middle or end number of 4, 5, or 6. The PT140 has a 4-20mA signal output; the PT150-
7.5M has a 0-5Vdc signal output, while PT276-5M has a 0-10Vdc signal output. NOTE: If
using 0-10V transmitter, do not connect RCal leads to terminals 14 & 17.
If you have a strain gauge transducer, load cell, or other mV/V device, see other section.
The Instrument’s default setting is strain gage input. To select another input for a
transmitter or to use another process instrument, such as humidity sensors, position
sensors, etc., press the FUNC key until nonE and GROUP show on the display. Press
the t key until 5 shows in the upper display. Press the FUNC key and the upper display
will show Str while the lower display shows PI.TYP. Press the u or t key until the upper
display changes to the correct value (0-20 for 0-20 mA linear input, 4-20 for 4-20 mA
current loop input, 0-5 for 0-5Vdc linear input, and 0-10 for 0-10Vdc linear input. Press
the FUNC key to set the value. Press the RESET key to go back to the active display.
Remember to change software configuration to correspond to the proper input.
8.3.4 Setting the Primary Input Full-Scale Value
The model number of the transducer or transmitter will designate the full-scale pressure
capability. For example, model number TPT432A-5M-6/18 indicates that the full-scale
pressure is 5,000 (5M), while the PT150-5C indicates that the full-scale pressure is 500
(5C). Since the default value in the instrument is 10,000 full scale, the input full-scale
value must be changed to 5,000 (or 500). Note that there are no units here, it can be psi,
bar, mPa, kg/cm

or any engineering unit; the magnitude is all that is important. To set
the full-scale value, press the FUNC key until nonE and GROUP show on the display.
Press the t key until 3 shows in the upper display. Press the FUNC key and the upper
display will show 10000 while the lower display shows PI.FSV. Hold the u or t key until
the upper display changes to 5000 (or whatever the full-scale value of the primary input
may be). Press the FUNC key to set the value. Check that the next display reads 0 in
the upper display and PI.LSV in the lower display; if not, set to zero with the arrow keys
and press FUNC to lock in the value. Finally, press the RESET key to go back to the
active display. Similarly, if the full-scale pressure is 350 Bar (3.5CB), set PI.FSV to 350.
8.3.5 Setting the Primary Input Low-Scale Value
For applications where a low scale value is non-zero, the Instrument can provide a low
scale value of ±25% of the full scale value.
To set the low-scale value, press the FUNC key until nonE and GROUP show on the
display. Press the t key until 3 shows in the upper display. Press the FUNC key and
the upper display will show a value while the lower display shows PI.SFV. Press the
FUNC key and the upper display will show 0 while the lower display shows PI.LFV. Hold
the u or t key until the upper display changes to whatever the low-scale value of the
primary input may be. Press the FUNC key to set the value. Finally, press the RESET
key to go back to the active display.
