R Pushbutton
The pushbutton selects different operations, depending on
the position of the rotary switch AND how long you hold it
down. See Table 3:
Press R for less than 1 second (a "momentary"
press) to perform stepping or toggling operations
(e.g., stepping through ranges or toggling between C
and F).
The meter acknowledges a momentary press by a
click.
Press R for more than 1 but less than 2 seconds
to enter the MIN MAX mode. In MIN MAX, the lowest
and highest readings are stored. (See "How to Use
MIN MAX ....")
The meter acknowledges a 1-second press by a click
and a beep. The display briefly shows, "MAX", "MIN",
and "nn".
Press R for 2 seconds or longer to toggle be-
tween the primary and alternate function of a switch
setting. (Primary functions are labeled white, secon-
dary functions yellow.)

The meter acknowledges a 2 second press by a click,
a single beep, and a double beep. The display briefly
shows "- - - -".
Pushbutton operations are summarized in Table 3.

Standby (Sleep) Mode

If the meter is ON but the rotary switch or the pushbutton
is not operated for 30 minutes, the meter enters the
standby mode and the display goes blank. This extends
battery life.
To resume operation, turn the rotary switch or press
R.
Standby is disabled in the MIN MAX mode.
