To Verify Continuity:
4. Test for continuity by connecting the meter to the circuit.
5. If the beeper sounds the circuit is complete.

Meter Setup:
Circuit Connection:
Diode Testing:
To ensure a proper functioning diode, the meter will develop a
voltage across the component from a test current. The diode
test function allows measurements of forward voltage drops
across diodes and transistor junctions.
1. Turn off power to the device or circuit that is being tested
To ensure a proper functioning diode, the meter will develop a
voltage across the component from a test current. The diode
test function allows measurements of forward voltage drops
across diodes and transistor junctions.
1. Turn off power to the device or circuit that is being tested
and discharge all capacitors.
2. Plug the leads into the meter inputs as indicated in the fol-
lowing diagram.
3. Select the diode function on the meter.
4. Connect the red rest probe to the anode (+) and the black
4. Connect the red rest probe to the anode (+) and the black
test probe to the cathode (-) of the diode. If the diode is
shunted by a resistor of 1K Ohm or less, it must be
removed from the circuit before taking the measurement.

Example:
1st color band is blue so the first digit is a 6
2nd color band is red so the second digit is a 2
3rd color band is yellow so multiply 62 x 10,000
4th color band is gold so the tolerance is ±5%
2nd color band is red so the second digit is a 2
3rd color band is yellow so multiply 62 x 10,000
4th color band is gold so the tolerance is ±5%
Your Resistor value is 620,000 Ohms (620KΩ)with a tolerance
of ±5%.
