4.1 Reading hold
During measurement, if it is required to hold
reading,
touch
button,
value on display
will be locked, touch
button again, to cancel reading hold.
4.2 Backlight/Light
1)
During measurement, if environment light is too dark,
causing it difficult to read, you could press
key
for more than 2 seconds, to open backlight or light,
which will turn off in about 15 seconds
automatically.

4.3 Automatic shutdown
1) If there's no operation within 15 minutes after start,
instrument will enter standby state, and shut down to
save energy.
2) After automatic shutdown,
wake the instrument enter work state.

4.5 NCV (Non -contact voltage detection)
Switch the rotation switch to any gear, hold down the
"NCV" key to display EF, and bring the NCV sensor close to
the conductor under test, instrument could detect whether
the lead being measured is >90V AC voltage. When
instrument detects AC voltage, instrument buzzer will
alarm and NCV alarm light will flash.
Note:
1)
Even if there’s no alarm indication, voltage may still
exist. Do not depend on non-contact voltage detector
to judge whether there's voltage in the lead. Detection
operation may be impacted
by factors like different
socket designs and insulation thickness types etc.

5. Maintenance
5.1 Change battery
Warning
Before opening battery cover of the
instrument, remove the pens from the circuit being
measured, to avoid electric shock.
1) If symbol "
" appears, it indicates to change the
battery.
2) Unfasten bolts on battery cover of instrument and
remove the cover.
3) Change the old battery.
4) Place the battery cover.
Do not reverse battery polarity.
5.2 Change pens
Warning
When changing the pen, it is required to
replace with an identical pen or a pen of the same
level.
The pen must be in good condition, and level
of the pens is: 1000V 10A.
If insulation layer of the pen is damaged, or metal wire
of the lead exposes, it is required to change the pen.
