To trim the zero value, select
Trim Zero
and press
Enter
. A screen similar to the
following appears.
This will cause the
MTS6
to output 4.000 mA or 0.4 V on the output being trimmed. The
output value should then be read using the connected recorder, SCADA equipment, or
DVM. Enter the value read from the connected equipment as the
Zero Trim
value, as follows:
Note: Since you cannot trim 0 mA or 0 V for negative offsets, trim for the lower end of the scale is at the 4 mA or
0.4 V output level.
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).
The Output Trim menu returns with Trim Span highlighted. To change the span value,

Enter the value read from the connected equipment as the
Span Trim
value.
Use the left and right arrow keys to select each digit to be changed, and the up and

The operator enters “3.977” as the
Zero Trim
value.
Trim Span
is selected. The SCADA input reports 19.985 mA.
The operator enters “19.985” as the
Span Trim
value.
MTS6
will adjust the output accordingly to true the output as read by the customer recorder, SCADA or DVM.
Using the
Test Menu
, the operator verifies that a test value of 0% now reads 4.000 mA at the SCADA equipment, and a
test value of 100% now reads 20.000 mA.
