Diode and Continuity

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. Set the range switch to the desired Ve range. It 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 a satisfactory resolution is obtained.
3. Select the “AC/DC” exchange button to select DC or AC function exchange button.
4. Connect the test leads across the load to be measured.
5. Read LCD display. For DC voltage measurement, the polarity of red lead connection will be indicated as well.
   • Note:
   • To avoid damage to the meter, don’t measure a voltage which exceeds 600V DC (for DC voltage measurement) or 600V AC ( for AC voltage measurement).

Measuring Current

1. Connect the black test lead to the “COM” jack. Connect the red test lead to the “(VmA”F” jack if the curent to between 200mA and 10A, connect the a the *10A” jack instead.
2. Set the range switch to desired Are 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 power to the circuit whose current you want to measured. 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 power to the circuit.
7. Read the LCO display. For DC current measurement, the polarity of red lead connection will be indicated as well.

Measuring Resistance

1. Connect the black test lead to the “COM” jack and the
2. Set the range switch to desired range.
3. Connect test leads across the load to be measured.
4. Read the reading on the display.
   • Note:
   • 1. For resistance above 1000k, the meter may take a few seconds to stabilize reading. This is normal for high resistance measuring.
   • 2. When the input is not connected, ie. at open circuit, the figure “1* will be displayed as an over range indication.
   • 3. When measuring in-circuit resistance, be sure the circuit under test has all power removed and all capacitors are fully discharged.

Continuity Test

1. Connect the black lest lead to the “COM” jack and the red test lead to the *OVmA’F* jack ( Note: The polanty of the red lead is positive ***).
2. Set the function switch to »1)) position.
3. Connect the tast leads to the circuit to be measured.
4. If the resistance is lower than approximately 300, the built-in buzzer will sound.

Diode

1. Connect the black test lead to the “COM” jack and the red test lead to the “VmA’F* jack ( Note: The polarity of the red lead is positive *+*).
2. Set the range switch to #+ position.
3. Connect red test lead to the anode of the diode to be tested, and black test lead to the enthode.
4. The display will show the approximate forward voltage of the diode. If the connection is reversed, only figure “1” will be shown on the display.

Measuring Battery

1. Set the range switch to the desired “BATT” range.
2. Connect the red test lead to the “(VmA*F* jack, and the black test lead to the “COM” jack.
3. Connect the test leads to the two terminals of the battery to be measured.
4. Read the voltage value of the battery on the display.

Measuring Temperature

Note: The enclosed Thermerouple is rated to 785*%, when measuring temperatures above 765°F the user must use a thermocouple rated to the higher temperature range. thermocouple to the “COM” jack, the positive (*) plug to the “QVmA’F* jack

1. Set the range switch to the “F” range
2. Connect the negative (-) plug of the K type thermocouple to the “COM” jack,the positive (+) plug to the “QVmA’F” jack
3. Carefully touch the thermocouple to the object to be measured.
4. Wait a while, read the reading on the display.

Detection AC Voltage

Warning

• To avoid electric shock do not touch any conductors with your hand or bare skin.
• Because of the meter’s detection limit, a line (ar conductor) under test may be live even when the built-in buzzer does not sound and the AC voltage detection indicator does not light.
• Before use verify meter’s operation with a known AC voltage
• Do not use the meter in the environment of intense electromagnetic fields.

1. Press and hold down the AC voltage detection button, move the top of the meter to the standard AC outlet to be tested. If the meter detects AC voltage, the built-in buzzer will sound and the AC voltage detection indicator will light.
2. Detect a line Connect a test lead to a terminal jack, connect the probe of this test lead to a line to be tested, press and hold down the AC voltage detection button. If the meter detects AC voltage, the biotin buzzer will sound and the AC voltage detection indicator will light.

BATTERY REPLACEMENT

• When the symbol “+/-“appears on the display, it means that the batteries should be replaced. To replace the batteries, remove the screw on the battery cover, remove the battery cover and replace the old batteries with new batteries of the same type. Reattach the battery cover and reinstall the screw

FUSE REPLACEMENT

• The fuse rarely needs replacement and is usually blown as a result of an operator’s error. This meter uses a fuse: F 500mAL 250V, Fast action To replace the fuse, remove the battery cover and the back cover, replace the damaged fuse with a new fuse of the same ratings, reattach the back cover and reinstall the screws.

MAINTENANCE/CLEANING

• Periodically wipe the case with a damp cloth and mild detergent. Do not use abrasives or solvents

ACCESSORIES

• Owners manual: 1 piece
• Test leads: 1 pair
