Inspecting before Measurement and Verifying Operations
Checking the voltage generated
Check that operations are at an environmental temperature of 23 C±5 C, and that the humidity is
80% RH or less.
1
Select an empty table to which nothing has been saved in the test conditions settings mode.
2
Set the applied voltage to 100 V, the sampling frequency to 200 MHz, the number of sampling
data to 1001, and the number of pulses to be applied to 1.
3
Implement the tests with nothing connected to the voltage output terminal.
(Illustration below is ST4030A)
Rear
(Nothing is connected)
4
Check that the peak voltage (value displayed on the instrument) is 100 V ±2%.
5
Change the voltage setting.
ST4030: 3300 V
ST4030A: 4200 V
6
Implement the test with nothing connected to the voltage output terminal.
7
Check that the peak voltage (value displayed on the instrument) is below.
ST4030: 3300 V±2%
ST4030A: 4200 V±2%
IMPORTANT
Contact your authorized Hioki distributor or reseller if the peak voltage differs from the set voltage by 2% or
greater.
