This correction also affects the measurement of TRIGGER LEVEL to start
measurement of force. When setting OFFSET, also review the TRIGGER
LEVEL setting.
(6) DECIMAL RANGE
When you have selected RATED SETTING1 or RATED SETTING2 for
SENSOR, set a decimal point as follows: **.**, ***.*, ****
(7) UNITS
Select the force unit used for settings and display related to force from N, kgf,
and lbf.
When the UNITS setting is changed, RATE may be initialized. Set RATE
again.
(8) TRIGGER LEVEL
Set a trigger level (1.0 to 99.9%) as the percentage of full scale. A force is
measured while it exceeds the trigger level.
Set it to 99.9% when performing measurement according to the current
measurement start.
(9) INITIAL MEASUREMENT
Select CURRENT START or EXTERNAL INPUT.
CURRENT START: The force before welding is measured when the WE1
starts.
EXTERNAL INPUT: When the MEAS BEFORE WELD input signal (refer to (1)
in “o-1. EXT INPUT/OUTPUT (1) Screen”) is received, the force before welding
is measured. After measurement, judgment of the output before welding can
be set.
