1. For 100 mV and 1 V ranges, the measurable frequency is up to 1 MHz at 0.5 V input signal.
2. Maximum input for the specified accuracy = 10 x range or 1000 V

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.

1. The range is from {10 µs × frequency × 100%} ~ {[1 – (10 µs × frequency)] × 100%}. For example, a 1 kHz signal can be measured from
1% ~ 99%.
2. The positive or negative pulse width must be greater than 10 µs. The range of the pulse width is determined by the frequency of the signal.
