AI845 1 to 5V Signal
In our site, AI845 card is configured for 1 -5V signals. In this card, when an IO channel terminal is opened, the channel does not show “underflow” immediately.
Instead of that, the channel value drops slowly.
a.It took more than 90 seconds to show “underflow” after the channel terminals are open, if voltmeter is connected across the channel terminal.
b. It took more than 10 minutes for the channel value to drop from 19 to 15 (Signal Range: 1-5V -> 0 to 40), if no voltmeter is connected across the channel terminal.
Anyone have faced similar issue?
