To exit MIN MAX mode, press O N (CANCEL) or
turn the rotary switch to a different position. Also, MIN
MAX mode turns off automatically when a flashing B
(low battery condition) occurs.
Note
Minimum, maximum, and average values stored
in the MIN MAX mode are lost when the meter is
turned off.
The MIN MAX mode can be used to capture intermittent
readings, store maximum readings while you are away, or
store readings while you are operating the equipment
under test and cannot watch the meter. The average
reading is useful for smoothing out unstable inputs,
calculating power consumption, or estimating the percent
of time a circuit is active.
The MIN MAX mode is appropriate for storing signal
events that last 50 ms or longer in most measurement
functions. Signal events must be 500 ms or longer in the
following functions: continuity, conductance, capacitance,
temperature, Hz, duty cycle, and pulse width.
