Table 5 Output Calibration - Loop Test
Output Calibration - Loop Test
Objective
Verify the integrity of
electrical components in
the output current loop.
Connect the MC Toolkit
as indicated, and establish
communication with the
transmitter.
For these procedures,
values of components in
the current loop are not
critical, provided that
they support reliable
communication between
the transmitter and the
MC Toolkit.
Loop Test
In the Output Calibration
box, select the
Loop Test
button; the display at
right appears.
Select the desired
constant-level Output:
0
%, 100 %, or Other (any
of
0 % - 100 %).
Select the Set button.
Select the Yes button, and
observe the output current at
0%, 100%, or Other (user-
entered) %.
Note:
If the transmitter is in
Analog mode, you can
observe the output on
an externally
connected meter or on
a Local Meter.
In DE Mode, the
output can be observed
on the Local Meter or
on the Monitor display
on the MC Toolkit.
To view the Monitor display,
navigate Back from the
LOOP TEST display and
select the MONITOR
display.
This popup appears; select
Yes to continue.
Example:
DE output (100 %), as
viewed on the MC Toolkit.
