4. Operation Guide
4.1. Readings Hold
During the measuring process, if the readings are required to
hold, slightly touch key, the display value will be locked,
slight press key again to cancel readings hold.
4.2. BackLight
1
）
In the process of measurement, if the ambient light is too
dim, causing reading difficulties, press key for more
than 2s, open BackLight and it will automatically off after
about 1 minute.
2
）
During the process if press key for more than 2s,
then the BackLight will be turned off.
4.3. Auto Power Off
1
）
If after 10 minutes when the meter is on without any
operation, it will go into hibernation and automatically shut
down to save power. Before the meter off, there will be one
sound of the buzzer to remind every 1 minute.

When turn the meter on, hold the "NCV" key at the same
time, then the auto power off function is canceled.
4.4. Measurement Preparations

）
Turn the transfer switch, turn on the power. If the battery
voltage is low (of about ≤2.4V), the LCD will show “ ”
symbol, then the battery shall be replaced.

）
When the meter has not entered into measurement, it will
automatically enter into the status of automatic scan, the
meter displays as the following diagram shows.
4.5. Non-contact Voltage Detection (NCV)
1) Press NCV key for 2s, enable NCV function, the meter
displays.
