1. General introduction
1.1. Features
The TeraOhm 5kV Tester is a portable battery / mains powered test instrument intended
for testing of Insulation Resistance by using high test voltages of up to 5 kV. It operates
on a SIMPLE and CLEAR basis.
The instrument is designed and produced with the extensive knowledge and experience
acquired through many years of dealing with similar test equipment.
Available functions offered by the TeraOhm 5kV Tester:
• High Insulation Resistance measurement up to 5 T Ω
- Programmable test voltage 250 V up to 5 kV
- Programmable timer 1s up to 30 min
- Automatic discharge of tested object after measurement completion
- Capacitance measurement
• Insulation Resistance measurement versus test voltage (step-up voltage)
- Five discrete test voltages proportionately set within preset test voltage range
- Programmable timer 1min up to 30 min per step
• Polarization Index PI and Dielectric Discharge ratio
- PI = RINS (t2) / RINS (t1)
- DD = Idis (1min) / C ⋅ U
• Withstanding voltage (DC) up to 5.5 kV
- Programmable ramp test voltage 250 V up to 5 kV
- High resolution ramp (approx. 20 V per step)
- Programmable threshold current
• Voltage and frequency measurement up to 600 V AC/DC
A dot matrix LCD offers easy-to-read results and all associated parameters. Operation is
simple and clear; the operator does not need any special training (except reading and
understanding this Users Manual) to operate the instrument.
The instrument allows storage of test results. Professional PC SW enables simple
transfer of test results and other parameters in both directions between the test
instrument and PC.
