In Depth Command Description: C024
Select Analog Input Scale
The RLC-1 has the ability to interpret the readings from the Analog Input Lines on several
different scales with a variety of resolutions and ranges. This command allows the user to select
which of several preprogrammed scales is attached to each of the analog input lines. Please note
that this command selects only the way the input is interpreted; see Page 14 on the Analog Input
Lines to select whether the actual input voltage is to be dealt with the 0..4V or 0..25V range.
Command C023 allows the user to assign and adjust offsets for the analog input lines. Because
the input circuits are not exactly alike, this offset adjustment may be needed to calibrate the lines.

Note: ±2 is only meant to indicate the resolution of the measurement, not its accuracy;
that is dependent on the temperature sensing device and how well the system is calibrated.

Error Messages:
If the format is not correct, the RLC-1 will send a "E" error code.
ER1 - Not Valid Analog Line
ER2 - Invalid Analog Faceplate
ER3 - Not Enough Digits
