Measurement range is 750 ohms to 16k ohms, resistances less than 750 ohms report as 750 ohms, greater than 16k ohms. Accuracy is around 5% with respect to the voltage measured accross the resistor, this translates to round 50 ohms at bottom scale and 2k ohms at top scale. | Measurement range is 750 ohms to 16k ohms, resistances less than 750 ohms report as 750 ohms, greater than 16k ohms report as 16k ohms.

Pitch Mode is set up for the internal microphone but can be accessed through the microphone jack. 2V DC bias is on, AC coupled, +20dB boost is on. The resolution is +-8Hz | Pitch Mode is set up for the internal microphone but can be accessed through the microphone jack. 2V DC bias is on, AC coupled, +20dB boost is on.
