Description
PRD
$PRD
$a,b
Query pressure value for a channel
a= gauge status
0 -> OK
1-> Ur
2 -> Or
3 -> Err 03 or Err 04
4 -> not used
5 -> No Gauge
6 -> Id Err
7 -> Err Hi or Err Lo or Err 06 or Err 07
b = measured pressure value
for gauges AP, ACC, AHC: x.xxE ± xx
for gauge AD: ± x.xxxxE ± xx
no gauge: 0.00E+00
SP1
$SP1,?
$a,b
Adjust set point ‘SP1’
a = set point low threshold SP1L
b = set point high threshold SP1H
x.xxE ± xx
SP1H >= SP1L
$SP1,a,bc
$OK
SP2
$SP2,?
$b,c
Adjust set point ‘SP2’
a = set point low threshold SP2L
B = set point high threshold SP2H
x.xxE ± xx
SP2H >= SP2L
$SP2,a,b
$OK
SPS
$SPS
$a,b
Query set points status
a = status of set point SP1
c = status of set point SP2
0 -> OFF
1 -> ON
TAD
$TAD
$a,b
Test Analogique/Digital converters
a = value of analogue signal delivered by the gauge
± xx.xxxV
-00.000V if no gauge is connected
b = value of the gauge identifi cation resistance
xx.xE+3 ohms
00.0E+0 ohms if no gauge is connected
TDI
$TDI,?
$a
Test display
a= screen test status
0 -> OFF
1 -> ON
$TDI,a
$OK
