2 Instrument features
This instrument has been manufactured complying with Quality Assurance System DIN
ISO 9001. The compliance with the current applicable EMC-regulations is indicated by
the CE-sign and markings on the instrument.
Two instruments in one hand-held housing:
- Compact and universal insulation tester
- Industry standard TRMS multimeter
The instrument has been designed specially for contractor/service technician
applications. In addition to insulation testing up to 1 kV the instrument
incorporates low resistance and continuity testing as well as leakage current
measurement directly or with LEM current probes (CT's). Selectable scaling
factors provide current ranges from 200µA to 200 A. Furthermore the
instrument offers all the functionality of industry standard multimeters
including TRMS voltage and frequency measurement in a true hand held
design.
Main features:
• Easy to use handheld design measuring V, Ω, MΩ, Hz, A (mA)
• Large dual display with bright EL backlight and bargraph
•
Unique built in protection against external voltages without fuse damage and
warning of live circuits
• Fully compliant with all European standards for insulation testing
• Insulation measurements up to 20 GΩ with 100, 250, 500 and 1000V test
voltages and display of test current
•
On screen display of Polarisation Index and Dielectric Absorption Ratio for
insulation quality
• Auto ranging resistance measurement to 200kΩ with 200mA low resistance test
and lead compensation
•
Continuity test with adjustable thresholds and fast responding buzzer
•
True RMS voltage measurement with display of AC, DC and AC+DC values and
mV resolution
• Leakage current measurement directly or with LEM current probes in current
ranges from 200 µA to 200A
•
LIMIT (adjustable alarm) to quickly and reliably identify fault conditions
•
REC function for MIN, MAX, AVG values
• ZERO (∆REL) function to compensate measuring leads and for relative
measurements
