Testing For Continuity; Testing Diodes; Capacitance Measurement - KNOVA KN 8058 Operation

Measurement Operation
• The LCD displays OL indicating open-circuit for
the tested resistor or the resistor value is higher
than the maximum range of the meter.
• When resistance measurement has been
completed, disconnect the connection between
the testing leads and the circuit under test, and
remove the testing leads away from the input
terminals of the meter.

WARNING
To avoid damages to the Meter or to the
devices under test, disconnect circuit power and
discharge all the high-voltage capacitors before

testing for continuity..

To avoid harm to yourself, do not input higher than
DC 60V or AC 30V voltages.
To test for continuity, connect the Meter as below:
1. Insert the red test lead into the Ω terminal and
the black test lead into the COM terminal.
2. Set the rotary switch to
button to select measurement mode.
3. The buzzer sounds continuously if the resistor to
be tested is <10Ω. The buzzer does not sound
if the resistor to be tested is >35Ω
Note
• Open circuit voltage is around 0.45V
• When continuity testing has been completed,
disconnect the connection between the testing
leads and the circuit under test, and remove the
testing leads away from the input terminals of
the Meter.
E. Testing Diodes (See figure 6)
WARNING
To avoid possible damage to the meter and
to the divice under test disconnect circuit power
and discharge all high-voltage capacitors before

testing diodes.

To avoid harm to yourself, do not input higher than
DC 60V or AC 30V voltages.

1. Insert the red test lead into the Ω terminal and
the black test lead into the COM terminal.
2. Set the rotary switch to
botton to select
3. For forward voltage drop readings on any
semiconductor component, place the red test
lead on the components anode and place the
black test lead on the components cathode.
The measured value shows on the display.
Note
• In a circuit, a good diode should still produce a
forward voltage drop reading of 0.5V to 0.8V;
however, the reverse voltage drop reading can
vary depending on the resistance of other
pathways between the probe tips.
• Connect the test leads to the proper terminals as
said above to avoid error display. The LCD will
display OL indicating diode being tested is open
or polarity is reversed. The unit of diode is Volt (V),
displaying the forward voltage drop readings.
• When diode testing has been completed,
disconnect the connection between the testing
leads and the circuit under test, and remove the
testing leads away from the input terminals of
the Meter.
