156 - Additional Information
Calibration ranges, corresponding coefficients and examples of calibration
points:
†)
sub-range 5 is presented twice since it needs to be entered separately
both for negative and positive sides.
*)
the range limits in the adjacent list are rounded and shown as they are
on MC6-T User Interface.
#)
Not all calibration laboratories necessarily use the same points. These
are for reference only.
Note: If your calibration certificate include two sets of
coefficients. One for zero current and another for 1 mA current,
enter the latter ones into MC6-T.
When selecting ITS 90 PRT (R tpw,…) as the Sensor Calculation
Formula
, the
Sensor Range
entered in the 1
st
configuration page defines
how many additional User Sensor pages is added to MC6-T. If the range
includes temperatures below zero, the total amount of configuration pages
is four:
1. First page for general settings. See Figure 145: 1st configuration
page .
2. Second page for entering the R tpw constant value.
3. Third page for selecting the deviation formula for negative
temperature subrange and entering the coefficients (a
4
and b
4
or a
5
and b
5
).
4.
Fourth page for selecting the deviation formula for
positive
temperature subrange and entering the coefficients (a
5
, a
6
, a
7
… etc.).
