for capacitor with small capacitance, please perform measurement
Δ
by using the relative function ( ) , the clamp meter will subtract
the intrinsic capacitance.
Note:
"OL" is displayed if the measured capacitor is shorted or its
capacitance is over the maximum range.
For large capacitance measurement, it is normal to take several
seconds to stabilize the reading.
To avoid product damage and personal injury, please discharge
the capacitor (especially capacitor with high voltage) completely
before measurement.
7. Live/Neutral Wire Measurement (Figure 3)
Figure 3
1) Short press LIVE at voltage position to enter function
measurement.
2) Connect the red test lead with "LIVE" terminal, suspend
the black test lead, then the red test lead makes contact with
outlet or bare wire, to identify live wire or neutral wire.

3) "- - - -" is displayed when neutral wire is detected.
4) If AC live wire with voltage of ≥70V is detected, "LIVE" is
displayed along with audible and visual indication.
Note:
To avoid affecting the accuracy of identifying live/neutral wire,
please remove the black test lead from COM terminal when
performing LIVE measurement.
8. Other Functions
The product enters normal measurement state when all symbols
are displayed after the product is powered on.
If the rotary switch is not turned in 15 minutes during measurement,
the product will enter "Auto-off" state to save power. If any
button is short pressed or the rotary switch is turned in auto
-off state, the product will be awakened and the buzzer beeps
once. To disable the auto-off function, please set the rotary
switch at "OFF" and hold down SELECT at the same time to
power on the product.
About one minute before the product powers off automatically,
the buzzer continuously makes sound for 5 times. The buzzer
makes a long sound for once before
The buzzer beeps about 0.25 second for once when any
functional button is pressed.
The buzzer makes warning sound during measurement: If the
voltage is ≥600V under DC and AC voltage functions, the
buzzer intermittently beeps to warn the range is at extreme
limit.
Low voltage detection: The internal voltage of battery is detected
when the batteries supply power. The low battery symbol
" " is displayed if the battery voltage is lower than about
2.5V (the product can still work normally). If the battery voltage
is lower than 2.4V, the symbol "Lbt" appears on the VLCD
and flashes for 5 seconds, with buzzer
times, then the product powers off automatically.
