: bandwidth about 100kHz at 3dB, Open LPF (indicator of
LPF-A will be on) to eliminate the HF disturb of the LF signal below 100 kHz
which will make the measured result more reliable.

: It is used to select the measured channel. CHA can be used to
measure 1Hz ～ 100MHz signal frequency. CHB can be used to measure
100MHz～2.7GHz signal frequency.
100MHz～2.7GHz signal frequency.
2.5 For CHA,
a. When frequency is <100 kHz, please turn on the low pass filter (LPF-A).
b. When the amplitude of frequency is >5V, please use external attenuators, such
as oscilloscope-probes.

: It should choose a suitable strobe time if a suitable
resolution is needed. Once the period of the measured signal is more than strobe
time, the measurement time is regarded as a period time of the measured signal.

: Press it down, the Hold indicator will be on. Then the FC will
stop measurement. The display window will always keep the last measured data
even the signal frequency is changed or test dot is broken. Press Hold again, its
indicator will be off. Then FC re-starts to measure and the display window will
record new frequency measurement data.
