[4] DESCRIPTION OF FUNCTIONS

4-1 Power and function switch

Rotate this switch to turn the instrument power ON/OFF and to select a

measuring range.

4-2 Data Hold function

When the button is pressed, the indicator lights on the display HOLD HOLD

and the current value is held displayed. The displayed value does not change

even when the measured input varies. Pressing the button again exits the hold

mode and returns the instrument to the measurement mode.

• The mode can also be exited when the range is switched.HOLD

4-3 MAX/MIN function

When the button is pressed, the instrument enters one of the MAX MIN MAX/

MIN modes, which is switched in the following sequence by every further press

of the button.

Maximum value display ( lit) MAX Minimum value display ( lit) MIN Current

value display ( blinking) MAX MIN Maximum value display ( lit) MAX ....

To exit the mode, press and hold the button for more than MAX/MIN MAX MIN

2 sec.

• The mode is also exited when the range is switched.MAX/MIN

4-4 Backlight function

Press the button lights the backlight of the display panel. Pressing the button

again extinguishes the backlight.

4-5 Auto Power OFF (APO)

When the APO function is enabled, the display turns OFF automatically in

about 15 minutes after the last operation to reduce the power consumption.

The indicator lights on the display when this function is enabled. To turn the

display ON again, press any button.

• A small amount of current is flowing even when the display is turned OFF by

the APO function. Be sure to set the Range switch to OFF after finishing

measurements.

•

To disable the APO function, turn the instrument ON while holding the

HOLD

button

depressed. The APO function is disabled when the indicator is not lit.

4-6 Low Battery indication

The indicator lights on the display when the supply voltage from the internal

batteries drops below about 2.3 V. If this indicator lights, replace the batteries

(both) with new ones.

[5] MEASUREMENT PROCEDURE

5-1 Start-up inspection

Check the following items before starting measurement.

• Appearance: Check that the exterior of the instrument is not damaged by

dropping it.

without wire disconnection or cracking of the cable coating.

• Check that the low battery indicator is not lit. If it is lit, replace the

batteries with new ones.

• Check that the instrument and your hand are not wet.

* If nothing is shown on the display after turning the instrument ON, the batteries

may be exhausted.

5-2 AC amperage (ACA) measurement

Always wear insulation protective gear such as rubber-insulated gloves.

[6] MAINTENANCE

6-1 Maintenance and inspection

1) Appearance:

• Check that the exterior of the instrument is not damaged by dropping it.

2) Cable between flexible CT and cabinet:

•

Check that the cable is normal without coating damage or exposed conductor.

3) Flexible CT:

•

Check that the white part inside the flexible CT is not exposed due to coating damage.

If any of the troubles above is found, do not use the instrument and call for service.

6-2 Calibration and Inspection

For more information, please contact Sanwa's authorized agent/distributor

service provider, listed in our website. See section 7-3.

6-3 Storage

1. The panel and case are not resistant to volatile solvent and must not be

cleaned with thinner or alcohol.

2. The panel and case are not resistant to heat. Do not place the instrument

near heat-generating devices (such as a soldering iron).

Do not store the instrument anywhere it may be subject to vibrations or could fall.

4. When storing the instrument, avoid hot, cold or humid locations, locations

exposed to direct sunlight, or locations where condensation is anticipated.

5. When the instrument is not going to be used for an extended time, be

sure to remove the batteries.

CAUTION

6-4 Battery Replacement

• The battery loaded at the factory is a monitor battery, so their service life may

be shorter than that of a brand-new battery. A monitor battery is a type of

battery used to check the functions and performance of a product.

• To prevent the risk of electric shock, do not remove the battery compartment

cover while the flexible CT is clamped around the measured conductor.

1. It is hazardous to use the flexible CT with a conductor in the live state. Be

sure to wear insulation protective gear such as rubber-insulated gloves

before clamping or unclamping the flexible CT.

2. Do not use the instrument if the coating of the flexible CT is damaged and

the internal white part is exposed.

3. Do not use the instrument with a line with voltage to ground over 600 V.

WARNING

1. To reduce the measurement errors, position the measured conductor

(wire) as close as possible to the center of the flexible CT.

Always clamp around a single wire at a time. Correct current

measurement

is impossible if multiple wires, for example two single-phase and three

3-phase lines, a cable with multiple conductors or parallel cords are

clamped.

3. Correct measurement may sometimes be impossible near a source of

strong magnetic field, such as a transformer or high-current path, a

source of electromagnetic wave or a charged object.

CAUTION

1. The section is very important for safety. Read and understand the

following instructions fully and maintain your instrument properly.

2. For securing safety and accuracy, inspect and calibrate the instrument at

least every year.

WARNING

1. Using a Phillips screwdriver, remove the fixing screw

(x 1) from the battery compartment cover.

2. Replace both of the two batteries in the battery holder

with new ones by taking care of the polarity.

3. Place the battery compartment cover and tighten the

fixing screw.

1.Set the Range switch to the desired

measuring range. If the measured current

value is unknown, begin with the 3000 A

range and decrease it sequentially as

required.

2.Clamp the flexible CT around the conductor

so that this is positioned vertically on the

center of the flexible CT.

3.Read the value on the display.
