[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.

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.

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

① 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.

② Push the Power/Select button so that the LCD shows in the

main numerical value display area.

③ 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.
