| Output specifications | Output voltage : 25 V to 500 V, Setting resolution 1 V
Charging current
(Current limit function) : 50 µA to 50 mA*1*2*3, Minimum setting resolution 10 μA
Short-circuit current : 60 mA or less
Discharge current : 40 mA or greater
*1: Constraints involving the output generator will result in an error, making measurement impossible, if a capacitive load of approximately 50 μF or greater is connected while using a current limit setting of 5.1 mA or greater.
*2: When using a current limit setting of 5.1 mA or greater, measurement will be forcibly stopped if the output voltage is not at least 20 V at 200 ms after the start of measurement. Measurement will be possible 1 s after forcibly stopped.
*3: If the set current limit value is from 5.1 mA to 50.0 mA, the current will be limited to 5 mA after the output voltage reaches the set voltage. |
