2.9 Startup Inspection
To ensure safe testing, check the following before starting operation:
(1) Breaking current (withstand voltage mode)
1. Calculate the resistance based on the output-voltage set for withstand
voltage testing and the upper test value, and prepare a resistor
corresponding to the calculation result.
(Output voltage Upper-limit value (Breaking current) = Resistance)
2. Set an upper-limit value.
3. Connect the resistor to the H.V. TEST LEAD.
4. Increase the output voltage beyond the set value, and make sure the
current is cut off (i.e., make sure the unit is in the FAIL state).
(2) Measured resistance (insulation-resistance mode)
1. Calculate the resistance based on the test voltage set for insulation
resistance testing and the measured current (1 mA), and prepare a resistor
whose resistance is larger than that of the calculation result.
output-voltage measured current (1 mA) resistance value)
2. Specify the test voltage.
3. Connect the resistor that you prepared to the H.V. TEST LEAD.
4. Make sure that the resistance measured matches the resistor that you
prepared.
(3) Analog voltmeter
1. Before turning on the power, make sure the analog voltmeter is at 0 kV.
2. If the voltage reading is not at zero, adjust the value to zero using a
slotted screwdriver.
(4) Interlock
If the Interlock function is set, make sure the Interlock function works
properly before starting operation. (See Section 8.1.4)
