Chapter 3. Operation and Programming
3.3.5 Changing the Lower Output Span
To adjust the lower output span, from the
Output Menu
select
Lower
and press
Enter
. A screen similar to the following appears.
Use the left and right arrow keys to select each digit to be changed and the up and
down arrow keys to increase or decrease its value. Press
Enter
to save (or
Cancel
to keep the previous value), and return to
Output Menu
.
3.3.6 Testing the Output
The Test Menu causes the MTS6 to generate a 0- or 4-20mA output, or a 0-2V output, at the percent of scale selected.
For example, in 4-20mA operation, 0% = 4mA, 50% = 12mA, 100% = 20mA. This allows the proper function of recording
or SCADA equipment to be verified. In 0-20 operation, 0% = 0mA, 50% = 10mA, 100% = 20mA
To test system output, from the Output Menu select Test and press Enter . The MTS6 will
proceed to check the settings, and a screen similar to the following will appear.
Use the left and right arrow keys to select each digit to be changed, and the up and
down arrow keys to increase or decrease its value. Press
Enter
to save (or
Cancel
to keep the previous value), and return to the
Output Menu
.
Check your output wiring. If the reading on your SCADA or DCS is off slightly, then you
may use the
Trim
feature to trim the output zero or span.
3.3.7 Trimming the Outputs
The
Trim Menu
enables the operator to compensate for differences in measurement of the 0/4-20 mA or 0-2V outputs
by connected recorders or SCADA equipment. To trim the output:
Select
Trim
from the
Output Menu
and press
Enter
. The following screen appears.
When performing a
Trim
operation, the
MTS6
unit requires you to first reset the trim. To reset the trim output, select
