• Re-range Transmitter
• Device Diagnostics
Highlight the HART Service menu selection and push
 (Continue). When you enter some of the
submenus, a warning tells you to remove the loop from
AUTOMATIC control. Push  (Continue).
PV Zero Trim
This function sets the digital pressure value of the
transmitter to zero.
1. Push  (Trim Zero) to trim the PV output value to
zero.
2. Push  (Done) when completed.
mA Output Trim
In the mA output trim screen, you can adjust the transmitter
output.
1. Start with the 4 mA range. Push (Fetch) to get
the current measured mA value.
2. Push  (Trim 4 mA) to send the measured value
for correction. Push  (Next Point). The Product
moves to the 20 mA range.
3. Repeat steps 1 and 2.
4. When complete, push to return to the previous
point or  (Done).
Trim to Applied Values
1. Enter the LRV pressure value necessary in the Setpoint
entry and then push  and let the pressure settle.
2. Push  (Trim LRV) to trim the lower range of
pressure applied.
3. Enter the necessary URV pressure value in the
Setpoint entry and push  and let the pressure
settle.
4. Push  (Trim URV) to trim the upper range of
pressure applied.
