mode and the HOLD symbol disappears on the display. As the data hold function, this
button has no effect on the diode and continuity test functions. The secondary function of this button is to
enable and disable the backlight. If you press this button for more than 2 seconds, the backlight will turn on
and when you press it again for more than 2 seconds, the backlight will turn off.
(12) SELECT
There are positions on the rotary switch that have several functions. Pressing the SELECT button will select
the function you want in each position. It allows you to select AC or DC current, resistance, diode, audible
continuity, capacitance, ℃ or ℉ temperature measurement.
(13) RANGE
When powered on, the meter is in auto range mode. Pressing the RANGE button, you can select the
measurement range you want. The range goes up with each press of the RANGE button until its max, then
returns to the min range. Pressing the RANGE button for more than 2 seconds, the meter will return to auto
range. This button has no effect on frequency, duty cycle, capacitance, diode & continuity tests and
temperature measurement.
