CALIBRATING THE CUB4RT

the components inside the CUB4RT will slowly change with the result that the
stored calibration values no longer accurately define the input circuit. For most
applications, recalibration every 1 to 2 years should be sufficient.

procedure. The following procedures should be performed at an ambient
temperature of 15 to 35°C (59 to 95°F).

Software filtering effectively combines a fraction of the current input reading
with a fraction of the previous displayed reading to generate the new display.
