This is a drop time measurement function THAT DOES
AN ACTUAL WELD. If F48 (Drop Time Configuration) is
in either Manual or Auto mode, the measurement taken
during the weld (while viewing this function) will be stored
in this function and used in weld timing. The measured
value may be overridden by using the arrow keys. This
value changes automatically depending on F30 (short
cycle mode) and the gun interface installed in the unit.
