1. INTRODUCTION

Electronic Digital Earth Resistance Tester is direct replacement of the

conventional hand generator type tester. It is designed for measurement

of the resistance of earthing used in the electrical equipment as well as

for measurement of soil resistance. It can be used for measurements of

the other low regular and liquid resistances. It can also be used for

measurement of voltage AC, voltage DC and resistance.

This instrument finds wide application for testing earthing installation in

power based industries, telecommunication networks and electrical

traction systems etc.

2. SAFETY INFORMATION

• Read the following safety information carefully before attempting to

operate or service the meter.

• To avoid damages to the instrument do not apply the signals which

exceed the maximum limits shown in the technical specifications tables.

• Do not use the meter or test leads if they look damaged. Use extreme

caution when working around bare conductors or bus bars.

• Accidental contact with the conductor could result in electric shock.

• Use the meter only as specified in this manual; otherwise, the protection

provided by the meter may be impaired.

• Read the operating instructions before use and follow all safety

Information.

• Caution when working with voltages above 60V DC or 30V AC RMS. Such

voltages pose a shock hazard.

• Before taking resistance measurements or testing acoustic continuity,

disconnect circuit from main power supply and all loads from the circuit.

3. SAFETY SYMBOLS

Caution refer to this manual before using the meter.

Dangerous voltages.

Meter is protected throughout by double insulation or reinforced

insulation.

When servicing, use only specified replacement parts.
