About t4 measurement time
When averaging is enabled, the running average is obtained with internal triggering, so
measurement time t4 does not change. The measurement time for external triggering is as
follows:
With SLOW sampling
Ω
V (t4 - 57.8) X n + 57.8 ms (50 Hz)
(t4 - 51.2) X n + 51.2 ms (60 Hz)
Ω
or V (t4 - 56.4) X n + 56.4 ms (50 Hz)
(t4 - 49.8) X n + 49.8 ms (60 Hz)
With other than SLOW sampling
Ω
V (t4 - 2.8) X n + 2.8 ms
Ω
or V (t4 - 1.4) X n + 1.4 ms
(n represents the number of values averaged)

About t5 calculation time
In the following cases, add the indicated times to calculation time t5:
When the Statistical Calculation function is enabled 0.3 ms
When the reference value/tolerance method of
comparator decision is selected 0.15 ms
