Digiatal Micro Ohm Meter
CROWN Digital Micro Ohm Meter is a compact high reliability 3 1/2
Digit instrument suitable for measurement of resistivity of copper
wires from 7/0 SWG to 50 SWG. resistance of cables, windings, coils,
heater elements and contact resistance of switches, relays etc.
Emphasis in the design of this instrument has been to provide quick,
stable and repeatable readings of resistance. The in strume ntsuses 4 -
terminal me asurement so tha tresistanc eoftest leads and contacts is
eliminated from test results. Actual value of resistor is directly
displayed on seven segment 12.5mm Display.
Specification
RANGE OF MEASUREMENT : 1micro-ohm to 1999 ohm in seven range.
