Important Points About Taking Measurements

Grounding

If the user's body retains an electrical charge, or highly accurate measurements are
required, ground the earth terminal of this device. Also, if the charged object is expected to
have a large charge, be sure to ground the device to avoid breakdown due to discharge.

Adjusting the Measurement Distance

The strength of the electrical field of a charged object changes with the distance between
the charged object and the sensor portion of the measuring instrument. This device has
been calibrated with a distance of 30mm between a test charged object (200mm2 metal
plate) and the meter. Consequently, when measuring it is necessary to conform to a
measuring distance of 30mm. Move the meter so that the illuminated point on the charged
object emitted by the pointer (red LED) is sharpest. If such a distance cannot be attained,
correct the potential reading according to Figure 1.

If the distance is more than the recommended measuring distance of 30mm, and the
displayed potential exceeds 19.99kV, do not move the meter any closer to the charge
object.

If the meter is too close to the charged body, there is the danger of an
electrical discharge. This may cause a breakdown of the device.

Influence of the size of the charged object

The measured potential changes according to the field strength concentrated in the
electrode of the sensor portion of the meter and the size of the charged object. In particular,
if the charged object is smaller than the test charged object used during calibration
(200mm2), there is a large discrepancy in the measured value and an error can occur in the
resulting value. if this is the case, you can roughly correct the value according to Fig. 2.

Influence of other objects

If there are other objects near or behind the charged object, the displayed measurement is
smaller than the actual potential. If this is the case, correct the measurement in light of the
shape of the electrical field, or put as much distance as possible between the charged
object being measured and other objects.

Influence of charged particles etc.

Powerfully charged objects impose a charge on particles and create an ionic space. If
charged particles etc. adhere directly to the electrode of the meter, measurement errors will
occur. This phenomenon occurs when a large amount of fluff adheres to the charged object
or large amounts of dust are in the vicinity.

Preparation

1. Insert the battery.

Remove the battery case cover and insert
a 9 volt dry cell battery. Replace the cover
carefully, taking care to keep the battery
leads clear of the cover.

2. Connect the earth lead to the
earth terminal, and reliably
ground the earth lead.

Connect the earth lead securely to the
terminal, and connect the clip on the end
of the earth lead to a grounded object. To
obtain accurate measurements, the earth
terminal must be grounded.

Measurement Procedure

Measuring Static Electricity

1. Turn the meter on.

Press the POWER button for more than
one second, until you hear a beep.

2. Set the mode you want to use.

Each time you press the mode button, the
meter scrolls through the modes in the
order shown in the table on the right. To
measure potentials, use the normal mode.

3. Zero point adjust the meter.

Point the sensor at a grounded object and
press the 0ADJ button.

NOTE

 Zero point adjustment is reset when

you turn the meter off.

4. If you want to measure a maximum potential, use the MAX
mode.

Refer to step 2 for how to set modes.

5. Point the sensor at the charged
object, and gradually bring the
meter closer to the object.

The distance between the sensor and the
charged object should be 30mm. At about
30mm, the red LED beam (pointer) cast on
the charged object should look like the
image in Figure 3.

(Fig. 3) Red LED mark

NOTE

 If the recommended measuring distance of 30mm cannot be attained, do not

bring the meter any closer if the potential displayed exceeds 19.99kV. Doing
so may cause damage to the meter.

 If the display panel blinks "1", the charged voltage has exceeded the

measurable range (over-range). If this occurs, stop measuring immediately, as
this may cause damage to the meter.

6. The value on the display panel is the measurement result (unit:
kV).

7. In normal mode, you can temporarily hold the measured value
by pressing the hold button.

If you press the hold button again, the stored value is removed.

You cannot use the hold function in MAX mode.

8. To turn the meter off, press the POWER button for more than 1

second.

Measuring Ion Balance

By attaching the optional ion balance plate (sold separately) to the meter, you can measure
ion balance (offset voltage).

1. Turn the meter on.

Press the POWER button for more than
one second, until you hear a beep.

2. Set the mode you want to use.

Each time you press the mode button, the
meter scrolls through the modes in the
order shown in the table on the right. To
measure offset voltages, use the I.B mode.

3. Zero point adjust the meter.

Point the sensor at a grounded object and
press the 0ADJ button.

NOTE

 Zero point adjustment is reset when you turn the meter off.

4. Attach the ion balance plate to
the meter.

Firmly screw the ion balance plate onto the
meter with the screw provided, making
sure that it is centered and there is no gap.

5. If you want to measure the maximum value of an offset voltage,
use the MAX I.B mode.

Refer to step 2 for how to set modes.

The potential on the ion balance is
measured.

NOTE

 If the display panel blinks "1", the charged voltage has exceeded the

measurable range (over-range). If this occurs, stop measuring immediately, as
this may cause damage to the meter.

7. The value on the display panel is the measurement result (unit:

8. In I.B mode, you can temporarily hold the measured value by
pressing the hold button.

If you press the hold button again, the stored value is removed.

You cannot use the hold function in MAX I.B mode.

9. To turn the meter off, press the power button for more than 1
second.

Adjustment and Maintenance

Rotating the Sensor Head

You can rotate the sensor head of the meter. This
enables you to easily take measurements in
narrow locations etc. that were previously difficult
to access.

The sensor head rotates in 45° increments. When
rotating the head, stop at angles where the sensor
head clicks into place.

Battery Indicator

The remaining battery charge is displayed on the
upper right of the display panel.

When the battery charge icon shows one unit left,
replace the battery.

Error Display

The signal detection method of the meter is an
oscillating chopper method.

If for some reason the sensor stop oscillating, an
error message like that shown in the illustration on
the right is displayed, and the meter emits a
beeping sound every second.

If this occurs, restart the meter. If the error
message continues to be displayed after restarting
the meter a number of times, the sensor may be
faulty. Contact the sales office where you
purchased the product.

Troubleshooting

If the device does not operate correctly, it may be the result of one of the following.

The display panel is not active when the power is turned on.
Cause 1

The battery has not been installed, or the positive and negative

terminals have been connected the wrong way around.
Remedy 1 Correctly install the battery.
Cause 2 The battery has been completely drained.

Remedy 2 Replace the battery with a new one.

The display panel displays correctly, but does not zero.
Cause 1 Zero point adjustment is incorrect.

Remedy 1 Perform zero point adjustment again.

Cause 2 Structural components close to the sensor are charged.

Remedy 2 Wait until the charge in the components has attenuated.

The display does not change even when approaching a charge object.
Cause 1 The meter is holding a maximum value in MAX mode or MAX I.B

mode.
Remedy 1 Press the mode button to switch modes.

Cause 2 The meter is holding a measured value in normal mode or I.B mode.

Remedy 2 Press the hold button and start measuring again.

Cause 3 The sensor is faulty.
Remedy 3 If an error message is displayed or you cannot hear an oscillating sound

from the sensor, the sensor must be replaced. Contact the sales office

where you purchased the product.
