1.Safety Information 1. Safety Information Safety Considerations Before any operations, please read the following safety precautions to avoid any possible bodily injury and prevent damage to this product or any other products connected. To avoid any contingent danger, use this product only as specified. Limit operation to the specified measurement category, voltage, or amperage ratings. Do not use the multimeter if it is damaged. Before you use the multimeter, inspect the case.
1.Safety Information When using the test leads, keep your fingers behind the finger guards on the test leads. Remove the test leads from the multimeter before you open the battery cover. To avoid false readings, which may lead to possible electric shock or personal injury, appears and flashes. replace the battery as soon as the low battery indicator Disconnect circuit power and discharge all high-voltage capacitors before testing resistance, continuity, diodes, or capacitance.
1.Safety Information Measurement Category The multimeter has a safety rating of 1000 V, CAT III. Measurement category definition Measurement CAT I applies to measurements performed on circuits not directly connected to the AC mains. Examples are measurements on circuits not derived from the AC mains and specially protected (internal) mains- derived circuits.

3.Quick Start 3. Quick Start General Inspection After you get a new multimeter, make a check on the instrument according to the following steps: 1. Check whether there is any damage caused by transportation. If it is found that the packaging carton or the foamed plastic protection cushion has suffered serious damage, do not throw it away first till the complete device and its accessories succeed in the electrical and mechanical property tests. 2.
3.Quick Start (2) Lift the tilt stand and loosen the screws with a suitable Phillips screwdriver and remove the battery cover. (3) Observe the battery polarity indicated inside the battery compartment, Insert the batteries. (4) Place the battery cover back in its original position and tighten the screws. Caution: To avoid instruments being damage from battery leakage, always remove the batteries and store them separately if the multimeter is not going to be used for a long period.
3.Quick Start Selecting the Range Auto ranging is set as default when the meter is powered on, When auto ranging is enabled, press In manual range, each additional press of is displayed. to enter the manual range mode. sets the multimeter to the next higher range, unless it is already in the highest range, at which point the range switches to the lowest range. When manual range is enabled, press for more than 2 seconds to enter the auto ranging mode.

3.Quick Start Input terminals The terminal connections for the different measurement functions of the multimeter are described in the table below. Warning: Before starting any measurement, observe the rotary switch position of the multimeter, and then connect the test leads to the correct terminals. Caution: To avoid damaging the multimeter, do not exceed the rated input limit.
4.Making Measurements 4. Making Measurements Measuring AC or DC Voltage Warning: Do not measure any voltage of over 1000 Vdc or 750 Vac rms to avoid instrument damage or electric shock. Do not apply more than 1000 Vdc or 750 Vac rms between the common terminal and the earth ground to avoid instrument damage or electric shock. This multimeter displays DC voltage values as well as their polarity. Negative DC voltages will display a negative sign on the left of the display. DC voltage ranges are 60.
4.Making Measurements Testing Diodes Caution: To avoid possible damage to your multimeter or to the equipment under test, disconnect the circuit power and discharge all high-voltage capacitors before testing diodes. (1) Rotate the rotary switch to . Press once to enter diode testing mode, will be displayed. (2) Connect the black test lead to the terminal and the red test lead to the terminal.
4.Making Measurements Note: For the 4000 uF range, the measuring duration should be over 30 seconds. . Press (1) Rotate the rotary switch to three times to enter capacitance measuring mode, the Farad units will be displayed. (2) Connect the black test lead to the terminal and the red test lead to the terminal. (3) Probe the test points and read the display. Measuring Frequency Frequency ranges are 9.999 Hz, 99.99 Hz, 999.9 Hz, 9.999 kHz, 99.99 kHz, 999.9 kHz, and 9.999 MHz. .
4.Making Measurements (2) Connect the red connection of the K-type thermocouple to the and the black connection to the terminal. (3) Probe the test points and read the display. Press units between or terminal to change the temperature . Measuring DC or AC Current Warning: Never attempt an in-circuit current measurement where the open-circuit potential to earth is greater than 250 V. Doing so will cause damage to the multimeter and possible electric shock or personal injury.
5.Multimeter Features 5. Multimeter Features Data Hold Mode (1) Press to freeze the display during measurement, will be shown on the display. (2) Press again to exit this mode. Note: This function is not available when measuring diodes and transistor. Capturing Max. and Min. Values In MAX mode, the measured maximum value will be held; In MIN mode, the measured minimum value will be held. (1) Press to cycle between the MAX mode and MIN mode. (2) Press for more than 2 seconds to exit the mode.
5.Multimeter Features Buzzer Feature Press the function key, the buzzer will sound “Be…” in short. One minute before Auto Power-off the buzzer will sound “BeBeBeBeBe” five times to warn. Before it is shut off, the buzzer will sound a long ”Beee” then shut off. The buzzer will sound “BeBe…” continuously to warn when the measured DC voltage is higher than 1000 V, AC voltage is higher than 750 V, or the measured DC/AC mV mode is higher than 600.0 mV.
