SAFETY INFORMATION
The following safety information must be observed to insure maximum personal safety during the operation at this meter:
Do not use the meter if the meter or test leads look damaged, or if you suspect that the meter is not operating properly.
Never ground yourself when taking electrical measurements. Do not touch exposed metal pipes, outlets, fixtures, etc., which might be at ground potential. Keep your body isolated from ground by using dry clothing, rubber shoes, rubber mats, or any approved insulating material.
Turn off power to the circuit under test before cutting, unsoldering, or breaking the circuit.
Small amounts of current can be dangerous.
Use caution when working above 60V dc or 30V ac rms. such voltages pose a shock hazard.
When using the probes, keep your fingers behind the finger guards on the probes.
Measuring voltage which exceeds the limits of the multimeter may damage the meter and expose the operator to a shock hazard. Always recognize the meter voltage limits as stated on the front of the meter.
Never apply voltage or current to the meter that exceeds the specified maximum:

OPERATION
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. This meter
has Auto OFF that automatically shuts the meter
2.
OFF if 15 minutes elapse between uses.
If “OL” 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.
AUTORANGING/MANUAL RANGE SELECTION
When the meter is first turned on, it automatically goes into Autoranging. This automatically selects the best range for the measurements being made and is generally the best mode for most measurements. For measurement situations requiring that a range be manually selected, perform the following:
1. Press the RANGE key. The “AUTO” display indicator will turn off or select diode /beeper, AC/DC Clamp
2. Press the RANGE key to step through the available ranges until you select the range you want.
3. To exit the Manual Ranging mode and return to
Autoranging, press and hold the RANGE key for 2 seconds.
Note: Manual ranging does not apply for the Frequency functions.
“min” occurs.
3. To exit MAX/MIN mode press and hold the
MAX/MIN key for 2 seconds
DISPLAY BACKLIGHT
Press and hold the HOLD key for >1 second to turn on or off the display backlight function. The backlight will automatically turn off after 10 seconds.
HOLD
The hold function freezes the reading in the display. Press the HOLD key momentarily to activate or to exit the
HOLD function.
NON-CONTACT VOLTAGE (NCV)
The NCV function works on any rotary switch position.
1.Test the detector on a known live circuit before use.
2.Hold the top of the meter very close to the voltage source as shown.
3.If voltage is present, the rim of the LCD display will flash a bright red and a motor shaking will happen.
Hz/duty
1. Switch to Hz range.
2. Press the Hz button to show the reading in the display and the "Hz" indicator will appear on the display.
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.
MAX/MIN
Note: When using the MAX/MIN function in
Autoranging mode, the meter will “lock” into the range that is displayed on the LCD when
MAX/MIN is activated. If a MAX/Min reading exceeds that range, an “OL” will be displayed.
Select the desired range BEFORE entering
MAX/MIN mode.
1. Press the MAX/MIN key to activate the MAX/MIN recording mode. The display icon "MAX" will appear.
The meter will display and hold the maximum reading and will update only when a new “max” occurs.
2. Press the MAX/MIN key again and the display icon
"MIN" will appear. The meter will display and hold the minimum reading and will update only when a new
1. Set the function switch to the V DC position .
2. Insert the black test lead banana plug into the negative
(COM) jack and the red test lead banana plug into the positive (V) jack.
3. Touch the test probe tips to the circuit under test. Be sure
4. to observe the correct polarity (red lead to positive, black lead to negative).
Read the voltage in the display. 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 0 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 V AC position.
2. Insert the black test lead banana plug into the negative (COM) jack and the red test lead banana plug into the positive (V) jack.
3. Touch the test probe tips to the circuit under test.
4. Read the voltage in the display. The display will indicate the proper decimal point, value and symbol (AC, V, etc.).
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 DC current measurements, set the function switch to the DC 10A position and insert the red test lead banana plug into the 10A jack.

4. 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.
5. Apply power to the circuit.
6. Read the current in the display. The display will indicate the proper decimal point, value and symbol.
AC CURRENT MEASUREMENTS
WARNING: To avoid electric shock, do not measure
AC current on any circuit whose voltage exceeds 250V
AC.
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.

4. Touch the black test probe tip to the negative side of the circuit. And touch the red test probe tip to the positive side of the circuit.
5. Apply power to the circuit.
6. Read the current in the display. The display will indicate the proper decimal point, value and symbol.
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 position.
2. Insert the black test lead banana plug into the negative
(COM) jack and the red test lead banana plug into the positive jack.
3. Touch the test probe tips across the circuit or part under test. It is best to disconnect one side of the part under test so the rest of the circuit will not interfere with the resistance reading.
4. Read the resistance in the display. The display will indicate the proper decimal point, value and symbol.
CONTINUITY CHECK
WARNING: To avoid electric shock, never measure continuity on circuits or wires that have voltage on them.
