Threshold Value Fine Adjustment Function - Panasonic HG-C1000L Series Instruction Manual

Stable sensing is not possible.
3-point teaching (window comparator mode)
This is the method to perform 3-point teaching (P-1, P-2, P-3) and to set the
threshold range by setting threshold 1_SL in the mid-point between the 1st
time and 2nd time, and threshold 2_SL in the mid-point between the 2nd
time and 3rd time as shown in the following figure.
When performing 3-point teaching (window comparator mode), preset "Win-
dow comparator mode 3" in the sensing output setting of the PRO mode.
For the setting method, refer to section 13, "PRO mode
When performing teaching, use sensing objects (P-1, P-2, P-3) with differ-
ent distance.
After teaching, P-1, P-2 and P-3 will be automatically rearranged from the
smaller value.

Span adjustment in 'Rising differential mode' or 'Trailing differential
mode'
This mode is used to cancel the gradual changes in the measured values
and to only detect sudden changes.
To use the Rising differential mode or Trailing differential mode, preset 'Ris-
ing differential mode' oder 'Trailing differential mode' in the sensing output
setting of the PRO mode.

● The fine adjustment of the threshold can be performed in the measure-
ment display.
● The fine adjustment of the threshold can be performed even after
teaching.
