Note:
To ensure measurement accuracy, the operating temperature should be within
18°C~28°C and the fluctuation range should be within ±1°C. When the temperature
is <18°C or >28°C, add temperature coefficient error 0.1 x (specified accuracy)/°C.

6) Hz/INRUSH Button
Short press: enter/exit the frequency measurement mode.
Only valid for ACV, LPF ACV, LoZ V~, ACA and measurement by flexible current
probe.
Long press: user has the option to select proper range with RANGE button first,
or simply long press this button to enter the inrush current measurement mode
(measurement time~100ms). Long press this button again to exit the inrush
current measurement mode.
Inrush current can also be measured with flexible current probe (UT206B/UT208B).
7) Hz Button (UT205E only)
Short press: enter/exit the frequency measurement mode.
8) FLIGHT Button
Short press: turn on/off the flashlight.
