Wrong Input Warning Feature
If the display shows
the meter is set up correctly and test the
meter's fuses as described under "Auto Fuse
Detection" in chapter 6. If the rotary switch
is not correctly set to one of the current
measuring positions, the beeper warns you
by making a chirping sound. This warning
is intended to stop you from attempting to
measure other values when the leads are
plugged into a current terminal.
Placing the probes in parallel with a powered
when a lead is plugged into a current terminal
can damage the circuit you are testing and
blow the meter's fuses because the resistance
through the meter's current terminals is so
low that the meter acts like a short circuit.

select manual-ranging and the meter will
remain in the range it was in when the LCD
annunciator turns off.

every minute. To turn on the meter, press
any button or move the rotary switch to any
position.
The second step is to automatically turn the
meter completely off after approximately
15 minutes from the time when the meter
entered the power saving mode. To turn on
