Temperature Unit
This is an overall Product setting that sets the temperature units to be shown in either
Celsius or Fahrenheit.
Notes
•
The ability to change this setting to Fahrenheit is not available in
some regions.
• Mx+B and Alarm settings of temperature channels are reset when the
temperature unit is changed.
Align Channels
The Align Channels function lets the user designate a reference channel to align other
channels to so that measured offsets between sensors can be set to zero relative to one
another and the reference channel. This is accomplished with an Mx+B offset that is
automatically applied to the selected channels to make them match the reference channel.
An application where this is commonly used is for temperature measurements. For
example, a reference probe that is fully calibrated is put into a chamber with other probes
that reads 250.52 °C. With the align function, the user sets the calibrated reference probe
channel to be the reference channel. The user then sets four probes channels to be aligned
with that reference that currently read 250.52 °C, 250.68 °C, 250.71 °C, 250.33 °C. When
the user aligns the probes, the Product calculates and applies an Mx+B offset to the
probes so that the displayed measurement value is the same as the reference probe. The
result is that all four probes now measure 250.52 °C.
