Processing time of main commands and Impedance measurement time

Processing time of main commands

Processing time of main commands | Impedance measurement time

The command processing time is the time until the next command is accepted.

It does not include the response time of the hardware.

The processing times indicated here are typical values.

They are not warranted.

Impedance measurement time

Processing time of main commands | Impedance measurement time

The approximate time for the impedance measurement "S" can be expressed by the following formula. Set the time interval "ΔT (time to read the measurement data after the measurement started)" for longer than the setting time of the impedance measurement "S".

    

 

(Example) When it is set for the Frequency at 0.1 Hz, the Integral average count for 4 times, and the Moving average count for 2 times.

The time for the impedance measurement takes (0.8 + 10 X 4) X 2 = 81.6 seconds.

When it is set for the time interval "ΔT" at less than 81.6 seconds, you can not read the correct measurement data because the impedance measurement is not completed. Set the time interval "ΔT" with extra allowance.
