allows the input value to be changed to agree with an external reference or
to compensate for sensor error. Note:

Digital Filter: Select

1

to

. In some cases the time constant of the

sensor, or noise, could cause the display to jump enough to be unreadable.
A setting of 2 is usually sufficient filtering (2 represents approximately a 1
second time constant). When the 0.1 degree resolution is selected this
should be increased to 4. If this value is set too high, controllability will
suffer.
