[1] All frequency counters are susceptible to errors. Shielding inputs from external noise pickup is critical to minimize measurement errors. For non-square wave signals,
add 5 counts.
[2] Output impedance: 3.5 kW maximum.
[3] The positive or negative pulse width must be greater than 50 µs for adjustment of the duty cycle or pulse width under different frequencies. Otherwise, the accuracy
and range will be different from the specifications defined.
[4] For signal frequencies greater than 1 kHz, an addition of 0.1% per kHz is added to the accuracy.
[5] For data logging to PC, maximum number of data points is dependent on available hard disk space.
