2) Install jumpers on J1, J2 and J3 as required.
a. Using the range number from 1c above, find the corresponding
range number in Chart 2.
b. Install jumpers on J1, J2 and J3 on device, as shown under the range
number in Chart 2. (Grey colour indicates that a jumper is installed.
Reference figure 3 for jumper installation.)
1) To change the measurement unit appearing on the display, install a
jumper to both pins of J5 (see Figure 3).
2) Push down the zero button and the measurement unit options (Pa,
kPa, mbar, inchWC, mmWC, psi) will cycle on the display.
3) To select a unit option to display, remove the jumper from J5
while the measurement unit is visible on the display.

Chart 2
The response time affects how fast the transmitter reacts to changes in
the system. The response time is the time the device takes to reach 63
% of the measured value. To smooth out unstable pressure fluctuations
in airflow applications, select a longer response time.
Example:
Selected response time: 8.0 seconds
Result: Output signal achieves a new value in 20 seconds (Response
time*5)
To change response time, install or remove jumper on J4.
(see Figure 3)
1) Install jumper on J4 for 8.0 second response time.
2) Remove jumper from J4 for 0.8 second response time.
STEP 6: SELECTING THE RESPONSE TIME
STEP 5: SELECTING THE MEASUREMENT RANGE
1) Determine the range number
a. Find the model in Chart 1.
b. Find the measurment unit (selected in step 4).
c. Find the required measurement range on the same line as the
measurement unit (b above) and determine the range number in the
header.
