m-4. EXTEND SETUP (4) Screen: FORCE (1/2)
(1) SCH.#
Shows the measurement schedule number used (1 to 127). On the other hand,
you can change schedules by selecting this field and inputting a value.
(2) Schedule name
Shows the name of SCH.#. This can be set in the BASIC SETUP (1) screen.
(3) OUTPUT LEVEL
You can output signals from external outputs FORCE LEV1, FORCE LEV2
and FORCE LEV3 if the measured value exceeds the set force level. There
are three input fields because you can specify three levels for a single
measurement and measure the force level at three locations. Set a force level
within the set measurement range.
(4) DELAY TIME
Set a delay time from the end of current flow to when the force measurement
interval or position is reached in the range from 0 to 1,000 ms.
Be sure that the total of the current flow time, the delay time (including the
cooling time between current flows), cooling time, and time to judge the current
flow end does not exceed the maximum current measurement range.
Make a measurement in a marginal range since the time to judge the current
flow end changed depending on the magnitude of the current.
A: Measurement of “FORCE FINAL”
B: Measurement range of “FORCE PEAK”, “FORCE AVG1” and “FORCE
AVG2”
C: Delay time
