Warning

• To avoid possible electric shock or personal injury, and to avoid possible damage to the Meter or to the equipment under test, adhere to the following rules:
• Before using the meter inspect the case. Do not use the meter if it is damaged or the case (or part of the case) is removed. Look for cracks or missing plastic. Pay attention to the insulation around the connectors.
• Inspect the test leads for damaged insulation or exposed metal. Check the test leads for continuity.
• Do not apply more than the rated voltage, as marked on the Meter, between the terminals or between any terminal and grounding.
• The rotary switch should be placed in the right position and any changeover of range shall be made during measurement to prevent damage to the Meter.
•  When the meter is working at an effective voltage over 60V in DC or 36V RMS in AC, special care should be taken since there is a danger of electric shock.
• Use the proper terminals, function, and range for your measurements.
• Do not use or store the meter in an environment of high temperature, humidity, explosive, inflammable, and strong magnetic field. The performance of the meter may deteriorate after being dampened.
• When using the test leads, keep your fingers behind the finger guards.
• Disconnect circuit power and discharge all high-voltage capacitors before testing resistance, continuity, or diodes.
• Replace the battery as soon as the battery indicator appears. With a low battery, the meter might produce false readings that can lead to electric shock and personal injury.
• Remove the connection between the testing leads and the circuit being tested, and turn the meter power off before opening the meter case.
• When servicing the meter, use only the same model number or identical electrical specifications replacement parts.
• The internal circuit of the meter shall not be altered at will to avoid damage to the meter and any accident.
• Soft cloth and mild detergent should be used to clean the surface of the meter when servicing. No abrasive or solvent should be used to prevent the surface of the meter from corrosion, damage, and accident.
• The meter is suitable for indoor use.
• Turn the meter power off when it is not in use, and take out the battery when not using it for a long time. Constantly check the battery as it may leak when it has been used for some time, and replace the battery as soon as leaking appears.
• A leaking battery will damage the Meter.

OPERATION INSTRUCTION

Measuring Voltage

1. Connect the BLACK test lead to the “COM” jack and the RED to the “INPUT” jack.
2. Set the function switch to range position.
3. Connect the test leads across the source or load to be measured.
4. Press the SEL button, to select or range
5. Read LCD display. The polarity of the RED lead connection will be indicated when making a DC measurement.

Note:

• a. In small range, the meter may display an unstable reading when the test leads have not been connected to the load to be measured. It is normal and will not affect the measurements.
• b. To avoid damage to the meter, don’t measure a voltage which exceeds 600Vdc (for DC voltage measurement) or 600Vac (for AC voltage measurement).

Measuring Current

1. Set Function/Range Switch to the A~ range.
2. Press the trigger to open the transformer jaws and clamp one conductor only it is impossible to make measurements when two or three conductors are clamped at the same time.
3. Display reading is flowing the conductor AC current.
