Title: Help, can I use another oxygen battery instead?
Post by: daisizhou on May 28, 2022, 02:44:06 am

One of my test instruments originally used psr-11-75-ke oxygen battery, because psr-11-75-ke is hard to buy, I plan to replace it with ordinary oom202 oxygen battery.
I inquired about their 2 kinds of oxygen batteries, the output voltage is different, I don't know if they can be used instead?
If it can't be used directly instead, can a voltage conversion circuit board be added to change their output voltage, and then connected to use?I mean add a small circuit board, adjust the new battery to the same linear range as the original battery and use it again.
If you know please help me, thanks

Can I use oom202 instead of psr-11-75-ke?
Their output voltages are somewhat different
