5. Input current calibration
Normally, input current dose not need to be calibrated. If input
values (S value) have a displacement in auto mode after the
above adjustment, input current of 4 to 20mA DC can be
calibrated.
Press the Down or Up button
( ) in calibration mode to
select signal-zero (S-O).
Apply an input current of 4mA DC
and press and hold down the set
button ( ) for 1sec. or longer.
The LCD displays go (Go) for
confirmation. To implement
calibration, press and hold down
the set button ( ) for 1sec. or
longer again.
LCD bars (----) are displayed during
calibration.
LCD displays pass (PASS) after
calibrating the input current has
been completed, and the calibration
(CAL) mode selection screen
returns automatically.
Keep pressing the Down or Up
button ( ) in calibration mode
and select signal-finish (S-F).
Apply an input current of 20mA DC
and press and hold down the set
button ( ) for 1sec. or longer.
The LCD displays go (Go) for
confirmation. To implement
calibration, press and hold down
the set button ( ) for 1sec. or
longer again.
LCD continues to display bars (----)
during calibration.
The LCD displays pass (PASS)
after the input current has been
calibrated, and the calibration
(CAL) mode selection screen
returns automatically.
