Users Manual
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.
