Withstanding Voltage Tester, TOS Series

High-end model of TOS series having AC, DCa10kV output.

TOS series (TOS5101/TOS5051/TOS5050) are designed exclusively for withstand-voltage testing of electronic equipment and components conforming to various safety standards. The use of a high luminance, large fluorescent display tube for the display enables data including measured values, status and judgment results to be extremely legible. The Pass/Fail function employs a window comparator method that enable TOS5101m to make fail judgment of current leakage over the upper reference value and below the lower reference value which can be set on the front panel.

Thus, highly reliable testing can be performed including that for test lead disconnection and defective contact. In addition, in order to prevent erroneous operation and accidents, the TOS5101 is also equipped with a Key Lock function and Interlock function, a high-voltage output terminal having a narrowed insertion port, a large DANGER lamp, and an automatic discharge function (during DC operation) that removes charge from the test piece. These features give the TOS5101 a high degree of safety and reliability.
