The ADD command may also be used to enter the 400Hz and 800Hz frequency
selection. Please reference the USB/RS232/GPIB section of the manual for additional
information regarding the ADD command.
NOTE : Due to increased leakage caused by the high frequency output of the
400/800 Hz waveforms, the SmartGFI feature may return a false failure at low
settings. Increasing the level of the SmartGFI detection parameter may be
required.
NOTE : 500VA models (8256/8257) may produce false arc failures at 800 Hz. In
order to prevent false failures, please set the Arc Level to 7 or less at output
current levels > 50mA
.
15 3mA AC/DC Output (Discontinued)
The 3 mA AC and DC Output option limits the Dielectric Withstand Test Mode output
current with software control. The trip points are adjusted to a maximum of 3 mA and
the software has been modified so the high-speed maximum current shutdown is fixed
at 3 mA.
The revised Dielectric Withstand Test Mode specifications are as follows
