Start voltage

 

The voltage at the start of the test can be set.

Setting range

1 % to 99 % of the test voltage (1% resolution)

Output voltage monitor function

If the output voltage exceeds ±(10 % of setting + 0.05 kV), the output is turned off, and the protection function is activated.

\*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)

Response

Can be switched between true rms and mean-value response rms conversion.

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.

### Judgment feature

Upper limit setting range

AC: 0.01 mA to 55.00 mA, DC: 0.01 mA to 21.00 mA

Lower limit setting range

AC: 0.00 mA to 54.99 mA, DC: 0.00 mA to 20.99 mA, OFF.  
Setting 0.00 is equivalent to OFF.

Judgment accuracy \*1

±(1 % of setting + 5 μA)

Current detection method

Comparison with reference values using the following methods:  
Calculating true RMS value / Converting the average response to RMS value / Measuring the wave height.

Response speed (filter)  
switching

Switches the current detection response speed (sensitivity) used in UPPER FAIL judgment between five levels in ACW and DCW tests.

\*1 During AC voltage tests, current also flows in the stray capacitance of items such as the test leads and tools.

### Timer function

Voltage rise time settings range

0.1 s to 200.0 s

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.

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 (DCW only)

Accuracy

±(100 ppm of setting + 20 ms) (excluding the 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.
