The ohmmeter of ES0212 is intended for measurement of electrical resistance of the grounding wiring, establishment of the fact of its break on value of electrical resistance and detection of alternating current voltage on the equipment at isolation violation. The ohmmeter of ES0212 is the improved analog of M372.
In an ohmmeter the parallel scheme of measurement of resistance with use of the microampermeter of magnetoelectric system with a loose port on extensions is applied.
Measurement range is from 0, 05 Ohm to 20 Ohms.
Accuracy rating - 1, 5 in accordance with GOST 23706 - 93.
Length of a scale, not less than 88 mm.
The ohmmeter has two operating modes:
- an availability verification regime on object of strain measurement of alternating current from 0 to 380 V;
- the mode of measurement of resistance in the range from 0, 05 Ohm to 20 Ohms.
A power supply of an ohmmeter from chemical sources of a direct current (R6, LR6 element) with a rated voltage of 1, 5 V.
Current of consumption, no more than 30 mA.
- ambient air temperature from minus 30 °C to plus 50 °C;
- relative air humidity to 90% at a temperature plus 25 °C.
Weight, ohmmeter no more than 1, 0 kg.
Leading dimensions of 150 mm x 70 mm x 200 mm.
