TReX User Manual v2.14 Firmware
ADC CAL Sub-Menu
When the analog inputs are being read, scaling can be applied that allows the user to specify an
INPUT from 0-1023 over a useful range from MIN to MAX. For example, if MIN is 200 and
MAX is 400, then any analog INPUT below 200 will be SCALED to 0. Any INPUT above
400 will be SCALED to 1023. An INPUT of 300 will return a SCALED value of 512.
This is useful if a small voltage range is of interest, such as 1-5V instead of 0-10V. See
following calibration procedure for full example.
1-2
Access to calibration items for ADC 1 and ADC 2.
MIN
This is the minimum used INPUT ADC value. If no scaling is to be applied set to 0.
MAX
This is the maximum used INPUT ADC value. If no scaling is to be applied set to 1023.
SCALED
This is a read only field that displays a value from 0-1023.
INPUT
This is a read only field that displays the raw analog input value from 0-1023. The INPUT is
not scaled.
