MAX/MIN Button

Meter do not take records when the display reads over (+/- 4300), The negative
overrange will not happen when the function of MIN is displayed.
Press (MAX/MIN) to enter the MAX MIN AVG Recording mode (manual range
only). The RECORD annunciator turns on and the automatic power-off  feature
is disabled.

average(AVG) and present readings. (AVG) is average last ten times reading
can be displayed. Press and hold down the (MAX/MIN) for 2 seconds to exit
and erase recorded reading.
