3.3.4 Analog Outputs
The
Analog Outputs
screen allows you to calibrate all the available analog outputs, such as a
valve or pump. If you select a programmable output, its function is displayed. You can also view
feedback (if available). If reliable feedback or external instrumentation indicates the reading is
inaccurate, you can adjust its reading via the
Offset
parameter. This process can be repeated
for all available analog outputs.
1. Go to:
Main Menu
→
Calibration
→
Input/Output
→
Analog Outputs
.
Figure 3.3.4: Input/Output: Analog Outputs Screen
2. Press the
Analog Name
field and choose the analog output you want to view. The chosen
output is displayed along with its current reading.

3. If you chose
Spare Analog Out 1
or
2
in step 2, the
Function
parameter provides a read-
only display of the function the output has been assigned, either
Valve
or
Other
.
4. The
Board Reference
shows I/O Board pins to which the output selected in Step 2 is
connected or
shows “On Harness”. For more information, see the I/O board diagram in
Section 2.11 of the
Benchmark Platinum-Edge Installation Manual
(OMM-0136, GF-210).
5. Set the
Level
parameter to the reading from a reliable external instrument. For example,
set the Level to 5 V or 10 mA and observe that it matches the external instrumentation or
feedback, if available. If not, enter an appropriate value in the
Offset
parameter.
(Range: 0.00 to 10.00V
or
0.00 to 20.00 mA)
6. If necessary, you can adjust the
Offset
to match a reliable reading or instrument by
entering a value in this parameter. (Range: -1.0 to +1.0
or
-2.0 to +2.0 mA, default = 0.0)
