Inspection and Maintenance

Initial Inspection

When you receive the product, inspect it carefully to ensure that no damage occurred during shipping. If damage is evident, or if it fails to operate according to the specifications, contact your dealer or Hioki representative.

Preliminary Checks

Before using the product the first time, verify that it operates nor-mally to ensure that the no damage occurred during storage or shipping. If you find any damage, contact your dealer or Hioki representative.
Before using the product, make sure that the insulation on thecables and the protective tube of the fuse holder is undamaged and that no bare conductors are improperly exposed. Using the product in such conditions could cause an electric shock, so contact your dealer or Hioki representative for repair.

Maintenance and Service

To clean the product, wipe it gently with a soft cloth moistened withwater or mild detergent. Never use solvents such as benzene, alcohol, acetone, ether, ketones, thinners or gasoline, as they can deform and discolor the case.
To verify that the product operates normally, connect the tester to athree-phase power supply that has a collect phase order and make sure that the indicator dial rotates in the direction of the arrow.
If the product seems to be malfunctioning, your dealer or Hioki rep-resentative. Pack the product carefully so that it will not be damaged during shipment, and include a detailed written description of the problem. Hioki cannot be responsible for damage that occurs during shipment.

Usage Notes

This manual contains information and warnings essential for safe operation of the product and for maintaining it in safe operating condition. Before using the product, be sure to carefully read the following safety notes.

The maximum rated working voltage is 480 VrmsAC. Attempting to measure voltage in excess of the maximum rating could destroy the product and result in personal injury or death.

To avoid electric shock, do not allow the product to get wet, and do not use it when your hands are wet.
To avoid electric shock when measuring live lines, wear appropriate protective gear, such as insulated rubber gloves, boots and a safety helmet.
Do not use the product where it may be exposed to corrosive or combustible gases. The product may be damaged or cause an explosion.
To avoid electric shock, turn off the power before attaching a clip, and then turn on the power to measure.

Do not store or use the product where it could be exposed to direct sunlight, high temperature or humidity, or condensation. Under such conditions, the product may be damaged and insulation may deteriorate so that it no longer meets specifications.
To avoid damage to the product, protect it from vibration or shock during transport and handling, and be especially careful to avoid dropping.

NOTE

Continuous use for long periods of time may be dangerous. Be sureto use the tester within the maximum permissible use times given above.
If the power voltage is unknown, be sure to check it first with a volt-meter before connection the tester.
This tester is designed to be used in the horizontal position (±15°). Using it in other attitudes may prevent the dial from rotating, and cause faulty readings.

Features

The ABS case and all movable components are resistant to vibration and impact, providing the strength needed for field application. And its compact size and light weight provides superior portability. In addition, the leads are color-coded to match the dial, making it easy to tell R, S and T leads from each other.

Measurement Procedure

Connect the tester to a three-phase circuit. If the circular dial rotates in the direction of the arrow, the phase connection order is RST.
Measurement Procedure - Connection

Fuses are contained in the fuse holders.

Fuse Replacement

To avoid electric shock when replacing the fuse, first disconnect the clip from the object to be measured.
Replace the fuse only with one of the specified characteristics and voltage and current ratings. Using a non-specified fuse or shorting the fuse holder may cause a life-threatening hazard. Fuse type: 7012540 (made by SIBA Inc.), Rating FF0.5 A/700 V (non-arcing) 6.35 X 32 mm dia.

The leads on the clip side of the fuse holders do not rotate turn independently of the fuse holders. To avoid damaging the leads, do not turn the fuse holders unless the leads are free to turn with them.

Open the fuse holder by turning one end counterclockwise.
Replace the fuse inside the fuse holder.
Close the fuse holder by pushing the ends back together, then turning one end clockwise.

Warranty

Warranty malfunctions occurring under conditions of normal use in conformity with the Instruction Manual and Product Precautionary Markings will be repaired free of charge. This warranty is valid for a period of one (1) year from the date of purchase. Please contact the distributor from which you purchased the product for further information on warranty provisions.
