SAFETY INSTRUCTIONS

This meter has been designed for safe use, but must be operated with caution. The rules listed below must be carefully followed for safe operation.

1. NEVER apply voltage or current to the meter that exceeds the specified maximum:
2. USE EXTREME CAUTION when working with high voltages.
3.  DO NOT measure voltage if the voltage on the “COM” input jack exceeds 500V above earth ground.
4.  NEVER connect the meter leads across a voltage source while the function switch is in the current, resistance, or diode mode. Doing so
   can damage the meter.
5.  ALWAYS discharge filter capacitors in power supplies and disconnect the power when making resistance or diode tests.
6. ALWAYS turn off the power and disconnect the test leads before opening the doors to replace the fuse or batteries.
7. NEVER operate the meter unless the back cover and the battery and fuse doors are in place and fastened securely

BATTERY INSTALLATION

WARNING: To avoid electric shock, disconnect the test leads from any source of voltage before removing the battery door.

1. Disconnect the test leads from the meter.
2.  Remove the protective rubber holster (if installed)
3.  Open the battery door by loosening the screw using a Phillips head screwdriver.
4. Insert the battery into battery holder, observing the correct polarity.
5.  Put the battery door back in place. Secure with the screw

WARNING: To avoid electric shock, do not operate the meter until the battery door is in place and fastened securely.

NOTE: If your meter does not work properly, check the fuses and batteries to make sure that they are still good and that they are properly inserted

OPERATING INSTRUCTIONS

WARNING: Risk of electrocution. High-voltage circuits, both AC and DC, are very dangerous and should be measured with great care

1. ALWAYS turn the function switch to the OFF position when the meter is not in use.
2.  If “1” appears in the display during a measurement, the value exceeds the range you have selected. Change to a higher range.
   NOTE: On some low AC and DC voltage ranges, with the test leads not connected to a device, the display may show a random, changing reading. This is normal and is caused by the high-input sensitivity. The reading will stabilize and give a proper measurement when connected to a circuit.

DC VOLTAGE MEASUREMENTS
CAUTION: Do not measure DC voltages if a motor on the circuit is being switched ON or OFF. Large voltage surges may occur that can damage the meter

1. Set the function switch to the highest V DC position.
2. Insert the black test lead banana plug into the negative (COM) jack. Insert the red test lead banana plug into the positive (V) jack.
3. Touch the black test probe tip to the negative side of the circuit. Touch the red test probe tip to the positive side of the circuit.
4. Read the voltage in the display. Reset the function switch to successively lower V DC positions to obtain a higher resolution reading. The display will indicate the proper decimal point and value. If the polarity is reversed, the display will show(-) minus before the value.

AC VOLTAGE MEASUREMENTS
WARNING: Risk of Electrocution. The probe tips may not be long enough to contact the live parts inside some 240V outlets for appliances because the contacts are recessed deep in the outlets. As a result, the reading may show O volts when the outlet actually has voltage on it. Make sure the probe tips are touching the metal contacts inside the outlet before assuming that no voltage is present.

CAUTION: Do not measure AC voltages if a motor on the circuit is being switched ON or OFF. Large voltage surges may occur that can damage the meter.

1. Set the function switch to the highest V AC position.
2.  Insert the black test lead banana plug into the negative (COM) jack.Insert red test lead banana plug into the positive (V) jack.
3. Touch the black test probe tip to the negative side ofthe circuit. Touch the red test probe tip to the positive side of the circuit.
4. Read the voltage in the display. Reset the function switch to successively lower V AC positions to obtain a higher resolution reading. The display will indicate the proper decimal point and value.

DC CURRENT MEASUREMENTS
CAUTION: Do not make current measurements on the 10A scale for longer than 30 seconds. Exceeding 30 seconds may cause damage to the meter and/or the test leads.

1. Insert the black test lead banana plug into the negative (COM) jack.
2.  For current measurements up to 200mA DC, set the function switch to the 200mA DC position and insert the red test lead banana plug into the (mA) jack.
3. For current measurements up to 1 0A DC, set the function switch to the 1 0A range and insert the red test lead banana plug into the (1 0A) jack.
4. Remove power from the circuit under test, then open up the circuit at the point where you wish to measure current.
5. Touch the black test probe tip to the negative side of the circuit. Touch the red test probe tip to the positive side of the circuit.
6. Apply power to the circuit.
7. Read the current in the display. The display will indicate the proper decimal point and value

AC CURRENT MEASUREMENTS
CAUTION: Do not make current measurements on the 10A scale for longer than 30 seconds. Exceeding 30 seconds may cause damage to the meter and/or the test leads.

1. Insert the black test lead banana plug into the negative (COM) jack.
2. For current measurements up to 200mA AC, set the function switch to the 200m AAC position and insert the red test lead banana plug into the (mA) jack.
3. For current measurements up to 1 0A AC, set the function switch to the 1 0A range and insert the red test lead banana plug into the (1 0A) jack.
4.  Remove power from the circuit under test, then open up the circuit at the point where you wish to measure current.
5. Touch the black test probe tip to the negative side of the circuit. Touch the red test probe tip to the positive side of the circuit.
6. Apply power to the circuit.
7.  Read the current in the display. The display will indicate the proper decimal point and value.

RESISTANCE MEASUREMENTS
WARNING: To avoid electric shock, disconnect power to the unit under test and discharge all capacitors before taking any resistance measurements. Remove the batteries and unplug the line cords.

1. Set the function switch to the highest o position.
2. Touch the test probe tips across the circuit or part under test.
3. It is best to disconnect one side of the part under test so the rest of the circuit will  interfere with the resistance reading.
4. Read the resistance in the display and then set .the function switch to the lowest o position that is  greater than the actual or any anticipated resistance.
5. The display will indicate the proper decimal point and value.

CONTINUITY CHECK
WARNING: To avoid electric shock, never measure continuity on circuits or wires that have voltage on them

1. Set the function switch to the position.
2.  Insert the black lead banana plug into the negative (COM) jack
3. Insert the red test lead banana plug into the positive (0) jack.
4. Touch the test probe tips to the circuit or wire you wish to check.  If the resistance is less than approximately 300, the audible signal will
   sound. If the circuit is open, the display will indicate “1 “.

DIODE TEST

1. Insert the black test lead banana plug into the negative COM jack and the red test lead banana plug into the positive diode jack.
2. Turn the function switch to the j)i+ / •))) position.
3. Touch the test probes to the diode under test. Forward voltage will indicate 400 to 700mV. Reverse voltage will indicate “1 “. Shorted devices will indicate near 0mV. Shorted devices will indicate near 0mV and an open device will indicate “1 ” in both polarities.

BATTERY TEST

1.  Insert the black test lead banana plug into the negative COM jack and the red test lead banana plug into the positive V jack.
2.  Select the 1.5V or 9V BAT position using the function switch.
3. Connect the red test lead to the positive side of the 1.5V or 9V battery and the black test lead to the negative side of the 1.5V or 9V battery.
4.  Read the voltage in the display.

MAINTENANCE

WARNING
To avoid electric shock, disconnect the test leads from any source of voltage before removing the back cover or the battery or fuse doors.

WARNING
To avoid electric shock, do not operate your meter until the battery and fuse doors are in place and fastened securely.
