5.3 Operating Timing
ES239 incorporates a dual slope ADC with four phases: ZI, AZ, INT and DINT. The timing of each
phase are listed below.
(1) Voltage / Diode /ADP / Manual Current (for clampmeter) measurement:
Phase
High resolution High speed
ZI
50ms
5ms
AZ
25ms
2.5ms
INT
100ms
10ms
DINT
155ms
15.5ms
(2) Current mode for multimeter/Auto Current mode for clampmeter/2-range auto voltage mode:
Phase
DC / AC
DC Lower Range
ZI
50ms
50ms
AZ
25ms
25ms
INT
100ms
1000ms
DINT
155ms
175ms
(3) Continuity / Ohm measurement:

DINT
155ms
Note: INT time = 250ms for 60.00Ω range
(4) Capacitance measurement:

6.000mF
1.32sec(max)
60.00mF

(5) Frequency / Duty cycle / VAHz measurement: Every conversion takes 1.05 second.
(6) Temperature measurement: Every conversion takes 1.25 second.
Note:
1. 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.
