discharge.
• Set the rotary switch to the multi-function 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 30
Ω , the buzzer will
sound.
Turn off power to the circuit. Allow all capacitors to
WARNING
To prevent injury or damage to the meter,turn off
power to circuit and discharge all capacitors fully
before making continuity measurements.
4.5 Diode test
• Turn off power to the circuit. Allow all capacitors to
discharge.
• Set the rotary switch to the multi-function position.
Press “
FUNC ” once to enter diode mode.
• Connect the red test lead to the input jack and the black
lead to the COM jack.
• Connect the red test lead to the anode (+) and the black
lead to the cathode (-) of the diode and read the
measurement on the display. The meter will display
“OL” if the connection is reversed.
WARNING
To prevent injury or damage to the meter,turn off
power to circuit and discharge all capacitors fully
before making
diode measurements.
4.6 Battery test
•
• Connect the red test lead to the input jack and the black
lead to the COM jack.
• Connect the red test lead to the positive (+) end and the
black lead to the negative (-) end of the battery and read
the measurement on the display. Set the rotary switch to the appropriate battery test range.
4.7 Temperature measurement
•
Press “
FUNC ” to switch between Celsius and Fahrenheit.
• Connect the positive end of the K-type thermocouple to
the input jack and the negative end to the COM jack.
• Place the tip of the thermocouple to the surface of the
object to be tested and read the measurement on the
display.
Set the rotary switch to the temperature position.
To prevent injury or damage to the meter,do not
connect the meter to a battery with a voltage rating
exceeding 60V AC or 30V DC
WARNING
To avoid injury or damage to the meter,do not move
the rotary switch to the temperture position while
measuring
voltages exceeding 30V
