Probe Input Guard; Beeper; Hi/Lo - Tektronix DMM912 Manuel D'instructions

Probe input guard

The meter beeps continuously and displays ProbE if a
probe is inserted in a current input connector and a
measurement other than current is selected.

Beeper

A single beep indicates correct operation; two beeps
indicate a warning or error condition. Use the Setup menu
to set the beeper mode on or off. Continuity checks and
the probe insertion guard are not affected by turning the
beeper off.

HI/LO

HI/LO mode allows you to set high and low limits that
the input is compared to. A single beep indicates the
measurement is within the limits; two beeps indicate a
value outside the limits. When outside the limits, either
HI or LO is indicated in the upper display.
Use the Setup menu to set the HI and LO limits. To retain
the new values, press EXIT SETUP.
Two beeps sound (error) under these conditions:
Limits not set for the selected function or range
LO is greater than or equal to HI
