پل اندازه گيري مقاومت مدل 18C (پل وتســــون) مدل 18C

MetrOhm OhmMeter 18C Fault Locator
The Ohmmeter 18C is specially designed to meet the needs of the telecommunications installation and maintenance engineer for a wide range of cable fault tests particularly on local telephone networks.
The Ohmmeter 18C can be used for a wide variety of cable fault tests. Insulation tests can be made at either 95V or 500V, with direct readings in Megohms. Conductor resistance tests may be made, including loop resistance, single wire resistance, and location of earth or contact faults. Disconnexion tests are made using the RHEOSTAT BALANCE scale on the meter.
* Removable lid for increased accessibility
