TOS1200泄漏电流测试仪
Calibration of Leakage Current Detection Sensitivity
Direct Reading of Error from Error Display Scale
Ammeter Ranges
Eliminates Need for Power Supply
AC/DC Selection Switch
Measuring Function Measurement of current values and  error (%) for AC (50/60 Hz) and DC at a test voltage of 1000 V
Measuring Ranges 8 ranges consisting of 0.5/1/2/5/10/20/50/100 mA along with values equal to 0.8 times the values of  those ranges (for 1, 2, 4 and 8 steps)
Ammeter Scale Main scale: Direct-reading errordisplay scale over a range of ±10%of the above full scale values Auxiliary scale: Ratio scale of 0 to1.1 times the above full scale valuesAccuracy:
(equivalent to 0% display of mainscale when the ratio is equal to 1)
Ammeter Accuracy Main scale: ±1% of reading  Auxiliary scale: ±3% of full scale value
Ammeter Indication DC/AC(sine wave rms value  calibration of mean value response)
