simpson 501 Insulation Tester,

simpson's Model 501 is the newest addition to itsinsulation tester family. The Model 501 can be used for generalpurpose insulation tests that require voltages from 50 V to 1000 Vonly. Additionally, this instrument is equipped with AC and DCmeasuring ranges up to 1000 V. This is especially advantageous fortesting devices for the absence of voltage and the discharge ofcapacitive devices under test. The Model 501 features a quicktesting signal lamp within the test probe that serves to illuminatethe work area. The signal lamp can also be used for quick Pass/Failevaluations of insulation resistances. Minimum values forinsulation resistances are present if the lamp lights up. Eachtester comes equipped with built-in test probes, one alligatorclip, a leatherette carrying case and batteries.

• Five Test Voltages: 50, 100, 250, 500, and 1000VDC
• Voltage Measurement to 1000 V AC/DC
• Test Probe Signal Lamp Illuminates Work Area andIndicates Pass/Fail of Insulation Resistance
• Rugged Tester Design for Industrial Applicationswith Leatherette Carrying Case
• Battery Powered, with Battery Test and BatteryCharge Indicator
