Default recording period.
The variable recording period can be configured by the user.
Note: Only 32 variables can be saved at once with a recording period of 1 second.

Some of the variables in the STD file require an explanation:

Instant Flicker and PST Flicker:
The device will record the instant Flicker and the value obtained during the recording period
( Flicker PST ). The PLT value is calculated by the Mobil applications.

Harmonics:
MYeBOX measures and records the average individual harmonic distortion up to the 50th har-
monic, and the voltage and current THD value up to the 40th harmonic. Each record corre-
sponds to a block of 10 cycles, within the recording period.

Unbalance:
The device calculates the coefficients for asymmetry and unbalance in the voltages and cur -
rents of the three-phase system.
