Installation and Operations Manual
Analog Output User Calibration
To calibrate the Analog Output, do the following:
Warning!
Obtain a hot working permit before beginning this procedure.
Output Calibration of Channel 1
1. Connect terminals A+24V and AO1+.
2. Connect a calibrated 4-20 mA Meter to terminals AO1- & AI COM.
3. If the 24VDC Output Power supply is not turned on, turn it on using the following steps:
a. Select the Basic Setup from the main Menu on the 2920.
b. Scroll to the Config Params menu.
c. Scroll to the Control parameter.
d. Set the control parameter to On.
4. Select Calibration from the main Menu on the 2920.
5. Select Analog Output.
Config Params
Pnt Ref
The reference parameter used to automatically control
the 4-20 mA output signal. Some examples are Tank
Level, Tank Temperature, Encoder Level, and so on.
Control
When the Control Parameter is set to Enable, the data
value from the PntRef is used to control the output
value of the AO channel.
Zero
The Zero, Span, and Calibration points are similar to that
in the AI point. In this case, the AO is generating a 4-20
mA signal. If you wanted to send the 4 to 20 mA as a
level in the range of 0 to 25 feet. The zero would be 0
and the Scale would be 25. When the level was at 0 ft
the AO would send 4 mA, and when the level is at 25 ft,
the AO would send 20 mA.
Span
Cal. Point #1
Calibration points form a curve which is used to correct
the output signal, #1 corresponds to 4 mA.
Cal. Point #2
Calibration points form a curve which is used to correct
the output signal, #2 corresponds to 8 mA.
Cal. Point #3
Calibration points form a curve which is used to correct
the output signal, #3 corresponds to 12 mA.
Cal. Point #4
Calibration points form a curve which is used to correct
the output signal, #4 corresponds to 16 mA.
Cal. Point #5
Calibration points form a curve which is used to correct
the output signal, #5 corresponds to 20 mA.
