4.3 Operating Timing
ES51916 incorporates a dual slope ADC with four phases: ZI, AZ, INT and DINT.
The timing of each phase are listed below.
*Voltage /Current /ohm /ADP measurement:
Phase
ZI
Time
20ms
AZ
20ms
INT
DINT
100ms
110ms
P.S. In the DC voltage and ohm measurement with auto mode, if the range is
changed, the internal clock rate will increase five times and the new measurement
cycle becomes 1/5 times of the original cycle until the range is stable.
*Continuity/diode measurement
Phase
ZI
Time
4ms
AZ
4ms
INT
DINT
20ms
22ms
*Frequency measurement
In range FR1, the measurement cycle = 0.5 sec
In range FR2~FR6, 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.
