D177.131.2/0 7
5.6 Status telegrams
Telegram Description Response
SC Calibration status of the actual unit of measurement, involving all components
contributing to data acquisition, as there might be a reference or monitor
chamber.
Parameter x: 0 = any of the components involved is uncalibrated, 1 = all used
components are calibrated.
x = 0 conforms to a „uncalibrated“ message on the display SC x
Note:
An electrical measurement will have the calibration status 1, even if the radiological calibration factors stored in
MULTIDOS are marked „uncalibrated“ (= set to default), as long as the electrical calibration is marked to be
„calibrated“.
Telegram Description Response
SD Device status. iiiii is a five digit decimal number, whose bits, when converted
to binary representation, signal the following condition when the bit is set:
.0
Þ
MULTIDOS display is not accessible (command timeout)
.1 Þ MULTIDOS display is not accessible (automode timeout)
.2
Þ
electrical calibration possible
.3
Þ
Set1 of application dual channel is write protected
.4 Þ radiological unit is Roentgen
.5
Þ
reference temperature for air density correction is 22°C
.6
Þ
HV error
.7
Þ
ME 48 is connected to MULTIDOS
.0 is the least significant bit
SD iiiii
Note:
If bit .0 or .1 is set, the display is not operational. The firmware still continues to execute and to measure, but all
display operations are omitted, the display will no longer be refreshed. The measured values, available by the D
telegrams, are still correct.
Telegram Description Response
SE Reads the error number. ddddd is a five digit decimal number, whose bits,
when converted to binary representation, signal the following error condition,
if the bit is set:
.0
Þ
error at calculation of measurement multipliers
.2
Þ
error during data acquisition
.4 Þ EEPROM corrected (non critical)
.6
Þ
EEPROM error (critical)
.0 is the least significant bit
SEddddd
Note:
There will never be more than one bit set at once, since MULTIDOS checks all error sequentially. Because of
that, each error condition corresponds to a discrete value of
ddddd .
ddddd is always equal to 00000, as long as the response to the S telegram is not SERR. SE is designed to give
a more detailed information of the error type.
