Diode Measurement
Test voltage drop in diodes.
WARNING! To prevent electric shock, turn
off all power and fully discharge capacitors
on the circuit under test before measuring.

Resistance Measurements

Measure circuit resistance up to 40MΩ.
WARNING! To prevent electric shock, turn
off all power and fully discharge capacitors
on the circuit under test before measuring.
Note: When measuring Ohms,
start with the lowest range if the
resistance is unknown.

Connect red probe to diode's anode
and black probe to its cathode.
5.
Read measured forward biased
voltage drop on the Display.
Note: If the leads are
reversed, 1 is displayed.

When testing is complete, turn
Rotary Switch to OFF, remove
Test Leads and store with Meter.

When testing is complete, turn
Rotary Switch to OFF, remove
Test Leads and store with Meter.
Note: Sometimes resistor value and
measured resistance differ. This is due
to the Meter's output test current going
through all possible paths between leads.
Note: For low resistance measurements,
short the test leads and record the
resistance displayed. Then connect to
the circuit and subtract the recorded
resistance from the measurement
for the most accurate results.
Note: When leads are disconnected
or measurement is out of
range, OL is displayed.
