Can I have multiple math functions (Null, Min-Max, dB, dBm, Limit) turned on at the same time on the 34405A Digital Multimeter?
No, you cannot have multiple math functions (Null, Min-Max, dB, dBm, Limit) turned on at the same time on the 34405A Digital Multimeter. Only one math operation can be turned-on at a time. Selecting another math operation when one is already on will turn off the first operation and turn on the second operation instead.
