This section will detail steps necessary to calibrate the CAMM. Calibration is accomplished using the four programming
push buttons detailed in Section 5.
This section can be accomplished with CAMM mounted in its operating location or at a test bench in a calibration lab.
If calibrated at a test bench, CAMM should be positioned in the same attitude as in its operating location.
6.1 – REQUIRED EQUIPMENT
1. Digital Manometer capable of reading to the nearest 0.001" w.c.
2. Digital Multimeter.
3. Absolute Pressure gauge capable of reading 0 to 40" Hg.
4. Voltage/Current generator.
5. Source of clean, dry instrument air.
6. Adjustable low pressure regulator, such as AMC "Low Pressure Air Source" or equal.
7. Vacuum pump with regulator.
8. Temperature Simulator.
9. Pressure Regulator.
6.2 – PREPARATION
1. Turn CAMM Power switch OFF (see Figure 4.1).
2. Close valves on Total and Static pressure signal lines.
3. Remove test tee caps on Total and Static pressure fittings on CAMM.
4. Remove all signal wires connected to terminals 1 through 10 (see Figure 4.3).
5. Prepare test equipment as shown in Figure 6.1.
6. Turn Power switch ON.
