4. Read the value on the LCD.
NOTE: When the input is open, "1 " is displayed on the LCD to indicate
overload. For measuring resistance above 1M
Ω
, it may take a few
seconds to get a steady reading. This is normal for high resistance
measurement.
DIODE
1. Plug the black test lead into the "COM" jack and the red test lead into
the "VTemp
Ω
KHz" jack.
2. Set the rotary switch to the " " position.
3. Connect the red test lead to the anode and the black test lead to
the cathode of the diode for testing.
4. Read the value on the LCD.
NOTE: The meter will show approximate forward voltage drop of
the diode.
NOTE: When the test leads are reversed or opened, ' 1' will appear
on the LCD.
CONTINUITY
1. Plug the black test lead into the "COM" jack and the red test lead into
the "VTemp
Ω
Hz" jack.
2. Set the rotary switch to the " " position.
3. Connect the test leads to two ends of the circuit. If resistance of the
circuit is less than 50
Ω ,
the built-in buzzer will sound.
CAPACITANCE
1. Plug the black test lead into the "COM" jack and the red test lead into the
"hFE mA" jack.
2. Set the rotary switch to the position and at the proper range.
WARNING: TO AVOID ELECTRICAL SHOCK AND INJURY POWER OFF THE
CIRCUIT AND DISCHARGE THE CAPACITANCE BEFORE TESTING
CONTINUITY.
