D/A Trim
NOTE:
This procedure
calibrates the value of
the analog output
current at minimum
(0%) and maximum
(100%) values.
To begin, select the D/A
Trim button on the
Calibration menu.
.
This display appears.
Select the Start D/A Trim
button. A popup message
appears.
Calibrate
4 mA
Output
Connect a voltmeter or
ammeter into the current
loop.
Then, select the
OK button
in the popup; the next
message popup appears.
Observe the meter, and
select the
OK button in the
popup message to
command the transmitter to
go to 4.0 mA output.
In the Meter Value field,
key-in the value (in
milliamps) observed on the
meter, as indicated in the
example at right.
Note: If you are using a
voltmeter, use the calculator
to convert the voltage value
to mA.
In this example, the
observed value of 1.038 V
is converted to 4.152 mA.
Select
Send; the keyed-in
value is copied to the
transmitter output
algorithm.
Again, observe the resulting
mA output on the connected
meter.
If the observed value is not
4.000 mA, select
No in the
popup message, enter the
observed current value, and
select Send. Repeat until
the observed value is 4.000
mA.
If the observed value is
4.000 mA, select
Yes. The
popup message shown at
right appears.
Select
OK to proceed to 20.0
mA calibration.
