A long pressing (>2s) of key
MODE/MXMNPK
allows for the activation/deactivation of
continuous detection of maximum value (MAX), minimum value (MIN), positive peak (Pk+),
negative peak (Pk-) of the quantity (voltage or current) to be measured. The values are
constantly updated and are displayed cyclically every time the same key is pressed. This
function is not active in position
. Press and hold key
MODE/MXMNPK
(>2s) or use the
selector to exit the function.
