Item Specifications
Voltage conversion Displays the estimated current converted with the preset supply
voltage (Conv Voltage), based on the voltage supplied to the EUT
and the measured current. (This is invalid in meter mode.)
Setting range 80.0 V to 300.0 V, OFF
Resolution 0.1 V
Power supply line polarity selection Set the polarity of the power supply line to supply to the EUT to
positive or negative.
Single fault mode (Condition) selection Set the EUT single fault mode to normal, neutral line disconnection
(Fault Neu), or protective ground wire disconnection (Fault PE).
Ground check In the touch current test between the enclosure and power supply
line, if the EUT enclosure is grounded, Contact-FAIL occurs.
Measurement check Checks the measurement function by shorting across the A and B
terminals. If an error is found, the protection function is activated.
