SAFETY INFORMATION

To avoid possible electric shock or personal injury, follow these guidelines:

• a. Do not use the meter if it is damaged. Before you use the meter, inspect the case. Pay particular attention to the insulation surrounding the connectors.
• b. Inspect the test leads for damaged insulation or exposed metal.
• c. Check the test leads for continuity. Replace damaged test leads before you use the meter.
• d. Do not use the meter if it operates abnormally. Protection may be impaired. When in doubt, have the meter serviced.
• e. Do not operate the meter around explosive gas, vapor, or dust.
• f. Do not apply more than the rated voltage, as marked on the meter, between terminals or between any terminal and earth ground.
• g. Before use, verify the meter’s operation by measuring a known voltage.
• h. When measuring currentturnum off the circuit power before connecting the meter in the circuit. Remember to place the meter in series with the circuit.
• i. When servicing the meter, use only specified replacement parts.
• j. Use caution when working above 30V AC RMS, 42V peak, or 60V DC. Such voltages pose a shock hazard.
• k. When using the probes, keep your fingers behind the finger guards on the probes.
• l When making connections, connect the common test lead before you connect the five test leads. When you disconnect test leads, disconnect the live test lead first.
• m. Remove the test leads from the meter before you open the battery cover or the case.
• n. Do not operate the meter with the battery cover or portions of the case removed or loosened.
• o. To avoid false readings, which could lead to possible electric shock or personal injury, replace the batteries as soon as the low battery indicator ( CH”) appears.

OPERATION INTRODUCTION

Measuring Voltage

1. Connect the black test lead to the “COM” jack, and the red test lead to the “QVmA’F* jack.
2. 5et the range switch to the desired Range. If the magnitude of the voltage is not known beforehand, set the range switch to the highest range position, and then reduce it range by range until satisfactory resolution is obtained.
3. Select the “AC/DC” exchange button to select the DC or AC function exchange button.
4. Connect the test leads across the load to be measured.
5. Read the LCD. For DC voltage measurement, the polarity of the red lead connection will be indicated as well.

Measuring Current

1. Connect the black test lead to the “COM” jack. Connect the red test lead to the “QVMAF” jack if the current to be measured is less than 200mA. If the current is. between 200mA and 10A , connect the red test lead to the *10A” jack instead.
2. Set the range switch to the desired A-range. If the magnitude of the current is not known beforehand, set the range switch to the highest range position and then reduce it range by range until satisfactory resolution is obtained.
3. Press the “AC/DC” exchange button to select DC or AC function.
4. Turn off the power to the circuit whose current you want to measure. Discharge all high-voltage capacitors of the circuit.
5. Break the current path to be tested. Connect the red test lead to the more positive side of the break and the black test lead to the more negative side of the break.
6. Turn on the power 10 tto he circuit.
7. Read the LCD. For DC measurement, the. The polarity of the red lead connection will be indicated as well.

Measuring Resistance
