Ohmmeter M372 (M-372, M 372)
Ohmmeter M372 is designed to measure the resistance grounding wiring determine whether its failure, and also to detect an emergency voltage equipment.
The movable part of the instrument is made from wires.
Technical characteristics of the devices Ohmmeter M372:
Ambient temperature - from -30 º C to +40 º C;
Relative humidity - 90% at a temperature of 30 º C;
Accuracy class of the device - 1.5;
Ohmmeter M372 allows measurement of the resistance to 50 ohms, and detect the presence of AC voltage from 60V to 380V;
Measuring mechanism ohmmeter placed in a plastic case and is completely enclosed. Housing cover with a lid. It reinforced belt that is used to carry the device. Connecting the M372 ohmmeter to the measured object is made using a special probe and clamp with flexible conductor resistance of 0.035 ohms;
The instrument has two scales:
1) calibrated to 50 ohms with a measurement range from 0.1 ohms to 20 ohms;
2) the non-graded scale voltage with the inscription: "the presence of voltage 60V-380V";
Dimensions of the device ohmmeter M372 - 190h135h72mm;
Weight - 1.3 kg.
