Relative Measurement Mode Switch

Press "REL" key to enter the relative measurement mode. When making
relative measurement, the measurement value at the moment of pressing
REL key in the internal memory of the meter is called initial value. The display
value after that is the current measurement value - initial value.

Duty Ratio And Frequency Measurement Choice

• Press "Hz%" key at Hz grade. The meter will enter the duty ratio
measurement state. Press "Hz%" key again. The meter will enter
frequency measurement state.

Function Switch

• When measuring voltage and current, press"FUNC" key to switch AC
voltage and AC current.
• When measuring resistance, diode or continuity. press "FUNC" to switch
different measuring signals.

Backlight

• Press key to open the backlight, the backlight will automatically trun off
after 20 seconds.

Automatic Power-off

• If there is no operation for 30 minutes after turning the machine on, the
meter will automatically power off to save the battrery.
• After automatic power-off, press any key to turn the meter on again.
• Holding the "FUNC" key when powering on will cancel automatic power-
off function.

NCV (non-contact Voltage Detection)

• Turn the meter to NCV grade
• Place the meter top close to the conductor.
When test voltage is greater than 110 Vac (RMS), the meter induction
voltage indicator willturn on and buzzer will give dripping alarm sound.
Note:
1. Even there is no indication, voltage may still exist.
Don't use non-contact voltage detector to judge whether there is
voltage in the wire. Detection operation could be affected by socket
design, insulation thickness, type and other factors.
