2.6 Diode Check
Never apply voltage to the test leads. Doing
so may damage the instrument and result in
personal injury. To avoid electrical accidents,
remove power from the circuit before mea-
suring.
1.
Set the function switch.
2.
Connect the test leads to
the test terminals.
3.
Connect the test leads to
the object being tested.
4.
Read the value displayed.
With a normal diode, the
sequential order voltage (0.3 to
0.8 V) is displayed.
When the display value less
than 0.050 V, buzzer sounds.
When the display value drops to
the range of 0.3 to 0.8 V, a sin-
gle buzzer sounds to indicate
that a diode was detected.
However, in relative value dis-
play mode, this conforms with
the internally measured value,
not the display value.
