The Appa 605 digital insulation resistance, handheld tester measures insulation resistance from 10 kΩ to 20 GΩ with test voltages selectable from 50, 100, 250, 500 and 1000 DC. Resistance can be measured from 0.01 Ω to 20 kΩ. Polarisation index and absorption ratio are calculated automatically. The instrument is also usable as an accurate multimeter for measuring voltages to 600 AC/DC and resistance.
The unit has a 4000-count digital display and a 48-segment bar graph. Insulation resistance is measured with a resolution of 0.01 MΩ. Low resistance measurements are made with a resolution of 0.01 Ω including earth bond resistance. The voltmeter will indicate live circuits.
The tester is equipped with store/recall memory and comparator functions and auto power-off. The instrument is provided with a remote test probe, test leads, alligator clips and magnetic hanging kit.
It complies with Cat IV 600 V and Cat III 1000 V standards. The alkaline batteries supplied provide an average life of 200 hours.
