Figure 63: Setting up option I/O analog output
3.5.5b 3Option IO (slot2): calibrating analog
output
To calibrate Option I/O Analog Output, use steps as in
section “Log-in and Primary Pages” to navigate to the
Input/Output settings page. You may use a multimeter or
DCS/SCADA to calibrate the Analog Output. Regardless of
whether multimeter or DCS/SCADA is used, the steps below
remain the same. For better readability, the steps below only
indicate multimeter and does not repeat multimeter or DCS/
SCADA.
Note: Optional I/O menu uses Slot:Channel convention for
clarity. For Example, Analog Output(S2:1) indicates Analog
Output on Slot 2, Channel 1. Optional I/O is installed in the
Slot2 of the electronics stack.
1. Connect the Analog Output as in Figure 64.
2. Turn ON the multimeter (if used) and set it to measure
Current (mA) DC. Connect test lead from positive side
(Analog Output Channel 1: I/O 1) or (Analog Output
Channel 2: I/O 3) of the optional I/O Analog Output to
the positive terminal of multimeter, and the negative
lead to the negative terminal (Analog Output Channel 1:
I/O 2) or (Analog Output Channel 2: I/O 4).
3. Highlight [Option I/O (Slot 2)] and press [ENTER].
4. Then highlight [AO-AO-AI-R-1000-3W] and press [ENTER].
Then highlight [Analog Output(S2:1)] or
[Analog Output(S2:2)] and press [ENTER].
5. Then highlight [4-20mA] and press [ENTER].
6. Scroll down and select [Calibrate] option.
7. Select [Calibrate 4mA] and check if the reading on the
multimeter reads 4.00mA ± 0.01mA. If the value on the
multimeter is not 4.00mA ± 0.01mA, input the value read
on the multimeter into the Calibrate 4mA value and
press [ENTER]. Check the multimeter again verify that the
Current reads 4.00mA within ±0.01mA.
8. Select [Calibrate 20mA] and check if the reading on
the multimeter reads 20.00mA ± 0.01mA. If the value on
the multimeter is not 20.00mA ± 0.01mA, input the value
read on the multimeter into the Calibrate 20mA value
and press [ENTER]. Check the multimeter again verify
that the Current reads 20.00mA within ±0.01mA.
9. Select [Percentage of Scale] and adjust the scale to
0.00% and press [ENTER], then verify the reading on the
multimeter is 4.00mA within ±0.01mA. Adjust the scale to
50.00% and press [ENTER], then verify the reading on the
multimeter is 12.00mA within ±0.01mA. Adjust the scale
to 100.00% and press [ENTER], then verify the reading on
the multimeter is 20.00mA within ±0.01mA.
