Kikusui TOS1200 Withstanding Voltage Tester Current Calibrator

• Model TOS1200 Withstanding Voltage Tester Current Calibrator: For calibration of current sensitivity of withstanding voltage testers
• Calibration of Leakage Current Detection Sensitivity As a result of containing an internal test load resistor, the TOS1200 enables switching of ammeter sensitivity and load resistance values automatically for easy calibration of the sensitivity of leakage current detection
• Direct Reading of Error from Error Display Scale. The main scale consists of an error display scale ranging from -10% to +10% around a central full scale value. Thus, if the leakage current detection sensitivity of the withstanding voltage tester is a value of 1, 2 and 5 steps or 1, 2, 4 and 8 steps, the error can be read directly from the scale. The auxiliary scale consists of a ratio display scale in which the full scale value is taken to be 1.1, thereby enabling accommodation of values outside the range of the main scale
• Ammeter Ranges The ranges of the ammeter consist of 0.5, 1, 2, 5, 10, 20, 50 and 100 mA, and values equal to 0.8 times those values can be set. This is convenient for withstanding voltage testers of the type in which leakage current detection sensitivity is set digitally (1, 2, 4 and 8 steps)
• Eliminates Need for Power Supply The TOS1200 offers outstanding portability since it does not require a power supply
• AC/DC Selection Switch
