This read/write register is use to set usefile group units. The register numbers may range from “0” to
MAX_GROUPS-1 (currently “63” for a usefile). The register number is actually a use file group
number. Data values are immediately used unlike the tube image register command app.14.group
number which requires the app.6.11=1 command to make them take effect.
This means the data in the “data base” may contain mixed values.
This command is to be used
for test purposes only.
The command app24.group number will return:
App.24.group
number=AA,BBCC,DDDD
Where: AA = group number in decimal
BB = conversion group number in decimal
CC = unit number in decimal
DDDD = the flag field in ascii-hex
On write the command must be entered as AA,BB,CC,DDDD exactly. The comma separator field is
important as well a each digit. The allowed ranges for each field is determined by the entries in the
Unit_Tab.dat file.
Tube PI Calibration Byte Registers:
ARRAY.REGISTER DESCRIPTION USAGE GROUP NAME
31.0 Meter Factor Type Read/Write, see note 1) None
30.1 Meter Factor Units Read Only, see note 2) None
30.2 Number of cal Points Read/Write, see note 3) None
30.3 Calibrate abort Read/write, see note 4) None
30.4 Complete Calibrate Read/write, see note 5) None
30.5 Multipoint Calibrate Enable Read/Write, see note 6) None
1.
If 0 then the meter factor type is volume/pulse, if 1 then the meter factor type is pulse/volume. An
event (356) is logged whenever this field is changed.
2.
This field is not currently used and is reserved for future use.
3.
This field selects the number of cal points to be used. A maximum of eleven may be currently
selected. This field only takes effect when register app.30.4 (Complete Calibration) is sent. All
points above the selected point are zeroed out. An event (199) is logged when a calibration is
completed and the number of points changes.
4.
Sending this command with a value of “1” aborts any calibration in progress. It always returns “0”
on read.
5.
This command when sent with a value of “1” completes a calibration in progress. An event (198)
is logged when this command is sent. Upon reception this command, the entered values for
each point are compared against the old values and events are generated if old and new values
are not the same.
6.
This command enables the multipoint calibration feature. An event (358) is generated anytime
this field is changed.
