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 20mADC can be
calibrated.
Press the UP or DOWN button
( ) in calibration mode to
select signal-zero (S-0).
Apply an input current of 4mA DC
and hold down the set button
( ) for 1sec. or longer.
The LCD displays go (Go) for
confirmation. To implement
calibration, hold down the set
button ( ) for 1sec. or longer
again.
The LCD continues to display bars
(----) during calibration.
The LCD displays pass (PASS)
after calibrating the input current
has been completed, and the
calibration (CAL) mode selection
screen returns automatically.
Press the UP or DOWN button
( ) in calibration mode and
select signal-finish (S-F).
Apply an input current of 20mA DC
and hold down the set button
( ) for 1sec. or longer.
The LCD displays go (Go) for
confirmation. To implement
calibration, hold down the set
button ( ) for 1sec. or longer
again.
The LCD continues to display bars
(----) during calibration.
The LCD displays pass (PASS)
after the input current has been
completed, and the calibration
(CAL) mode selection screen
returns automatically.
