W/I Auto Tester

Withstanding Voltage Tester: AC 5 kV/100 mA

The Model TOS8850A is an automatic tester equipped with a withstanding voltage tester and insulation resistance tester that is able to perform withstanding voltage testing and insulation resistance testing continuously. (Available settings include AUTO W-I, AUTO I-W, MANU.W and MANU. I.)

The withstanding voltage tester section has a maximum output of 5 kV and maximum capacity of 500 VA (AC use only). Withstanding voltage tests can be performed on electronic equipment and electronic components. In addition, the insulation resistance tester section is equipped with two measuring ranges of 500V/1000 MOhm and 1000V/ 2000 MOhm.

Functions include Pass/fail judgement, output of judgement result and status signal and remote control. The Pass/fail judgement function employs a window comparator type that can be used to detect test lead disconnections and defective connections in both withstanding voltage and insulation resistance tests. In addition, the use of judgement result and status signal output along with the remote control function result in a significant improvement in testing automation and efficiency.
