Figure 5-1 Pressure Sensor Calibration Equipment
1. Assemble the pressure sensor calibration equipment as shown in
Figure 5.1, but DO NOT connect the analyzer to the calibration
equipment at this time.
2. If not already done, power ON the analyzer and display the CALI-
BRATION LIST per Section 5.2.
3. Use the ▲▼ buttons to select PRESSURE
and then press ENTER to display the CALI-
BRATE PRESSURE screen.
"Measured" is the pressure value currently
being detected by the pressure sensor, while
"Applied is a known value of pressure that
will be applied for calibration purposes.
4. With both the -ΔP and +ΔP ports open to the atmosphere, observe
that the current Measured pressure reading should be 0.00 ± 0.01
inwc. If necessary, zero the pressure sensor per Section 4.6 then
repeat steps 2 through 4.
