measuring resistance

1. Connect the black test lead to the "com" terminal and the red test lead to the "
terminal.
2. Set the rotary switch to Ω position.
3. Connect the test leads across the object to be tested.
4. Read the reading on the display.
Note:
1. For measurements > 1M Ω, it may take several seconds for the reading to stabilize. It is
normal for high resistance measurements.
2. If the input terminals are open, overrange indicator "OL"will be displayed on the display.
3. Before measurement, disconnect all power to the circuit to be tested and discharge all
capacitors thoroughly.

measuring temperature

Note:
To avoid possible damage to the meter or other equipment, remember that while
the meter is rated for -20°C to +1000°C, the K Type Thermocouple provided with the meter
is rated to 250°C. For temperatures out of that range, use a higher rated thermocouple.
The K Type Thermocouple provided with the meter is a present, it is not professional and
can only be used for non-critical reference measurements. For accurate measurements, use
a professional thermocouple.
1 Connect the negative "
and the positive " + " plug of this thermocouple to the "
2 Set the rotary switch to °C position.
3 Connect the sensing end of the thermocouple to the object to be tested.
4 Wait a while, then read the reading on the display.
Warning
To avoid electric shock and personal injury, do no make measurement on any
live conductor

Diode test

1. Connect the black test lead to the "com" terminal and the red test lead to the "
terminal. ( The red test lead is positive" + ". )
2. Set the rotary switch to the "
until the symbol "
3. Connect the red test lead to the anode of the diode to be tested and the black test lead
to the cathode of the diode.
4. Read the approximate forward voltage drop of the diode on the display.

continuity test

1. Connect the black test lead to the "com" terminal and the red test lead to the "
terminal.
2. Set the rotary switch to the "
until the symbol " " appears on the display.
3. Connect the test leads across the circuit to be tested.
4. If the resistance is less than about 30Ω, the built-in buzzer will sound.
Note : Before test, disconnect all power to the circuit to be tested and discharge all
capacitors thoroughly.
