◆
This device uses the True RMS method for AC wave detection, enabling it to
measure the root mean square values of both sine and non-sine waveforms.
(Accuracy is guaranteed for sine waves in the frequency range of 40 Hz to 400 Hz.)
◆In the 6.000 V AC range, a residual reading of approximately 3 to 9
counts may remain when the input is 0.
◆In the 600.0 V AC/DC range, whether set to auto or manual, an alarm
buzzer will sound if the measured value exceeds 600.0 V.
5-3 Resistance (Ω) Measurement
Never apply external voltage to the input terminals.
WARNING
【 】5 MEASUREMENT PROCEDURE
1.
Never apply an input signal exceeding the maximum rating input value
of each function.
2. Do not turn the FUNCTION switch during measurement.
3.
Always keep your ngers behind the nger guards on the probe during
measurement.
4.
After measurement, release the test leads from the object measured
and set the FUNCTION switch to the OFF position.
WARNING
5-1 Start-up Inspection
1.
When the POWER switch is turned ON, conrm that the low battery warning
is not blinking or lit on the display. If it is, replace the battery with a new one.
2.
Do not use the device if the main body or test leads are damaged or broken.
3. Make sure that the test leads and fuse are not disconnected or blown.

before conducting electric eld detection.
2. Exercise caution, as the object may not be entirely voltage-free; for
example, voltages below the detectable threshold may still be present.
WARNING
1) Measurement procedure
①Set the FUNCTION switch to ‘mA’ and use the SELECT button to
choose either DC or AC.
② Connect the red and black test pins in series with the load in the
circuit to be measured.
For DC mA measurements: Connect the black test pin to the negative
potential side of the circuit and the red test pin to the positive potential
side, ensuring they are in series with the load.
The alarm buzzer will sound if the measured value exceeds 600 mA
in either the auto range or manual range 600.0 mA AC/DC settings.

Even after the power is automatically turned off, a small amount of
power will still be consumed. Therefore, if the device will not be used for
an extended period, set the FUNCTION switch back to the OFF position.
To disable this function, press and hold the SELECT button while turning
the FUNCTION switch to the ON position. The display will show ‘dAPo’
for 2 seconds, and the clock icon will turn off.
with the test pins during measurement, errors may occur due to
the inuence of body resistance. The open voltage between the
input terminals is approximately 0.5 V.
1) Detection objective
To determine the presence or absence of voltage in AC voltage wiring.
2) Detection range
Sine wave AC voltage of 90 V or higher, at 50/60 Hz.
3) How to use this function
①
Bring the mark located at the upper-left corner of the device EF
close to or in contact with the target object for detection.
②
When voltage is detected, a “-” symbol will be displayed, and the buzzer will
sound on the ungrounded (hot) side.
④
The higher the detected voltage, the more “ ” symbols appear on the display —
(up to 4), and the buzzer’s intermittent beeping will increase.
Notes:
･ In cases where the wiring is long, detection may also occur on the grounded side.
･
Depending on ambient conditions, the device may activate even when the
EF mark is not brought close to the target object.
