"PUSH TO OPEN" mechanism.

2. CAUTION

* Before operating this instrument, familiarize yourself with instruction outlined
in this manual. .

* Always check to make sure that the function switch is set to the proper position.

* To avoid electrical shock, operate this instrument very carefully, especially for
the measurement of the circuit with more than AC 1000V.

* As the high voltage circuit is very dangerous, those who do not have such

specialized knowledge must not use this instrument.

* Never make measurements for uninsulated conductors or bus bars.

* Do not use this instrument, if you find any damage on the instrument of CT and or
body case.

* Through this instrument is sealed to withstand water, avoid the operation of this
instrument under heavy rain and humidity for the safety.

* Do not disassemble this instrument.

* When [B] sign appears on the display during the use of this instrument, replace the
batteries to new ones, as the operation voltage gets below than normal use for the
measurement.

* This model is high precision measuring instrument.
It may cause defect, if the CT part receives damage.

3. CARRY AND STORAGE

* Take care not to drop down the instrument and or not to load heavy weight and
or strong shock to the instrument.
* Do not apply chemicals to this instrument.
* Do not leave this instrument on the road and or the place under the direct sunshine
during summer and also do not leave it in the high temperature place, such as
inside of the car, etc.
* Keep the instrument clean and chose the storage place where is dry and not getting

direct sunshine.

6. METHOD OF MEASUREMENT

6-1. Preparation and Caution before Measurement

* Before making measurements, install the batteries.
* Check if there are no damage or unusualness on the instrument.
* Check the battery by switching the power on.
* Do not change the batteries, keeping clamp of the instrument on the wire.
* Remove the batteries, if the instrument will not be used for a long period
of time.
* Do not make measurement with the battery cover off.

6-2. Measurement

1) Push the power switch to ON of the both parts (CT & Body).

2) Set the range select switch to appropriate range to be measured (CT & Body).

3) Clamp CT to the conductor to be measured by pushing open/close guide.

4) In case of measurement in a dark place or in a place where it is difficult to

see the readings, use the data hold switch.

5) After measurement, draw out CT from the conductor.

6) Push the power switch to become OFF.

* If you want to make measurement continuously for long period, connect the

recorder by using φ2.5 pin jack at the terminal.

In this case, change the batteries to the new ones before measurement.

* When you make measurement to high voltage conductor, stretch the pipe before

the instrument. Do not draw the pipe too strongly. There is possibility for
pulling out the pipe, if you do it so much.

* The display value may not become "0" even when there is no input current
of the conductor but it is caused from the measuring method & design of
this instrument and such phenomenon will not effect on any accuracy of the
actual measurement value.

* Do not load any voltage to the terminal of recorder. It may destroy the instrument.

* The instrument may get heat and or damage if the over value current is
loaded to the CT. Do not load the current more than 600A.

* Avoid the measurement at the place where 2 wires contact with CT at the

same time.

* Do not touch other part of this instrument except grip of the body during

measurement.

6-3. Instalment/Replacement of Batteries

1) Confirm the power switch is OFF.

2) Remove the battery covers by the ◯

+

driver. (Be careful not to miss the

screw cap).

3) Install the batteries according to the indication of battery case.

4) Set up the battery cover and make the screws tightened firmly.

5) Put the screw cap on.
* Do not use the batteries by mixing new & old ones or used ones.

7. TESTING OF WITHSTANDING VOLTAGE

We recommend the testing if withstand voltage by loading 46KV for

1 minute between operation handle and core of CT once a year for the safety.
