Hold the key “down“during
switching on
the device until “
T.OF

Slope correction of temperature measurement in [%]
The temperature input can be adjusted with offset (
T.OF
) and scale (
T.SL
). A reasonable adjustment presumes
reliable references (e.g. ice water, controlled precision water bath, etc.).
If the inputs are adjusted (i.e. offset and scale are different from factory settings) the device will shortly
display “
T.OF
“/ “
T.SL
“ after turned on.
Default setting for offset
and scale are “
OFF
“=
0.00
, i.e. inputs are not changed.
Zero point correction:
Displayed value = measured value
–“
T.OF
”
Zero point and slope correction:
Displayed value = (measured value -
T.OF
)
• (1 +
T.SL
/ 100)
Displayed value °F = (measured value °F - 32°F -
T.OF
)
• (1 +
T.SL
/ 100)
Example:
Before starting the measurement, the values for “
T.OF
”
and “
T.SL
” are set to “
0.00
(
OFF
)” – “°
[
“ is
selected
for the parameter “
UN,T
”. For reference in a water bath, a clinical thermometer is
used.
Display value in ice water (given value offset = 0.0 °C):
Display val. offset = -0.2 °C
Display value in water bath (given value slope = 37.0 °C):
Display val. slope = 36.6 °C
Calculation:
T.OF
= display value offset - given value offset= -0.2 °C
– 0.0 °C = -0.2 °C
T.SL
= (given value slope / (display val. slope -
T.OF
) - 1) * 100
= (37.0 °C / (36.6 °C - (-0.2)) - 1) * 100
≈ 0.54 (rounded)
