• Displacement Polarity (Default Setting: Positive)
Positive: Displacement data is recorded and displayed indicating “positive” displacement
changes for positive voltage changes at the displacement sensor.
Negative: Displacement data is recorded and displayed indicating “negative” displacement
changes for positive voltage changes at the displacement sensor. Setting the
Displacement Polarity to Negative will invert the halfcycle graph displayed in the
halfcycle summary screen.
Displacement polarity should be set so that opening the electrodes will cause an increase in
displacement (when viewed using the Input Monitor screen, see Chapter 6) and closing the
electrodes will cause a decrease in displacement. This will ensure that Expansion and Set
Down are calculated properly.
• Avg. Null Cycles (Default Setting: No)
The weld monitor calculates average values for parameters within the weld segment. Within a
given segment there may be halfcycles in which there was no measured current, referred to as “null
cycles”.
No: The weld monitor calculates average values for the Segment and Weld Summaries using data
only from halfcycles in which there was measurable current within the weld segment.
Yes: The weld monitor calculates average values using data from all of the halfcycles in the weld
segment, including null cycles.
Note: The Avg. Null Cycles setting only affects values calculated from Current and Voltage. Force-
and Displacement-related calculations are not affected by this setting.
• Weld Type (Default Setting: AC)
This parameter should be set to the type of weld being monitored.
AC: The weld monitor is set to monitor single-phase AC welds.
All other settings are for use with a POD™ weld monitor and should not by used for WeldWise
2400 monitor operation.
• Weld History Depth (Default Setting: 100)
The Weld History Depth determines the number of welds displayed in the Weld Summary screen.
NOTE: Depending on the WeldWise™ 2400 software revision, other General Setup parameters my
appear on the screen. For ease of use and familiarity, the user interface portion of the software and the
databases used by the software are shared between some Livingston products. For this reason,
parameters used with other products may appear but will not be functional. Please contact Livingston
