This meter is a compact 3 1/2-digit digital automotive multimeter. In addition to the features of a normal multimeter, it can also be used to measure RPM, dwell angle, duty cycle, battery, temperature, ignition system, and etc. It is very useful and is an ideal measurement tool for automotive repair
and service.

1. Connect the black test lead to the " COM " jack and the red test lead to the " INPUT " jack. 2. Set the range switch to desired range. 3. Connect the test leads across the circuit or source to be measured. 4. Read the reading on the display. The polarity of the red lead connection will be indicated as well. Note : To avoid damages to the meter, do not attempt to measure a DC voltage higher than 35V although readings may be obtained. |
1. Connect the black test lead to the " COM " jack and the red test lead to the " 10A " jack. 2. Set the range switch to position. 3. Turn off power to the circuit which you want to measure. Discharge all capacitors. 4. Break the circuit path to be measured, connect the test leads in series with the circuit. 5. Turn on power to the circuit, then read the display. The polarity of the red test lead connection will be indicated as well. |
1. Connect the black test lead to the " COM " jack and the red test lead to the " INPUT " jack. ( Note:The polarity of the red lead is positive " + ". ) 2. Set the range switch to desired range. 3. Connect the test leads across the load to be measured. 4. Read the reading on the display. |
1. Connect the black test lead to the " COM " jack and the red test lead to the " INPUT " jack. ( Note:The polarity of the red lead is positive " + ". ) 2. Set the range switch to position. 3. Connect the test leads to the circuit to be measured. 4. If the resistance is less than about 30 , the built-in buzzer will sound. |

1. Connect the black test lead to the " COM " jack and the red test lead to the " INPUT " jack. 2. Set the range switch to 20kHz position. 3. Connect the test leads across the source or load to be measured. 4. Read the reading on the display. |
1. Connect the black test lead to the " COM " jack and the red test lead to the " INPUT " jack. ( Note:The polarity of the red lead is positive " + ". ) 2. Set the range switch to position. 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. The display shows the approximate forward voltage drop of the diode. If the connection is reversed, "1" will be shown on the display. |
1. Connect the black test lead to the " COM " jack and the red test lead to the " INPUT " jack. 2. Set the range switch to Duty position. 3. Connect the red test lead to the positive terminal of the signal source be measured and the black test lead to the negative terminal of the signal source. 4. Read the reading on the display. |
1. Connect the negative " - " plug of the K type thermocouple to the " COM " jack and the positive " + " plug of the K type thermocouple to the " INPUT " jack. 2. Set the range switch to °C position. 3. Connect the sensing end of the thermocouple to the object to be measured. 4. Wait until the reading is stable, then read the reading. |

1. Connect the black test lead to the " COM " jack and the red test lead to the " INPUT " jack. 2. Set the range switch to desired DWELL position according to the cylinder number of the engine to be measured. 3. Connect the black test lead to ground or the negative terminal of the battery, and connect the red test lead to the low voltage terminal of the distributor or the negative terminal of the ignition coil. 4. Start the engine and read the reading on the display. |
1. Connect the black test lead to the " COM " jack and the red test lead to the " INPUT " jack. 2. Set the range switch to desired TACH position according to the cylinder number of the engine to be measured. 3. Connect the black test lead to ground or the negative terminal of the battery, and connect the red test lead to the low voltage terminal of the distributor or the negative terminal of the ignition coil. 4. Start the engine. Read the reading on the display and then multiply this reading by 10 to get the final measurement result. |
1. Connect the black test lead to the " COM " jack and the red test lead to the " INPUT " jack. 2. Set the range switch to desired BAT. position according to the rated voltage of the battery to be tested. 3. Connect the black test lead to the negative terminal of the battery and the red test lead to the positive terminal of the battery. 4. If the " Low " LED lights, the battery is low. If the " Normal " LED lights, the battery is normal. If the " High " LED lights, the battery is high. |
1. Connect the red test lead to the " INPUT " jack. 2. Set the range switch to HV position. 3. Make sure that the engine is running, then place the steel probe of the test lead on cylinder 1s insulated spark plug wire. 4. If the " HV " LED flashes, the spark plug wire is delivering spark. Repeat the test for the other cylinders. |
