ES51982
3 1/2 CAP AUTO DMM
5.4 Operating Timing
ES51982 incorporates a dual slope ADC with four phases: ZI, AZ, INT and DINT.
The timing of each phase is listed below.
*Voltage /ohm/ADP measurement:

Ps. In the voltage and ohm 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.

*.Frequency measurement
one measurement cycle = 1.05 sec
ps. 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.
