VH
20
Conductivity of calibration solution.
Note:
The unit is
µ
S/cm or mS/cm.
Value range:
0.000

α
of
calibr. solution
VH
21
Temperature coefficient of calibration solution for
calibration with automatic temperature compensation.
Note:
The
α
value of the solution is temperature-
dependent and must be determined for the
current calibration temperature.
Value range:
0.00 ... 10.00 % / K
2.10 % / K
Temperature of
calibr. solution
VH
23
Temperature calibration: Field for entry of current
calibration temperature. The temperature offset is
automatically computed from this and displayed in field
VH 19 “Temperature offset”.
Note:
• With ATC: Entry of actual temperature
• With MTC: Entry of MTC calibration temp.
Value range:
–35 ... 250 °C

Automatic
HOLD during
calibration
VH
29
Activates or deactivates the automatic HOLD function for
the current output during calibration.
Note:
Hold during calibration is always active for
resistance measurement.
Value range:
Autom. HOLD during calibration off
Autom. HOLD during calibration on
on
