*1 When tests are performed consecutively, output time limit and rest time may become necessary depending on the upper limit setting. *2 If an AC voltage is applied to a capacitive load, the output voltage may rise higher than at no load depending on the load capacitance. Further, waveform distortions may occur if an EUT whose capacitance is dependent on voltage (for example, an EUT that consists of ceramic capacitors) is connected as the load. However, if the test voltage is 1.5 kV, the effect of a capacitance of 1 000 pF or less can be ignored. Because the product’s high-voltage power supply uses the PWM switching method, if the test voltage is 500 V or less, the switching and spike noise proportions are large. The lower the test voltage, the greater the waveform is distorted.
Voltmeter
| Measurement range | 0.000 kV to 10.500 kV AC / DC |
|---|---|
| Resolution | 0.1 V |
| Accuracy | ±(1.2 % of reading + 5 V) |
| Response | Can be switched between true rms and mean-value response rms conversion. Peak-value response in a separate system (the peak-value response is for measuring the dielectric breakdown voltage while rising) |
| Hold function | The voltage measurement after a test is finished is held while the pass/fail judgment is displayed. |
Ammeter *1
| Measurement range | AC: 0.00 mA to 55 mA (Current including the active component and reactive component) DC: 0.00 mA to 22 mA |
|---|---|
| Accuracy | ±(1 % of reading + 2 μA) (active component) |

| Hold function | The current measurement after a test is finished is held while the pass judgment is displayed. |
| Offset cancel function | Cancels up to 10 mA of the current flowing through the insulation resistance and stray capacitance components across output cables and the like (resistance component only for DC tests). OFF function available. |
| Calibration | Active component: Calibrated with the rms of a sine wave using a pure resistive load. |
*1 During AC voltage tests, current also flows in the stray capacitance of items such as the test leads and tools.

|---|---|
| Voltage fall time setting time | 0.1 s to 200.0 s, OFF (valid only for determining PASS) During DC withstand voltage testing, the voltage may not fall entirely during the set time due to the internal capacitance and the capacitance of the test object. |
