6. Commissioning, operation
Default setting
'
off
' = 0.0°, i.e. no correction is made. If a value other than
'
off
'
is set, this is indicated by
the offset arrow in the display during operation.
Standard characteristic curve (
Lin
E
.
751
) and user characteristic curve (
Lin
USEr
) have
separate correction settings.
6.3.5 Slope correction (
SCaL
)
The slope correction, together with the zero point correction, is mainly used for the
adjustment of probe deviations.
The slope of the measurement can be influenced by this factor (factor is in %):
Displayed value [°C] = measured value [°C] * (1+Scal/100)
or
Displayed value [°F] = (measured value [°F] - 32 °F) * (1+Scal/100) + 32 °F
Default setting
'
off
'
= 0.000, i.e. no correction is made. If a value other than
'
off
'
is set, this is indicated
by the Corr arrow in the display during operation.
Standard characteristic curve (
Lin
E
.
751
) and user characteristic curve (
Lin
USEr
) have
separate correction settings.
6.3.6 Power-off delay (
P
.
oFF
)
If no button is pressed and no serial communication occurs during the power-off delay,
the instrument will automatically switch itself off. The power-off delay can be set between
1 and 120 min. If
“
P
.
oFF
=
oFF
”
then the power-off function is deactivated.
6.3.7 Instrument output (
Ovt
)
The output can be used as a USB or RS-232 interface or as an analogue output (0 ... 1 V).
If the output is not needed, we recommend switching it off, as this reduces the current
consumption of the instrument.
6.3.8 Interface address (
adr
.)
With a galvanically isolated interface converter (accessories on request), the instrument
can be connected directly to a USB or RS-232 interface of a PC. It can connect up to 5
measuring instruments simultaneously. This requires that all instruments have a different
base address (the base addresses must be configured accordingly).
Setting the base address of the instrument for interface communication.
The assignment of the base address can be between 01, and 11 ... 91.
