Wait for the pressure to stabilize and press the "Get" key to directly acquire the value, or manually
enter the trim values.
Note: Some transmitters may not allow selectable trim values, and automatically use the upper and
lower range limits as trim values (the lower range limit corresponds to the lower-point trim value, and
the upper range limit corresponds to the high-point trim value). In this case, you can input any value.
3) Execute the adjustment (Trim) command. After completed successfully, the PV value will change
with the executed trim point value.
Upper trim
The operation procedure of upper trim is the same as that of lower trim.
Factory reset
Select "Factory Reset", then a prompt will ask "Are you sure to restore factory settings of the
sensor?" Press the key or click on the screen to execute the factory reset command. After
completed successfully, the upper and lower trim values will restore factory settings.
