C
COEF 1.000
Calibration current, the input coefficients.
Controller displays the current value = sample
value × COEF
CUR ***.*A
Displays the current controller sampling current
values. This value is the real value can not be
set.
10、the operating authority and password
Controller provides multiple passwords and access management, according to
different levels of passwords, providing different levels of operating authority,
different levels of passwords and permissions as follows:
