Setup notes
•Mode should be set to the type of welding current –AC or DC.
•Frequency should be set to the supply frequency – 50 or 60 Hz (AC welding only).
•DCthreshold readings below this percentage of the maximum current will be excluded from
the RMS and duration calculations (DC welding only).
•PrintviaPC
off – no printing; all – prints every ½ cycle (AC) or 10 ms (DC) reading; summary – prints
average current and duration for each weld pulse.
USBdriver – www.ftdichip.com/Drivers/VCP.htm
•Blankingis the number of cycles/ms after the start of the weld that will be excluded from the
RMS calculation.
•Range determines the maximum current that can be measured.
•Auto shutdown enables or disables power saving mode.
•Stop after nn cycles/ms can be used to capture a specific section of a long weld. If the weld
is longer than this parameter, a symbol will be shown alongside the weld time.
