1. General introduction
1.1 Features
The GigaOhm 1kV is a portable hand-held battery powered test instrument intended for
testing of safety measures on mains installations.
The equipment is designed and produced with the extensive knowledge and experience
acquired through many years of dealing with electrical installation test equipment.
General functions of the GigaOhm 1kV:
- Insulation resistance measurement,
- Continuity measurement using test current of 200 mA in accordance with EN 61557-
4 standard,
- Continuity measurement (continuous measurement) using test current of up to 7 mA,
- AC / DC voltage measurement.
Features:
- Insulation resistance test voltages: 250 V DC, 500 V DC, 1000 V DC,
- Automatic discharge of tested item after measurement completion,
- Automatic test voltage polarity exchange in Continuity 200 mA function,
- Rcon 7 mA function for inductive test items.
A custom designed LCD offers easy to read results. Operation is simple and clear, the
operator does not need any special training (except reading and understanding this
User Manual) to operate the instrument.
In order for the operator to be familiar with measurements in general, it is advisable to
read the handbook Measurements on electric installations in theory and practice.
