aincal
Purpose To set or retrieve the measurement modifiers (adder multiplier) for the current analog
input range.
Query
Classic
“AINCALn a,m”
“AINCALn?”
“AINCALn=a,m”
“AINRNG”
Default “AINRNGn 0,1”
Arguments n:
a:
m:
The input channel to modify (1 through 4).
The adder modifier in the current range units (V, mV or mA).
The multiplier modifier.
Remarks These modifiers allow the user to adjust the measurement displayed. The Adder
value is normally set at 0, and the multiplier is set to 1 to display the actual measured
value. The displayed measurement is calculated as:
Disp = (Meas m) + a

ainR
Purpose To request the next available measurement of the analog inputs.
Query
Classic
“AINR”
“AINR?”
Remarks
The PPC2+ measures the analog inputs every 0.75 seconds. This command
requests the next measurement cycle results from the PPC2+. The results are
returned for all four analog inputs at once, Input #1 measurement is first, followed by
the measurement unit. Then a comma is used to separate the first measurement
from the next field. This is repeated for inputs #2, #3, and #4. If an auto-calibration
cycle is occurring, “BUSY” will be returned instead.
