Resistance measurement

I am trying to measure resistance between two points, in my case a "switch", in order to trigger once a specific resistance level is met across the switch. With only two wires from my switch, I am having trouble wiring this as an analog input. Initially, I thought simply wiring my switch in series between IN- and IN+, or between IN+ and EXC+, but neither seems to work. Hardware is a 43V, and sensor/switch is an OEM customer part, with target resistance levels in the rage of 1000-4500 ohms. Any guidance or suggestions?

Edit: we are currently doing this manually with a typical digital multimeter, so I am basically trying to replicate the ability of the multimeter's resistance measurement mode.

Hi,

DEWE-43 doesn't support resistance measurement directly, but you can use DSI RTD adapter.

Hi,

I have same issue with Iolite, 6xSTG... It seems Iolite stg supports resistance measurement, however, i can't figure out the connection diagram on the channel setup.

Dear Ersin,

the dotted lines are optional connections that you can make and the bold ones are necessary. On the picture below is an example of how to connect a resistor to the STG amplifier:

Below you can see the connection diagram explained:

I hope this helps.

Best Regards,
