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 measurements errors. For non-square wave signals, an additional
5 counts needs to be added.
2 The maximum measurement level is < 30 V pp.
3 The minimum measurement frequency of low frequency is set by power-on option to speed up the measurement rate.
