When adapter Option 70 is used, set resistance value is connected to the adapter output terminals permanently.
Status of button ON/OFF doesn’t influence resistance connecting or disconnecting.
Option 80 application
The adapter is designed for mVDC and thermocouple temperature sensors measurement. Appropriate mode can
be displayed by pushing METER button and selected from list of functions. When Option 80 adapter is
connected to auxiliary connector only mVDC function with total range from 0 to 2 000 mV or temperature
measurement is available. When connected external thermocouple to Option 80, temperature of the sensor is
directly displayed. Type of thermocouple can be set in METER setup.
Table below shows measurement capability of different cable adapters connected to the auxiliary connector.
Tab.20 overview of cable adapters
Note: Option 140-70 is applicable only for four-wire simulation of resistance
Option 140-41 belongs to M-140 model accessory however measuring section of the option (field
INPUT) can be applied for M-142 model as well.
Option 90 application
Option 90 is Pt 1000 external temperature sensor suitable for automatic compensation of cold junction when
simulating TC temperature sensors.
