WirinG & confiGuration

Connect the transmitter to the control system and power supply as indicated below.

Optional: Connect the ZERO terminals to the digital output (contact closure) of the

control system.

Use the switch to select voltage (V) or current (mA) mode.

Jumper JP4: select 0-10 V or 0-5 V output span (voltage mode only).

Jumper JP5: select bidirectional or unidirectional mode.

Jumper JP7: select inches W.C. or Pascal scale

Jumper JP8: select fast or standard response time.

Align the arrow (not the slot) on the rotary switch to the desired full-scale range. LCD

models momentarily indicate the selected range.

oPeration

PX Series devices employ ceramic capacitive sensors and sophisticated temperature
compensation circuitry. The sensor achieves its best accuracy af ter an initial warm-up
period. During the rst few minutes of operation, readings at zero pressure and the
lowest pressure ranges appear erroneous. Following this initial warm-up period, PX
Series maintains its specied accuracy and stability.

LCD DISPL AY: The display momentarily indicates range “SET” when selec tion is made.
Pressure is normally indic ated on the display. Units are in inches water column (in. W.C.),
Pascals (Pa) or kilopascals (kPa) as indicated on the display. The display shows OVER
when the pressure is over range.

ZERO: Press and hold the ZERO pushbutton for 2 seconds or provide contact closure
on ‘AUX ZERO’ terminal to automatically reset the output and display to zero
pressure. To protect the unit from accidental zero, this feature is enabled only when
the detected pressure is within about 0.1 in. W.C. (25 Pa) of factory calibration.
