It is possible to measure resonance point by driving speaker or compact motor directly in the use of the CF-0771 which is optional signal output function of CF-7200.
The maximum output current for the CF-0771 is 50 mA. It may cause damage on the CF-0771 if the output current exceeds this rated value.
If more than 50 mA driving current is necessary, please use the AU-3500 Isolated summing amplifier together with it. In this case, maximum output current becomes 100 mA (1 Hz to 20 kHz).
When drive the electric motor or speaker by using direct connection.
