[2] APPLICATIONS AND FEATURES
2-1 Applications
This instrument is a voltage tester of the RMS value response type
equipped with the electric field detection facility. It is designed for
measurements in the ranges specified by IEC 61010-1 CAT. IV 600 V
and CAT. III 1000 V.
Recent multiinstruments have been increasing the facilities and
becoming capable of measuring a larger variety of items in simpler
ways. Nevertheless, this trend also means that the risk of operation
mistake is increasing because of the presence of facilities that are not
required by all of the users.
This instrument has been designed to meet the actual needs of the fields
of electrical equipment maintenance by prioritizing the usage without
operation mistakes, reducing the size for higher portability and limiting
the facilities to voltage measurement and electric field detection while
complying with safety standards. It is suitable for voltage measurement
and electric field detection of low-voltage lines and equipment.

removing it from the
main body, positioning
it in the desired angle
and inserting it straight
into the main body.
Be sure to insert the
measuring probe all
the way until it is fixed.
4-2 Power/Select button
The function of the Power/Select button varies depending on the period
it is pressed. In this manual, we use the term “push for the action of
pressing the button temporarily and the term hold” for the action of
pressing and holding the button for more than one second.
Hold this button to turn the instrument ON/OFF. Note that the instrument
cannot be turned OFF while it is accepting an input.
Push the button while the instrument is ON to switch the measurement
modes.
The instrument is in the self-test mode ( displayed) when it is
turned ON. Thereafter, each press of this button switches the modes
in the following cycle. (For the description of each mode, see
[5]
MEASUREMENT PROCEDURE.)
Auto-identifying voltage measurement mode ( displayed)
EF mode ( displayed) Auto-identifying voltage measurement
mode (repeat)
4-3 Auto power OFF
When the instrument is left without input for about one minute since the
last operation, Auto power OFF turns automatically the display and the
power of the instrument OFF. To recover from the auto power OFF, hold
the Power/Select button for more than one second.
4-4 Low battery alarm
When the built-in batteries have been discharged and the battery voltage
has dropped to below about 2.5 V, mark appears on the display.
When this mark appears, replace both of the two batteries with new ones.
If the battery voltage drops below about 2.2 V, appears on the
LCD and the instrument becomes unable to continue measurement.
4-5 Backlight and LED light
The LCD green backlight and the LED light light when the instrument
is turned ON. The backlight color changes to orange when the input
is AC or DC and 20 V or more, or when the AC live wire is detected in
the EF mode.
* The light cannot be turned OFF except by turning the instrument OFF.
4-6 Self-test
This self-test checks disconnection of the test lead wires, lack of
display segments and failure of the buzzer and buzzer LED light.
For details, see 5-2 Self-test mode.
4-7 AC/DC auto-identifying voltage measurement
When an input of 5 V or more is applied in the self-test or auto-identifying
voltage measurement mode, the instrument automatically identifies
whether the input is an AC or DC voltage and displays the measured value.
4-8 Auto hold
When the probe is separated from the measurement target during
auto-identifying voltage measurement or when the input drops below
about 5 V, the instrument automatically holds the last measurement
value displayed on the LCD. During auto hold, appears on the
LCD and the displayed value flashes.
* A numeric value other than the measured value may appear momentarily
before the held value is displayed, but this is not malfunction.
4-9 EF (Electric Field) detection: EF button
This EF detection identifies the presence of voltage in a simple
manner by detecting an electric field generated by an AC voltage.
For details, see 5-4 EF (Electric Field) detection.
4-10 AC detection method
This instrument employs the RMS (Root-Mean-Square) method and
indicates the magnitude of AC current as the same amount of work as
DC. RMS values of sinusoidal waves and such non-sinusoidal waves
as square and chopping waves can be measured by the true RMS
circuit. (The input signal measurement value is used as the scale of the
actual input signal power so it is therefore measured as a more
effective value than the value obtained by average detection ).
4-11 CF (Crest Factor)
The CF (Crest Factor) indicates the peak value of a signal divided by
its RMS value. With most common waveforms such as sinusoidal and
chopping waves, the CF is relatively low.
With waveforms similar to pulse trains with low duty cycle, the CF is high.
For the voltages and CFs of typical waveforms, see the table below.
The CR of measurements should be 2 or less.

[5] MEASURING PROCEDURE
1. Do not apply an input signal exceeding the maximum rated input value.
2. During measurement, do not hold the instrument by a position on the
test pin side of the barrier on the test probe.
3. Use test leads matching the measurement category of the measured
point.

The following instructions are intended to prevent injury such as burn
and electric shock. Be sure to follow them when using the instrument:
1. This instrument is a voltage tester equipped with the electric
field detection facility. Do not use it with an electric circuit
exceeding 1000 V.
2.
Voltages over DC 70 V or AC 33 V rms (46.7 V peak) are
hazardous to human body. Take care so as not to touch them.
3.
Never input signals exceeding the maximum rated input value
(see 1-3).
4. Never use the instrument for measuring a line connected to
equipment that may generate induced or surge voltage (such
as a motor) because an input exceeding the maximum
allowable overload input may be applied.
5. Never use the instrument if the instrument or test leads are
damaged or broken.
6. Never use the instrument with the case or battery lid removed.
7. During measurement, do not hold the instrument by a position
on the test pin side of the barrier on the test probe.

5-4 EF (Electric Field) detection
1. Before proceeding to the EF detection, check the proper
operation of this instrument using a known power source.
2. During EF detection, do not hold the instrument by a position
on the test pin side of the barrier on the probe.
3. Do not touch the power line because it is not always voltage-
free but there may be a voltage below the detectable voltage.
WARNING
EF detection identifies the presence of AC voltage in a simplified
manner, by detecting the electric field generated by it.
The standard detection level is from about 60 to 1000 V AC. When
an electric field is detected, the LCD backlight changes color from
green to orange, and the number of bars, the intervals of buzzer
beeps and the flashing interval of the buzzer LED vary in five steps.
Push the Power/Select button so that the LCD shows in the
main numerical value display area.
Check method
Noncontact type measurement: Position the antenna as shown in
the illustration (on the right side of the light when the instrument is
viewed from the front).
Contact type measurement: Bring the test pin (either the black or
red one) in contact with the target. More accurate EF detection is
possible so that the buzzer does not beep and the display
remains in the grounding phase.
* In certain cases in which the wiring is long, for example, may
sometimes become “
-
even on the grounding side.
* Due to the high sensitivity, the EF sensing may be activated near
an inverter generating high frequencies, even when it is as apart as
more than some tens of centimeters from the instrument.
