Q68ADG - Abnormal Analog Input

[d4rkm4n 2]

Hi guys,

So I found that CH2 on Q68ADG is abnormal.

Whenever I short the termination, the digital value goes max to 4096.

Input is set to 4-20mA with normal resolution.

I tried to simulate 4mA-20mA but still same result.

Does this mean the CH2 is damaged? Equipment at site is normal and give 5mA signal.

Thanks!

It may be that the CH2 is damaged and it may also be that you need a better digital display, probably a LED display. See this https://dynamo-led-displays.ae/
