Input Reading Offset
This menu lets you set an input reading offset function to
make up for the input signal's inaccuracy at any given
point. For example, at temperatures below 400
°
F, a type J
thermocouple may be inaccurate ("offset") by several
degrees F. Use an independent thermocouple or your own
calibration equipment to find the offset for your equipment.
To correct for offset errors, change the factory default
setting to a positive or negative value for the channel you
are editing. (A positive value increases the reading and a
negative value decreases it.)
Selectable values: -300 to 300 for thermocouples with the
following exceptions when Input Units are set to
°
F
NOTE! If the input type is set to Linear, Pulse, or Skip,
you will not see this menu.
TC Offset Range
B -300 to 76
S -300 to 76
R -300 to 66
