To Apply Mx+B Scaling to Measurements
The scaling function allows you to apply a gain and offset to all readings on a
specified multiplexer channel during a scan. In addition to setting the gain (“M”)
and offset (“B”) values, you can also specify a custom measurement label for your
scaled readings (RPM, PSI, etc.).
1Configure the channel.
You must configure the channel (function, transducer type, etc.) before
applying any scaling values. If you change the measurement configuration,
scaling is turned off on that channel and the gain and offset values are reset
(M=1 and B=0).
2 Set the gain and offset values.
The scaling values are stored in non-volatile memory for the specified
channels. A Factory Reset turns off scaling and clears the scaling values on all
channels. An Instrument Preset or Card Reset does not clear the scaling values
and does not turn off scaling.
3 Select the custom label.
You can specify an optional three-character label for your scaled readings
(RPM, PSI, etc.). The default label is the standard engineering unit for the
selected function (VDC, OHM, etc.).
4 Scaling is now applied to the measurements.
