Output Trimming
The output of the THZ
3
/TDZ
3
is accurately calibrated prior to delivery to our customers.
However, you may wish to trim the instrument’s analog output to match what you are reading
on your monitoring or control system. By example: if the THZ
3
is putting out 12.0mA and your
DCS is reading 11.85mA you can trim the output of the THZ
3
so that the two readings will match.
Note: trimming of the analog output will not affect the HART digital data.
To perform output trimming set up your THZ
3
/TDZ
3
as shown in Figure 2.11.
