“CROWN” made DIGITAL MICRO OHM METER -53C  is a compact high reliability 3 ½ digit instrument suitable for measurement of resistivity of copper wires from 70 SWG to 50 SWG resistance of cables , windings , coils , heater elements & contact resistance of switches , relays etc. Emphasis in the design of this instrument has been to provide quick , stable & repeatable readings of resistance . The instrument uses 4 terminal measurement so that resistance of test leads & contacts in eliminated from test results . Actual value of resistor is directly displayed on seven segment 12.5mm display.
