  WARNING
  To avoid possible electric shock or personal injury, and possible damage to the Digital multimeter or the equipment under test, follow the following rules:

• Before using the Digital multimeter inspect the case. Do not use the multimeter if damaged or part of the case has been removed. Look for cracks or missing plastic Double check insulation around the connectors.

• Inspect the test probes for damaged insulation or exposed metal. Check the test probes have continuity.

• Do not apply more than the rated voltage as marked on the multimeter, between the terminals or between any terminal and grounding.

• To prevent damage, the rotary switch must be placed in the correct position and there must be no changes while the measurement is being carried out.

• Special care should be taken when the multimeter is working at an effective voltage higher than 60 V in DC or 30 V RMS AC, as there is a danger of electric shock.

• Use the appropriate terminals, functions and range for the measurements.

• Do not use or store the multimeter in high temperature, humid environments, near explosive and flammable products and strong magnetic fields are present.

• The performance of the multimeter may deteriorate after it gets wet.

• When using test probes keep fingers behind the fingers guard.

• Disconnect the feeding circuit and discharge all the high voltage capacitors before testing resistance, continuity and diodes.

• Replace the battery as soon as the battery indicator “ ” appears. With a low battery, the multimeter might produce false readings that can lead to electric shock and personal injury.

• Remove the connection between the test probes and the circuit being tested. Turn off the power to the multimeter before opening its housingWhen servicing the multimeter use only replacement parts of the same model number or electrical specifications.

• The internal circuit of the multimeter must not be altered at will to avoid damaging it or having an accident.

• Soft cloth and mild detergent should be used to clean the surface or the multimeter when servicing. No abrasive and solvent should be used to prevent the surface of the Digital multimeter from corrosion, damage and accident.

• The multimeter is suitable for indoor use.

• Turn the multimeter power off when it is not in use and take out the battery when not using for a long time. Constantly check the battery as it may leak when it has been used for a long time. Replace the battery immediately if leaking appears. A leaking battery will damage the multimeter.

OPERATION INSTRUCTIONS

VOLTAGE MEASUREMENT

1. Plug the BLACK test probe into the “COM” connector and the RED test probe into the “V” connector.
2. Set the rotary knob to the voltage position; select the type of voltage you wish to measure V AC or V DC
3. Connect the probes through the measured source or load.
4. Read the LCD display, the polarity of the RED probe connection will indicate when a dc measurement is made.

NOTE

• In a small mV range example, the multimeter may show an unstable reading when the probes have not been connected to the load to be measured. This is normal and will not affect the measurement.
• To avoid damage to the multimeter, do not measure a voltage exceeding  600 V (for DC voltage measurements) or 600 V (for AC measurement under CAT III conditions and 1000 V for DC voltage) 750 V (for AC voltage) under CAT II conditions

CURRENT MEASUREMENT

1. Set the switch Function / Range, in the range 60 A / 600 A /1 000 A
2. Pull the trigger to open the transfer clamps and hold only one conductor as it is not possible to make measurements when two or three conductors are held at the same time.
3. The reading on the display shows the current of the AC conductor.

RESISTANCE MEASUREMENT

1. Connect the BLACK test probe to the “COM” connector and the RED to the ( **) connector (Note:** The polarity of the red test probe is positive “+”).
2. Set the function switch to the range “ “
3. Press the “RANGE” button and the measurement can be selected manually.
4. Press the “SELECT” button to select the resistance mode measurement. The symbol “MΩ” appears as an indicator.
5. Connect the test probes through the load to be measured.
6. Read the reading on the display.

NOTE

• For resistance measurements >1 M, it takes the multimeter a few seconds to stabilize the reading. This is normal for high resistance measurements.
• When the power input is not connected, e.g. in open circuit, the symbol “OL” will be displayed as an overrange indicator.
• Before measuring the in-circuit resistance, confirm that the circuit being tested has all power removed and that all capacitors are completely discharged.

AUDIBLE CONTINUITY TEST

1. Connect the black test probe to the “COM” connector and the RED to the “ **” connector. (Note:** The polarity of the red test probe is positive “+”).
2. Set the function switch to the “ ” range.
3. Press the “SELECT” button to select the audible continuity test selection mode. The “ ” symbol will appear as an indicator.
4. Connect the test probes through the load to be measured.
5. If the circuit resistance is less than 30 Ω , the interlocked buzzer will buzz.

DIODE TEST

1. Plug the BLACK test probe into the “COM” connector and the RED connector into ” **“. (Note:** The polarity of the red test probe is positive “+”.
2. Set the function switch to the “ ” range
3. Press the “SELECT” button to select the continuity measurement mode. The symbol ” ” will appear as an indicator.
4. Connect the red test lead to the anode of the diode to be tested and the black test probe to the cathode.
5. The multimeter will show the direct voltage of the diode. If the connections are reversed, “OL” will be shown on the display.

TEMPERATURE MEASUREMENT

1. Set the function range switch to the “TEMP” position.
2. Confirm that the polarity of the thermocouple probe is correct; place the cold end (free end) of the thermocouple probe in the terminal (black on the “COM” connector and red on the “ºC” connector).
3. Place the thermocouple on or in the object to be tested.
4. The temperature value is shown on the display in degrees Celsius (ºC).
5. Press the “SELECT” button, Fahrenheit and Celsius to convert the values.

CAPACITANCE MEASUREMENT

1. Plug the BLACK test lead into the “COM” connector and the RED test lead into the “ ****” connector.
2. Set the function switch ” ” to the position. (NOTE: The polarity of the RED test probe is positive “+”).
3. Connect the test leads through the capacitor being measured and confirm that the polarity of the connection is correct.

When the capacitance being measured is above 100 µF, it needs at least 5 seconds to stabilize the reading.
FREQUENCY MEASUREMENT (Automatic Range)
NOTE

1. Set the range function switch to the required “Hz / Duty” position.

2. Plug the BLACK test probe into the “COM” connector and the RED test probe into the “ **” connector.
   Note:** Test probe polarity is positive (“+”).

3. Connect the test probes through the load to be measured.

NOTE
Do not apply more than 250 V RMS at the input. Voltages higher than 100 V RMS may be indicated, but the reading may be out of range. While using the clamp to test AC current, press the ” ” button and open the clamp, the multimeter will display the frequency of the measured current.
NOTE

• The test temperature is displayed when the thermocouple probe is placed in the test holes.
• The surrounding temperature is displayed when the sensor circuit is cut off.
• The temperature limit measured by the thermocouple probe together with the multimeter is 400 ºC maximum in short periods, in case you need to measure higher temperatures you should acquire a thermocouple probe with a higher capacity.

AUTOMATIC SHUT OFF

If the multimeter is not operated for about 15 minutes, it turns off automatically. To turn it back on, just turn the range switch
