6.1.2.4 Limits for Pressure Alarms Commands
PRESS_LIM_MIN & PRESS_LIM_MAX – These commands set the limits for pressure alarms. If the pressure exceeds the
PRESS_LIM_MAX, an error will be generated and placed in the error queue. Similarly, if the pressure drops below the PRESS_
LIM_MIN, an error will be generated and placed in the error queue.
6.1.2.5 Setting Pressure Units
UNIT_INDEX - This command sets the output units per the following table:
Unit Index Units Unit Index Units
1 psi 21 Torr
2 inHg 0C 22 kPa
3 inHg 60F 23 Pa
4 inH2O 4C 24 dy/cm2
5 inH2O 20C 25 g/cm2
6 inH2O 60F 26 kg/cm2
7 ftH2O 4C 27 MSW 0C
8 ftH2O 20C 28 osi
9 ftH2O 60F 29 psf
10 mTorr 30 tsf
11 inSW 0C 31 Not Used
12 ftSW 0C 32 uHg 0C
13 atm 33 tsi
14 bar 34 mHg 0C
15 mbar 35 hPa
16 mmH2O 4C 36 Mpa
17 cmH2O 4C 37 mmH2O 20C
18 MH2O 4C 38 cmH2O 20C
19 mmHg 0C 39 mH2O 20C
20 cmHg 0C 99 CUST_UNIT
Table 6.1.2.5 - Available Unit Codes and Units
6.1.2.6 Customer Units
The CUST_UNIT multiplier in conjunction with UNIT_INDEX 99 allows the user to set their own units. The CUST_UNIT is a
multiplier times psi to achieve the customer’s unit value.
6.1.2.7 Calibration Adjustments
SPAN & ZERO - These are calibration multipliers and offset respectively. The zero is an offset applied to all output pressure
values. The span is a multiplier times all pressure output values.
6.1.2.8 Temperature Limits and alarms
TEMP_LIM_MIN & TEMP_LIM_MAX – These set the temperature limits that trip alarms just like the PRESS_LIM_MIN and MAX.
6.1.2.9 Sea level and Altitude Units Settings
SEA_LEVEL & ALT_UNIT – These commands set the altitude units in meters or feet and allow the user to set a sea level
adjustment in altitude units. This is only applicable for absolute pressure transducers with a maximum range of <= 30 psia.
