7.3.10 Resistors
Resistors are passive transducers. For these transducers you will need the
ML801B amplifier module with AP835, which will provide you with a coarse
measuring range (0...500 Ω.
The settings are explained with the following example:
Resistance value 400 ΩDisplay full scale 400.00 Ω
7.3.10.1 Direct entry of transducer characteristics
1. Use
or a direct entry to choose the desired channel (for example 3.2
).
2. Use
to switch to Setup mode.
3. Press the
function key.
4. In the pull-up menu select Transducer and confirm with
.
5. Use
to select 500ohms (this is the input range of the amplifier) and
confirm with
.
6. In the Connector selection field choose the desired connection type.

7. Use to switch to the Unit selection field and press . Select
ohms as the unit and confirm with
.
8. In both the Zero point edit fields enter the value 0.
9. In the left edit field Nominal (rated) value enter the value 400.
10. Use
