9.2.2 GENERAL CALIBRATION PROCEDURE
1. Set the dip switches to calibration mode as shown above. The upper display should show
CAL
while the lower display shows
UPR
.
2. Use the ▼ or ▲ keys to show the following functions:
•Firmware revision
• Zero input counts (ZERO)
• Pressure input counts (STR)
• Reference junction counts (RJ)
• Remote set point, linear temperature input and line resistance for RTD input (RSP.RL)
•Thermocouple and RTD input (TC.RTD)
• Digital inputs status (DIG.IN)
•Maximum Power Consumption
•Minimum Power Consumption
3. The display values for analog inputs are scaled from 0 to 25,000 counts; it is also linear for RTD
input.
4. Use the ▼ or ▲ keys to select a display value from 0 to 10 and to check the linearity of output
circuit at 0%, 10%, 90% and 100%.
