12501 Simpson

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 Ordering Information Accessories Catalog Number 501 Insulation Tester, 1000V 12501 1 Rev. 04-15501 Insulation Tester Measuring Ranges Insulation Resistance Measuring Open-Circuit Internal Lamp in Test Prod Range Voltage U Resistance R Lights for Resistance (1) 0...50K 30K 20K...1M 60V 10K > 100K 200K...20M 40K 0...100K 60K 40K...2M 120V 20K > 200K 400K...40M 80K 0...250K 150K 100K...5M 300V 50K > 500K 1M...100M 200K 0...500K 300K 200K...10M 600V 100K > 1M 2M...200M 400K 0...1M 600K 400K...20M 1200V 200K > 2M 4M...400K 800K 0...4K 9V - - (1) Switching Accuracy Direct and Alternating Current Measuring Internal Maximum Intrinsic Range Frequency Resistance Overload Error (1) 0 to 1000V AC/DC 0 or 40 to 200Hz 900K 1200V AC/DC Continuous 2.5% (1) Referring to scale length Specifications subject to change without notice 2 Rev. 04-15
