Output
| Output voltage range | -25 V to -1000 V/+0.05 kV to +10.000 kV | |
|---|---|---|
| Resolution | 1 V | |
| Setting accuracy | ±(1.2 % of setting + 2 V)/ ±(1.2 % of setting + 0.02 kV) | |
| Max. rated load | 1 W (-1000 V/1 mA)/10 W (10 kV/1 mA) | |
| Max. rated current | 1 mA | |
| Ripple | 1 kV no load | 2 Vp-p or less/30 Vp-p or less |
| Max. rated load | 10 Vp-p or less/70 Vp-p or less | |
| Voltage regulation | 1 % or less (when changing from maximum rated load to no load) | |
| Short-circuit current | 12 mA or less/As per DCW specifications | |
| Discharge function | Forced discharge after test completion (discharge resistance: 20 kΩ)/As per DCW specifications | |
| Output voltage monitor function | If the output voltage exceeds ±(10 % of setting + 50 V), the output is turned off, and the protection function is activated. | |
Voltmeter (Digital *1)
| Measurement range | Negative polarity: 0 Vdc to -1200 Vdc Positive / polarity: 0 kVdc to 10.500 kVdc |
|---|---|
| Resolution | 0.1 V |
| Accuracy | Negative polarity: ±(1 % of reading + 1 V) Positive polarity: ±(1.2 % of reading + 5 V) |
*1 When positive polarity is outputted, it conforms to the voltage tester’s voltmeter specifications.
Resistance meter
| Measurement range | 0.001 MΩ to 100.0 GΩ (in the range of maximum rated current of 1 mA to 5 nA) |
|---|---|
| Hold function | The resistance measurement after a test is finished is held while the pass judgment is displayed. |
| Offset cancel function | Cancels up to 2000 GΩ of the unnecessary insulation resistance across output cables and the like. OFF function available. |
Judgment feature
| Upper limit setting range | 0.001 MΩ to 100.000 GΩ (in the range up to the maximum rated current), OFF |
|---|---|
| Lower limit setting range | 0.000 MΩ to 99.999 GΩ (in the range up to the maximum rated current), OFF. Setting 0.000 is equivalent to OFF. |
| Judgment Accuracy For Both UPPER and LOWER | Add ten digits to the resistance measurement accuracy. (An evaluation waiting test time and test time of 3.0 s or longer are required for evaluations of 200 μA or less and 10.0 s or longer when LPF is set to ON.) |
Timer function
| Voltage rise time settings range | 0.1 s to 200.0 s |
|---|---|
| Test time setting range | 0.1 s to 1000.0 s, OFF |
| Judgment delay (Judge Delay) setting range *1 | 0.1 s to 100.0 s, AUTO |
| Accuracy | ±(100 ppm of setting + 20 ms) (excluding Fall Time) |
*1 Less than the sum of the rise time and fall time. *2 When “Delay Auto” is set to ON, UPPER determination will not be performed until the charging time ends.
