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 built-in test probes, an alligator clip,
a leatherette carrying case and batteries.
• 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
