Hi
I need some help with setting up ADP1000 in Node-Red in ORP measurement mode. I have a setup where ADP1000 is connected to HUB5000 on Port 1. I have a REDOX/ORP Sensor connected to ADP1000.
I have following flow:
The parameters of VoltageInput Node are:
The parameters of Inject Node are:

The problem is that when ORP sensor is in buffer solution, it reports 310mV, which is measurable. But as soon as I put it into distilled water, the voltage starts to increase and if it becomes more than 400mV the node reports: {"code":4105,"description":"Saturation Detected."}
If I try to change the voltage range using inject node, the VoltageInput node reports: "setVoltageRange success", but it still outputs saturation message.
What is wrong here? Phidget Control Panel also shows strange logs and no voltage measurement:
The flow is below:
Code: Select all
