2.2.8 CALIBRATION
The MPS49 can be calibrated in-house, if desired: calibration is performed by software
adjustment only, and the parameters are password protected for security. No mechanical
adjustments are required to calibrate the MPS49.
Using a transfer calibration standard (for example the DMA's own PAMB11H), the MPS49
can be calibrated in typically less than 40 minutes. Please refer to the MPS49 Calibration
and Adjustment Manual for more information.
Stability of the calibration is better than 80 ppm full-scale over 2 years.
2.2.9 START-UP TIME
The MPS49 goes through an automatic self-test at each power-on.
The equipment is ready for operation about 180 seconds after power-on.
NOTE
if the internal heater is installed, the start-up time could become longer, depending
on the ambient temperature.
2.2.10 CONTROL CAPABILITY WITH INTERNAL PUMPS
The control capability is optimized to allow allow up to 6,000 feet/min at 50,000 feet with the
following loads:
•
Static line: 125 cu. in. (2 liters).
•
Pitot line: 80 cu. in. (1.3 liters).
2.2.11 PROTECTION
The MPS49 comes equipped with built-in protection to safeguard the test set itself and the
instruments under test, ensuring there will be no more damaged instruments or air data test
set as so often occurred on older equipment.
The hardware is intrinsically safe:
•
control valves are normally closed when not powered;
•
manual vent valves never allow Pt < Ps.
The software also incorporates the following safety functions:
