6. Press the OUTPUT key on the Type STT terminal, then
select MONITOR OUTPUT.
7. The Type STT terminal should display 0.00% plus or
minus the tolerance for the particular transmitter listed in
Table 4-2.

8. Apply a pressure to the cell equal to the configured or
desired upper range value.
9. Since the transmitter is configured for digital operation,
the milliammeter should read below four milliamperes.
NOTE: If the four to 20-milliampere output changes with respect to
pressure, then the unit is not in the digital mode. To enter this mode,
press the CONFIGURE key on the Type STT terminal and follow the
step-by-step procedures in the Type STT Smart Transmitter Ter-
minal Instruction . Use the SEND CONFIG key to download the
new configuration to the transmitter (refer to
10. Press the OUTPUT key on the Type STT terminal and select
MONITOR OUTPUT.
11. The Type STT terminal should display 100.00% (±0.15%).
12. If the digital output is not within the limits stated in
Steps 7 and 11, calibrate the transmitter. To do so, press the
CALIBRATE key on the Type STT terminal and follow the pro-
cedures in the Type STT Smart Transmitter Terminal
Instruction.
13. Turn the - (negative) test terminal jumper screw clockwise
until tight.
By pressing the RERANGE key on the Type STT terminal, the
current (four to 20-milliampere) output can be quickly
reranged to represent a different portion of the input span.
This procedure bypasses the need to completely configure the
Type PTSP pressure transmitter. Damping, engineering units,
