Pt100 Input Calibration; Analog Output Calibration - ABB SpiritIT Flow-X Instruction Manual

S P I R I T
2 Select the analog input (1-6) to be calibrated.
The calibration display shows the required reference value for
the 1st calibration point.
3 Disconnect the transmitter signal and connect the loop
calibrator
4 The calibration display shows the raw input value as it is read
directly from the loop calibrator and the corrected input value
based on the previous calibration.
5 Adjust the loop calibrator such that it outputs the required
reference value
6 Wait for the signal to stabilize and issue the 'Recalibrate this
point'.
Note: recalibration is optional at every calibration point. If the
corrected signal is close enough to the reference value you
may decide to skip re-calibration of the calibration point.
7 Check that the corrected value corresponds with the
reference value and issue the 'Go to next calibration point'
command on the display.
8 Repeat steps 4 through 7 for the remaining calibration points
9 Disconnect the current loop calibrator and reconnect the
transmitter.
10 Set the "Selected analog input" to 'None' or alternatively
select the next analog input to be calibrated. The live input
signal will now be used again.

PT100 input calibration

The procedure to calibrate a PT100 input is based on a decade
box that is suitable for PT100 calibration
During calibration the process input (temperature) that
uses the PT100 input will follow the calibration value. So,
before putting an input into calibration, please be sure that one
of the following conditions is met:
 There's no flow
 The run has been set to maintenance mode
 The process value has been set to override mode
 The input has been frozen using the 'Freeze all analog and
PT100 inputs' command
1 Go to the PT100 input calibration display.
Display → IO, <Module x>, Calibration, PT100 inputs
Display → Calibration, Module <x>, PT100 inputs
With x the applicable module number, i.e. the flow module to
which the signal is physically connected.
2 Select the channel number (1-2) of the PT100 input to be
calibrated.
The calibration display shows the required reference value for
the 1st calibration.
3 Disconnect the PT100 element and connect decade box.

4 Adjust the decade box such that it outputs the required
reference value as indicated on the calibration display)
5 The calibration display shows the raw input value and the
corrected input value based on the previous calibration.
6 Wait for the signal to stabilize and issue the 'Recalibrate this
point'.
Note: recalibration is optional at every calibration point. If the
corrected signal is close enough to the reference value you
may decide to skip re-calibration of the calibration point.
7 Check that the corrected value corresponds with the
reference value and issue the 'Go to next calibration point'
command on the display.
8 Repeat steps 4 through 6 for the remaining calibration points
9 Disconnect the decade box and reconnect the PT100 element.
10 Set the 'Selected PT100 input' to 'None' or alternatively select
the next PT100 input to be calibrated. The live input signal will
now be used again.

Analog output calibration

The procedure to calibrate an analog output is based on a 4-20
mA meter.
1 Connect the mA meter in series with the load.
2 Go to the analog output calibration
display.
Display → IO, <Module x>, Calibration, Analog
outputs
Display → Calibration, Module <x>, Analog outputs
With x the applicable module number, i.e. the flow module to
which the signal is physically connected.
3 Select the channel number (1-4) of the analog output to be
calibrated. This disables the setpoint that is controlled by the
application and adjusts the analog output to the 1st
calibration point.
4 If the actual output as measured by a reference meter is not
correct, you can increase or decrease it by using the 'Increase
output' and 'Decrease output' buttons until the indication on
the mA meter matches the reference value.
5 Issue the 'Recalibrate this point' command.
Note: recalibration is optional at every calibration point. If the
output signal is close enough to the reference value you may
decide to skip re-calibration of the calibration point.
6 Check on the mA meter that the output signal corresponds to
the reference value and issue the 'Go to next calibration point'
command on the display.
7 Repeat steps 4 through 6 for the remaining calibration points
8 Set the 'Selected analog output' to 'None' or alternatively
select the next analog output to be calibrated. The analog
output will now be controlled by the application software
again.
9 Disconnect the mA meter.
