Features:

• AC Automatic Insulation/Withstanding Tester
• 3174 AC Automatic Insulation/Withstanding Tester
• Continuous testing of insulation (500/1000 V) and withstand voltage (100 VA transformer capacity)
• Full remote operation when used in combination with the Safety Test Data Management Software 9267
• Save up to 8 test settings each for the withstanding and insulation testing modes
• Precise test voltage without power voltage dependency is generated using the PWM method
• Carry out standards-based tests with simple operations
• Saving and loading test conditions
• Automatically carry out consecutive withstanding and insulationresistance tests
• Contact check function to increase testing reliability
• Real execution value shown
• Cutting out influence from supply voltage fluctuations
• Continuation of testing even after test failure makes analysis of sample possible

Inaccuracies in measurements have been noted to occur during the withstandvoltage and insulation-resistance tests because of variations in the test voltage caused by fluctuations in the voltage supply, breaking of the test leads and improper connection.Model 3174, 3174-01 AC Automatic Insulation/Withstanding HiTester is an affordable insulation/withstanding testing instrument equipped with stable voltage supply and contact check functions to prevent a decrease in testing reliability caused by these factors.In addition, to improve the efficiency of the testing process on the production line, it allows testing settings to be retrieved from both RS-232C (GP-IB) as well as EXT I/O.
