5. OPERATION
WARNING
Read and understand completely this instruction manual before using the instrument.
Error in operation or in discordance with the warnings and instructions of this manual, can result in material damages
and serious or deadly injuries.
Preparation and Caution Before Measurement
1. Wait at least 30 seconds after power on the instrument before making measurements.
2. The rotary switch must be positioned in the proper measurement function before connecting the test leads to the
device to be tested. Make sure to disconnect the test leads from test points before changing the rotary switch to a new
function or range.
3. If the multimeter is used next to equipment that generates electromagnetic interference, the display can become
unstable or present incorrect values.
4. Do not allow that the instrument enters in contact with water or any another liquid.
5.1 AC / DC Voltage Measurement
WARNING
Do not apply more than 600V DC or AC RMS between the VAHzCxTemp and COM input terminals. Exceed these
limits can result in dangerous electric shock and damage to the instrument.
Take care to avoid contact with the circuit under test, when working with high voltage.
1. Connect the red test lead to the VAHzCxTemp input terminal and the black test lead to the COM input terminal.
2. Set the rotary switch to V position, and press the SEL button to select AC () or DC ().
3. Connect the test leads to the circuit under test. The polarity to DC voltage is automatically displayed. When the
input voltage exceed the range limit, the display will show (OL).
4. Read the measurement in the display.
5.2 AC / DC Current Measurement
1. Connect the red test lead to the VAHzCxTemp input terminal and the black test lead to the COM input terminal to
measure current up to 200mA. To measure current between 200mA and 10A, connect the red test lead to the 10A
input terminal. The maximum measurement time for 10A is 15 seconds.
2. Set the rotary switch to desired current range position (µA for measurements until 4000µA, mA for measurements
until 200mA and 10A, for measurements until 10A).
3. Press the SEL button to select () or DC ().
4. Turn off all power from the circuit under test, and discharge all capacitors before opening the circuit to connect the
multimeter in series with the circuit.
5. Connect the test leads and turn on the power. Make the display reading. The polarity to DC current is automatically
displayed.
5.3 Resistance Measurement
1. Connect the red test lead to the VAHzCxTemp input terminal and the black test lead to the COM input terminal.
2. Set the rotary switch to resistance range position.
To avoid possible damage to the meter or to the equipment under test, disconnect the circuit power and discharge all
high-voltage capacitors before measuring resistance.
3. Connect the test leads to the circuit under test and make the resistance reading in the display.
NOTE:
If the measured resistance exceed the maximum value for the range, the display will show (OL) and will select
the next range. To measure resistance around 1 Mor bigger, the instrument can take some seconds to stabilize the
reading. It is normal to high resistance readings.
5.4 Frequency Measurement
1. Set the rotary switch to frequency position (Hz).
2. Connect the red test lead to the VAHzCxTemp input terminal and the black test lead to the COM input terminal.
3. Connect the test leads to the points to be measured and make the frequency reading in the display.
WARNING
To avoid possible damage to the meter or to the equipment under test, never exceed the measurement limit.
5.5 Capacitance Measurement
WARNING
To avoid possible damage to the meter or to the equipment under test, disconnect the circuit power and make sure all
capacitors are discharged.
1. Set the rotary switch to capacitance position.
2. Connect the red test lead to the VAHzCxTemp input terminal and the black test lead to the COM input terminal.
3. Verify the polarity when necessary and connect the test leads to the capacitor terminals.
4. Read the capacitance measurement in the display.
NOTE:
Before connect the capacitor, the display may show some reading different from zero, however, this reading
must be discarded, because the correct reading will superpose the wrong reading when the capacitor is connected.
5.6 Temperature Measurement
1. Set the rotary switch to °C or °F position.
2. Insert the red test lead of K type thermocouple in VAHzCxTemp input terminal and the black test lead in
COM terminal.
3. Touch the end of temperature sensor to the area or surface of the object to be measured.
4. Make the display reading.
NOTE:
The meter must be keep away from source of very high temperature.
Maximum input voltage in the themperature function: 60V DC or 24V RMS AC.
5.7 Diode Test
1. Connect the red test lead to the VAHzCxTemp input terminal and the black test lead to the COM input terminal.
2. Set the rotary switch to diode position and press the SEL button to select the function.
3. Connect the test leads to the diode. Normally, the forward voltage of a silicon diode is between 0.4V and 0.9V. If the
diode is damaged, the display will show 000 (short-circuit condition) or OL (open condition).
4. Invert the connection of test leads. If the diode is good, OL must be displayed. If it is damaged,
(shortcircuit or resistive), 000 or a near value will be displayed.
