Field Name Variable

Description
BuffDepth Integer Shows the processing buffer depth (# of scans that processing is lagging the
measurements). Indicates how far processing is currently behind measurement.
MaxBuffDepth Integer Gives the maximum number of buffers processing lagged measurement.
Indicative of how close the program is to skipping scans.
LastSlowScan Time Time of the last Slow Sequence Scan.
SlowProcTime Integer Processing time (μSeconds) of the last Slow Sequence scan. Processing occurs
concurrent with measurement so the sum of measure time and process time is
not the time required in the scan instruction.
MaxSlowProcTime Integer Maximum process time ( μSeconds) required, as yet, for the processing of the
measurement values from one scan of the Slow Sequence Table.
CalVolts Integer
Array
Factory calibration numbers. This array contains six values corresponding to
the six measurement integration options as shown in the following table. These
numbers are loaded during the Factory Calibration and are stored in FLASH.
# Value Voltage Range
1 5000 mV
2 1000 mV
3 500 mV
4 500 mVX
5 200 mV
6 50 mV
CalGain(#) Integer
Array
Displays the Gain calibration factor for the different voltage ranges.
CalGain(#) shows the calibration factor for the voltage ranges as depicted in
the following table. These values are updated at program compile time or
when a Calibrate or BiasComp instruction is encountered in the program, if the
program uses the measurement range.
# Value Voltage Range

6 50 mV
CalOffSet(#) Integer
Array
Displays the Offset calibration factor for the different voltage ranges.
CalOffset(#) shows the calibration factor for the voltage ranges as depicted in
the following table. These values are updated at program compile time or when
a Calibrate or BiasComp instruction is encountered in the program, if the
program uses the measurement range.
