[1] For 100 mV and 1 V ranges, the measurable frequency is up to 1 MHz at 0.5 V signal . Minimum input frequency is 1 Hz.
NOTE
All frequency counters are susceptible to errors when measuring low-voltage,
low-frequency signals. Shielding inputs from external noise pickup is critical for
minimizing measurement errors.
