Metravi Digital Micro Ohm Meter is a Compact High Reliabilty 3½ Digit Instrument Sutaible For Measurement of Resistivity of Copper Wires From 7/0 Swg to 50 Swg. Resistance of Cable, Winding, Coil, Heater Element and Contact Resistance to Switches, Relays ect. Emphasis in The Design of This Instrument Has Been to Provide Quick, Stable And Repeatable Reading of Resistance. The Instruments Uses 4-Terminal Measurement so That Resistance of Test Leads And Contacts is Eliminated From Test Results. Actual Value of Resistor Directly Displayed on Seven Sigment 12.5 Mm Display.
