I need to be able to measure 0 -5 v on my U3, when the existing HV channels are all full. I need the measurement to be to two decimal places. What would you recommend is teh best way to achieve this please? Thanks for your advice Mike

You can use 2 resistors to make a voltage divider:

I suggest R1=10k and R2=8.2k for 0-5V signals.

Or, the LJTick-Divider would work for you. Either the BIP10V or UNI10V would be fine:

Thank you. I rather thought those might be my options but I just wanted to be sure. I would guess that the LJTick divider would be more accurate and easier. I think I will get one and see how it works out.

Best wishes

Couldn't get any dividers as they are out of stock, so I made up one myself and all is working fine. Thank you for your guidance. Best wishes Mike
