KMD 05
Digital multimeter
Warning
Check fuses before making current measurements. Make sure to use
correct input jacks to prevent damage to the meter.
Resistance measurement
• Turn off power power to the circuit. Allow all capacitors to discharge.
• Set the rotary switch to the multifuction position. The default fuction is
resistance.
• Connect the red test lead to the input jack and the black lead to the COM
jack.
• Connect the leads to the circuit under test and read the measurement on
the display.
Tips for measuring resistance:
• In-circuit resistance is usually different from a resistors rating due to the
fact that the meter’s test current flows in parallel with the circuit.
• For increased accuracy when measuring low resistances, short the test
leads, record the value displayed, then connect the leads to the circuit and
substract the shorted value from the circuit measurement.
• When the leads are disconnected from the circuit under test, OL will be
displayed on the screen.
Warning
To prevent injury or damage to the meter, turn off power to circuit and
discharge all capacitors fully before making resistance mesurements.
Continuity mesurement
• Turn off power power to the circuit. Allow all capacitors to discharge.
• Set the rotary switch to the multifuction position. Press
FUNC twice to
enter continuity mode.
• Connect the red test lead to the input jack and the black lead to the COM
jack.
• Connect the leads to the circuit under test. If the measured resistance is
less than 30Ω, the buzzer will sound.
