entering this mode are recorded and stored in memory. MAX or MIN or present values can be reviewed by successive presses
of the MAX/MIN button. When MIN and HOLD are displayed, the reading shown is the "lowest" since entering this mode. When
MAX and HOLD are displayed, the reading shown is the "highest" since entering this mode. When neither MAX nor MIN nor
HOLD are displayed, but the manual ranging symbol remains, the present value is displayed and recording continues.
Auto Power Off is overridden in the MAX/MIN Record mode so that recording may be extended for many hours if desired. To
use the MAX/MIN Record mode properly, first connect the test leads to the point of measurement and then wait for the reading
to stabilize. After it stabilizes, press the MAX/MIN button. If the button is pressed before the test leads are connected, the MIN
reading will be zero. Also, the meter reverts to manual range operation upon entering the MAX/MIN Record mode. if the test
leads are not yet connected, the meter will remain in the lowest range and may over-range when connected. If the variation
swing of the value is great, it may be necessary to manually step to a higher range to prevent an over-range condition on the
MAX value.
To exit the MAX/MIN Record mode, hold the MAX/MIN button down for about 2 seconds.
The MAX/MIN Record mode operates at the speed of the display update, about 2 times per second. That is, it records the MAX
or MIN reading of the display. The speed of acquisition in this mode differs (slower) from the PEAK HOLD operation.

The PEAK HOLD feature allows measurement of a peak value, for example, the starting current of a motor.
To measure peak current, clamp the meter jaws around the conductor and place the meter in a PEAK HOLD mode before
starting the current. Select AC current, meter reverts to manual ranging, then press the P PEAK button twice so the HOLD P
annunciator is displayed along with manual range indicator.
