12505产品概述
Model 501:
The Model 501 can be used for general purpose insulation tests that require voltages from 50 V to 1000 V only. Additionally, this instrument is equipped with AC and DC measuring ranges up to 1000 V. This is especially advantageous for testing devices for the absence of voltage and the discharge of capacitive devices under test. The Model 501 features a quick testing signal lamp within the test probe that serves to illuminate the work area. The signal lamp can also be used for quick Pass/Fail evaluations of insulation resistance. Minimum values for insulation resistance are present if the lamp lights up. Each tester comes equipped with built-in test probes, one alligator clip, a leatherette carrying case and batteries.
Model 505:
Simpson's Model 505 High Voltage Insulation Tester is capable of measuring insulation resistance from 10 kΩ to 1 TΩ with eight selectable test voltages up to 5000 V. As a safety feature, the insulation tester acts as an AC/DC voltmeter to measure the absence of voltage in networks up to 2000 V. The cables are permanently attached, preventing possible injury that could occur by the accidental removal of the cables. An optional guard terminal is available to minimize surface leakage errors. Each tester comes in a padded carrying case with permanently connected cables and test probes, 2 alligator clips and a plug-in battery module with batteries.
