6.1.3 Measurement time
Fast, medium, slow, custom.
Slow: 800ms.
Medium: 100ms.
Fast: 20ms for ET3502, ET3503, ET3505, ET3510; 50ms for ET3501.
Custom: 5ms to 2s for ET3502, ET3503, ET3505, ET3510; 20ms to 2s for ET3501.
The measurement time must be an integer multiple of the measurement signal cycle,
so the actual measurement time is related to the frequency of the measurement signal.
The actual measurement time is calculated with the formula:
T N
real
. t 
N is the number of the measurement signal cycles contained in the set measurement
time (N is 1 when it is actually less than 1), T is a measurement signal cycle.
