ES51964(6600counts)
Dual Display
6.3. Operating Timing
ES51964 incorporates a dual slope ADC with four phases: ZI, AZ, INT and DINT. The
timing of each phase is listed below. The Bar-graph ADC is 10X faster than slow ADC.

*Frequency + Duty cycle mode measurement
In range 66.00Hz~66MHz, the measurement cycle = 1.05 sec
P.S. In the frequency measurement with auto mode, if the range is changed, the internal
clock rate will increase ten times and the new measurement cycle becomes 1/10 times of
the original cycle until the range is stable.
