Checking Charge on 2 unit Mini Split

I have a mini split system with an outdoor unit that has 1 zone for an 18kbtu inside unit and another zone for 2 9k units (there are 2 compressors). I want to check the charge on the system with the 2 units. Should both units be running to check the pressure?

Why do you want to do this?
You cannot diagnose an inverter drive mini with gauges.
