Kind of compensation
of sensor
working conditions changes:
- In case of a resistance thermometer
and resistance measurement, it
concerns the compensation of
the resistance changes of the
conductor linking the sensor with
the meter,
- In case of a thermocouple it concerns
the compensation of reference
auto
- automatic compensation
(in case of resistance thermometers and
resistance measurement it requires a
3-wire line.)
0.0...60.0
C
- value of the reference
temperature for thermocouples.
0.0...40.0
- resistance of two conduc-
tors for resistance thermometers and
resistance measurement.
The writing of a value beyond the interval
of manual compensation (e.g. value 70.0)
will cause the
automatic compensa-
tion
switching on.

Auto
- automatic choice of the
decimal point
Setting of the decimal point
. The
setting operates both when the
individual characteristic is switched
off and on. The introduction of the
decimal point making impossible
the display of four characters on the
display will cause the display of the
lower or upper exceeding.
0.0...999.9 s
The writing of
0
causes the switching of
the measurement off and the stoppage
of the meter operation. In this state, the
meter displays the hour. The bargraph
is blank.
Averaging time of the
measurement.
0n
- characteristic switched on,
0ff
- characteristic switched off.
The switching off or on of the indi-
vidual linear user’s characteristic.

Parameters of the display
individual characteristic
.
On the base of given by the user
coordinates of two points the meter
determines (from the system of
equations)
a
and
b
coefficients of
the individual characteristic.
Where:
I_H1 i I_H2 - measured value
d_Y1 i d_Y2
- expec-
ted value on
the display.
