Continuity Measurements - Wetekom 81 83 50 Instruction Manual

Notes
 If the display still shows "i" even when the test leads have been
reversed, the semiconductor is interrupted/defective.
 If the display shows a reading around zero in both connection
directions (when the leads have been reversed), the semicon-
ductor has a short circuit; it is defective.
 The polarity of a diode can be obtained as follows: When the
diode has been connected to the meter and the display shows
a voltage reading, the red test lead is connected to the anode
of the diode.

10. Continuity Measurements

The continuity test allows the testing of circuits, wires, compo-
nents etc. to electrical continuity (i.e., resistance values below
approx. 50 Ω).
1. Connect the black test lead to the COM jack (5) and the red
test lead to the VΩmA
2. Set the rotary function/range switch (2) to the
3. Connect the test leads to the circuit to be measured.
4. If the circuit resistance is lower than approx. 50 Ω, the built-in
buzzer will sound and the LCD displays the resistance value of
the circuit under test.
Note:
 Before performing in-circuit continuity tests, make sure that the
circuit under test has all power removed and all capacitors are
fully discharged.
