Resistance or Diode or Continuity or Capacitance Measurements
WARNING:
To avoid electric shock, disconnect power to the unit under test and discharge all
capacitors before taking any resistance or capacitance measurements.
1.
Insert the black test lead banana plug into the negative
COM
jack and the red test lead
banana plug into the positive
Ω
•))) CAP
jack.
2.
Turn the rotary switch to the
Ω
•))) CAP
position.
3
Press the
MODE
button to select
Ω
or
or
•)))
or
CAP
4. Connect the test probes to the two ends of the Resistance, Diode, Continuity and
capacitance or
circuit to be measured.
5. Read the measured value from the LCD display
6. When on the continuity range, a beeping sound shall be heard if the resistance is lower
than 150
Ω
7. When measuring the forward voltage across diode a normal diode will indicate 0.4V or
0.7V and the reverse voltage will indicate “OL” (same as on open condition). For a short-
circuited diode, a value 0 mV will be display.
8. When checking in-circuit capacitance, be sure that the circuit has all power removed and
all capacitors are fully discharged. The range control mode in capacitance measurement is
auto- ranging.
Frequency or Duty Cycle Measurements
1.
Insert the black test lead banana plug into the negative
COM
jack and the red test lead
banana plug into the positive
HZ
jack.
2.
Turn the rotary switch to the
Hz %duty
position.
3.
Press the
Hz/%
button to select “
Hz
” or “
%
”.
Touch the test probes to the circuit or under test and read the frequency or duty cycle on
the display.
Temperature Measurements
1.
Insert the type K thermocouple probe black test lead banana plug into the negative
COM
jack and the red test lead banana plug into the positive
+
jack.
2.
Turn the rotary switch to the select
o
C
or
o
F
.
3.
Read the temperature on the display
