Instructions of button operation:
Short press: Press button for <2s
Long press: Press button for ≥2S
Button Description
1) Short press: Select testing functions including ACV/Hz, ACA/Hz,
AC/DCmV, continuity/resistance, diode/capacitance, ACA/HZ/DCA
(current probe measurement), NCVLO/HI.
SEL/LPF
2) Long press in ACV/Hz position to enter or exit LPF function cyclically.
3) Note: The SEL button is disabled in HOLD, MAX/MIN/AVG modes.
1). Short press this button once to enter manual range mode ("AUTO" is
not displayed on the LCD) and show current range, short press again
to select range. Long press to exit manual range and enter auto range.
Default setting will be recovered when switching position or restarting
the multimeter.
RANGE
2) Under frequency measurement mode, short press this button to select
the range of ACV/ACA (equivalent to the RANGE function corresponding
to ACV/ACA).
3) RANGE button is disabled in HOLD, MAX/MIN and REL modes.
1) Short press this button to enter "MAX/MIN" statistics mode, refresh
data continuously and view "MAX→MIN→AVG→Current measurement
value→MAX...". Long press to exit statistics mode and return to normal
working mode. (For ACV, DCV, Ω, CAP, continuity and current probe only)
2) In HOLD mode, MAX/MIN button is disabled.
3) Press REL button and then short press MAX/MIN button to calculate
the MAX/MIN value subtracted by least significant digit.
4) In LPF mode, press MAX/MIN button to calculate the MAX/MIN value.
MAX/MIN
5) When the multimeter enters statistics mode, it exits auto range and
enters current range, the symbol "Manual" flashes four times at a
frequency of 2Hz, and the auto-off function is disabled. To restore auto
range and auto-off function, please exit MAX/MIN mode (If the auto-off
function is disabled manually, the multimeter will keep this function in
disabled sate).
6) In statistics mode, short press HOLD to stop refreshing data, then view
MAX/MIN value by pressing MAX/MIN button. Short press HOLD again
to exit the HOLD mode and then refresh data.
7) MAX/MIN button is disabled in Auto-V LoZ mode.

1) Short press this button to enter or exit data hold mode. In HOLD
HOLD/ mode, they symbol " " is displayed on the LCD.
Backlight 2) Long press to turn on/off the backlight. The backlight is turned off
automatically in 5 minutes by default.
1) Short press this button to enter or exit REL mode. The LCD shows the
symbol "△" in REL mode. (For ACV, DCV, Ω, CAP, continuity, diode
and current probe only)
2) When the multimeter enters REL mode, it exits auto range and enters
current range, and the symbol "Manual" flashes four times at a
REL/BT
frequency of 2Hz
3) Under REL mode, the actual measureable scope at current range is
not changed.
4) REL button is disabled in HOLD and MAX/MIN modes.
5) REL button is disabled in Auto-V LoZ mode.
