ARC

If the ARC function is enable, the sign “*” means that there
is ARC during test.

CHANNEL
Hi: 00
Lo: 00

Set the Scanner Box to output and return function
through the setting of Hi and Lo. If the setting is
Hi=01 and Lo=02, that means the high voltage is
output from CH1 and return from CH2. If Hi and Lo
are set to 00, that means no signal is sent to Scanner
Box.

When the measured load becomes capacitive, the test time must be

extended.

Ramp Time

Ramp Time setting provides a fast and safe way to detect short circuit
or faulty wiring of your Device Under Test.

GPT/GPI-700A monitors the voltage level during the first stage of
Ramp Time to find out short condition. If the voltage still remains
less than 50V after 0.1s, GPT/GPI-700A cuts off the output and
displays the message “Short”. Therefore the short current will be shut
off before it grows beyond Imax, the current limit setting.

When checking GPT/GPI-700A current accuracy, if the DUT has less
than 2Mohm input impedance, turn off the Ramp Time setting.
GPT/GPI-700A may shut down the voltage taking the low impedance
as a sign of short circuit.
