Description
The ISO plus has been designed specially for contractor and service technician applications. In addition to insulation testing up to 1 kV the ISO plus incorporates low resistance and continuity testing as well as leakage current measurement directly or with Fluke current probes (CT’s). Selectable scaling factors provide current ranges from 200ìA to 200 A. Furthermore the ISO plus offers all the functionality of industry standard multimeters including TRMS voltage and frequency measurement in a true hand held design.

This unique combination satisfies universal applications in: Insulation measurement up to 20GΩ with test voltages of 100V, 250V, 500V and 1000V.

Low-resistance measurement according to EN 61557-4 with a shortcircuit current of >200mA, (50mA can be selected to extend battery life) for applications with non-fused earth conductor connections and equipotential bus bars.

Fast continuity testing with selectable buzzer threshold between 0.2 Ω and 50 Ω and a maximum response time of 100ms meeting all test standards.

Leakage Current measurement through an external current transformer with selectable transformer ratio from 1:1 up to 1:1000 and ranges from 200ìA to 200A.

Voltage measurement with display of AC and DC values up to 600V with an 800V overrange feature.

With additional functions including ZERO (test lead null / relative), REC (Min, Max, Avg) and LIMIT (Alarm), the ISO plus provides a complete measurement solution in one compact handheld instrument.
