• ALL PULSE (SET)
Used when current is passed several times in a single welding sequence
and the number is decided.
The instrument makes measurement of a number of times specified in PULSE
No. in a single welding sequence as a single sequence.
When the number of current flow times of PULSE No. has been measured, a
current measurement ends regardless of the delay time setting of
displacement, force and external.
If the number of current flow times is less than the times specified by PULSE
No., the impulse error occurs in the time that current is not passed after the
maximum current measurement time elapses.
(Note) In ALL PULSE (SET), set PULSE No. to the same value as the number
of current flow times in a single welding sequence.
Measurement schedule and judgment schedule
You need to set measurement schedule and judgment schedule from SCH.# of
the measurement start to SCH.# of the number of current flow times. As for
measurement schedule, make all SCH.# to use the same. As for judgment
schedule, the schedule numbers following the schedule number of
measurement start are assigned for measurement schedule, for example, first
step to the schedule number of measurement start, second step to the start
schedule number +1...
Ex.: When making measurement schedules for SCH.#003 to 007 contents in
the BASIC SETUP (1) and (2) screens and the EXTEND SETUP (1), (4) and
(6) screens the same and measuring the 3-step welding with SCH.#003
Input the judgment schedule of the first step to SCH.#003
Input the judgment schedule of the second step to SCH.#004
Input the judgment schedule of the third step to SCH.#005
1) When current is first measured, and displacement, force or external input is
NOT measured
a: WELD b: COOL
When PULSE No. is set to 3, the first to third steps are measured and then
ended. The fourth step is not measured.
(Note) For measurable time, refer to “Measurable time of all-pulse
measurement for each mode.”
