6. “DC/AC” Button
Used to switch between DC and AC function or between °C and °F.
When the rotary switch is in “ “, “10 “, “m ” or “μ ” position, you can press this “DC/AC” button to
switch between DC and AC function; when AC function is selected, “ ” will appear on the display as an
indication; when DC function is selected, “ ” will appear on the display as an indication.
You can press the “DC/AC” button to switch between °C and °F when the rotary switch is in “TEMP”
position. When Celsius temperature measurement is selected, “°C” will appear on the display as an
indication; and when Fahrenheit temperature measurement is selected,“°F” will appear on the display as
an indication.
