Notes for frequency counter specifications:
1 All frequency counters are susceptible to error when measuring low-voltage, low-frequency signals. Shielding inputs from
picking up external noise is critical for minimizing measurement errors. For non-square wave signals, an additional 5
counts need to be added.
2 The maximum measurement level is < 30 Vpp.
3 The minimum measurement frequency of low frequency is set by power-on option to speed up the measurement rate.
