Balancing
Thermocouple Correction (parameter:
CAL
)
The correction value is selected in
C /
F. The displayed correction value is added to the measured temperature.
Cable Compensation for Pt 100 with 2-Wire Connection (parameter:
CAL
)
Balancing is performed manually if the sensor temperature is known:
CAL
= known sensor temperature – displayed temperature value
Correction of a Temperature Gradient (parameter:
GAin
)
If the measured temperature value is not to be displayed, but rather a value which deviates from it, the GAin parameter is set to a value other than 100%:
temperature to be displayed in
C

Scaling for Heating Current Monitoring (parameter:
A H
)
The default setting for the GTZ 4121 is 42.7 A.
If the GTZ 4121 current transformer is not used for acquiring heating current, the current value must be selected at which the utilized transformer
generates an output voltage of 10 V DC.
Ascertaining the Nominal Heating Current Value (parameter:
AMPS
)
By setting
AMPS
=
Auto
, control is interrupted for about 1 second, heating is activated and heating current is measured and saved as the nominal
value. If the value is not equal to zero, heating current monitoring is automatically activated.
