4.7 Continuity testing

1. Select the (
2. Connect the BLACK and RED test probe tips to the circuit or
device under test, making sure it is de-energized first. An acoustic
tone will sound if the measured value is lower than 100Ω..

4.8 Diode testing

CAUTION
Measurements must only be made with the circuit power
OFF.
1. Set the rotary selector switch to the (
2. Follow step 3 as for resistance measurements.
3. The RED lead should be connected to the anode and the BLACK
lead to the cathode. For a silicon diode, the typical forward voltage
should be about 0.6V.

4.9 Logic testing

1. Insert the BLACK and RED test leads into the COM and VΩ input
terminals respectively.
2. Set the rotary selector to the LOGIC position
3. Connect the test lead BLACK end to the reference line of the logic
bus to measure.
4. Connect the test lead RED end to the logic line to measure.
