501 Insulation Tester
The model 501 can be used for general purpose insulation tests that require voltages from 50V to 1000V only.
The Instrument is equipped with AC and DC measuring ranges up to 1000V. This is advantageous for testing for the absence of voltage and the discharge of capacitive devices under test.
The 501 features a quick testing signal lamp within the test probe that illuminates the work area. The signal lamp can also be used for quick Pass/Fail evaluations of insulation resistances. Minimum values for insulation resistances are present if the lamp lights up.
Comes equipped with
•Five Test Voltages: 50, 100, 250, 500, and 1000 VDC
•Voltage Measurement to 1000 V AC/DC
•Test Probe Signal Lamp Illuminates Work Area and Indicates Pass/Fail of Insulation Resistance
•Battery Powered with Battery Test and Battery Charge Indicator
•Rugged Tester Design for Industrial Applications with Leatherette Carrying Case
