C_TIME
Direction output
Binding
None
Type
7-element integer array
Value range
0 - 60, 0 - 24, 0 - 31 depending c, on the element
Units
Days, hours and minutes
Description
ACAL and SCAL only; times and dates to initiate calibration cycles, and the time
and date the last one occurred;
The hour of day to initiate the next calibration cycle.
The minute in the hour to initiate the next calibration cycle.
The day of the month to initiate the next calibration cycle.
The hour of day that the last calibration cycle occurred.
The minutes in the hour that the last calibration cycle occurred.
The day of the month that the last calibration cycle occurred.
The month in which the last calibration cycle occurred.
Usage
The first three elements control the starting time of the next calibration cycle
calibrations will occur at intervals after this as set by TIME-PERIOD. The last four
elements show when the last cycle actually occurred, and completed. Setting the
first three elements to zero will disable the repetitive calibration cycles.

Type
4-element floating point array
Value range

Units None
Description
AIO and ACAL only.
Voltage offset output calibration factor.
Voltage gain output calibration factor.
Current offset output calibration factor.
Current gain output calibration factor.
Usage
Sets the calibration of the output circuitry. Set the desired output units (voltage or
current), then use TESTMODE to set the operation of the software, and then
IODIAG to set the desired output current or voltage, and use this variable to make
the output match what is expected. It is often necessary to iterate between settings
of offset and gain a few times to get a perfect calibration.
