REPLACEMENT OF BATTERIES

△

！

WARNING

POSSIBLE ELECTRICAL SHOCK OR ACCIDENT

●Do not replace the batte

ries under the conditions of measuring current or

voltage

●Do not operate the instrument with battery cover off.

△

！

CAUTION

When not using the

instrument for a long period, remove the batteries and keep

separately. The batteries may leak and may cause damage to the instrument.

●「B」sign will appear on the display when batteries are exhausted and get less

than operation voltage. Replace to new batteries immediately.

●Do not use the batteries mixed new one and once used and or different kind ones.

〔How to replace the batteries〕

●Remove the screw fixing battery cover

at the bottom of rear case by + driver

and slide & remove the battery cover

to the direction of arrow mark.

●Pick up the exhausted batteries.

●Confirm the polarities and put the new

batteries.

●Replace the battery cover to the original

position and fix screw by driver.

MEASURING METHOD

For the safety operation keep and pay attention to the cautions and warnings stated in

this manual.

△

！

WARNING

POSSIBLE ELECTRICAL SHOCK

●This instrument is for the use of low voltage circuit.

Do not make measurements of power lines carrying more than AC 60 0V.

Before use, check and confirm the voltage of circuit to be measured.

POSSIBLE ELECTRICAL SHOCK OR ACCIDENT

●

Do not handle the instrument in the rain, at humid place, with a drop of water

and or with wet hands.

●

Do not use the instrument if the CT or CT case are damaged and if something is

wrong with the CT cables.

●Do not use the instrument, leaving the battery cover off.

●

If excessive current is applied to the CT, the instrument will be heated and

damaged. Use the CT according to the rating current.

※Note : The display may not become “0” at power on promptly but it is not defect

or abnormal. (it takes a time.)

It will take a time to get the stable display at 1000mA & 10A range due to wide

range measurement.

(1) Line Current Measurement

1) Set the range switch from OFF to 200A (display on).

2) Open clamp jaw and clamp CT to the conductor to

be measured and close CT completely.

3) Select the most suitable range by range switch and

read the displayed value.

(In the place where hardly can read the display,

use data hold function).

Note : The power will become automatically off

approx. 10 minutes after the final operation

of range switch due to auto power off function.

(2) Leakage Current Measurement

1) Measurement at grounding line

Do the same method as for line current measurement, and use the measuring

ranges 1000mA and 10A.

2) Measurement for other circuit except for grounding line

The operations are the same as for line current but clamp CT to 2 wires en bloc in

case of single phase and 3 wires en bloc in case of 3 phase.

Note: In case of not using 2CT Method, make measurement by applying the cover to

2CT INPUT terminals.

(3) 2 CT Method Leakage Current Measurement

Can measure leakage

current where CT cannot

be applied to the

conductors en block in

the distribution circuit

board like as a drawing

on the right, by using

spare CT (CTP-05-2). In

this case, make the

instrument and spare CT

to the same direction.

*Can measure line current by using spare CT only.(Max. 10A)

1) Insert spare CT (CTP-05-2) to the terminal of 2CT INPUT.

2) Set the range switch ③from OFF to 10A (display on).

3) Check the line current of circuit to be measured and confirm if it is less than 10A.

(The max applicable current of spare CT CT-05-2 is 10A).

4) Set CT Selection Switch ④to φ5.

5) Clamp CTs respectively like as drawing.

6) Observing display value, set the most suitable range and read the value. (In case of

over range, “DL” mark appears on the display).

Note:

●In case that CT direction is not same, the display value will become twice of line

current.

●In case of using 2CT Method, put the conductor to be measured in the center of CT.

●Be careful not to lose terminal covers for 2CT INPUT terminals.

●Can measure line current by applying spare CT only.

●In case of 2CT method measurement for low range, it will take a time to get stable

value due to wide range measurement.
