SAFETY NOTES
• Do not exceed the maximum allowable input range of any function.
• Do not apply voltage to meter when resistance function is selected.
• Set the function switch OFF when the meter is not in use.
• Remove the battery if meter is to be stored for longer than 60 days.
WARNINGS
• Set function switch to the appropriate position before measuring.
• When measuring volts do not switch to current/resistance modes.
• Do not measure current on a circuit whose voltage exceeds 600V.
• When changing ranges, always disconnect the test leads from the circuit under test.
CAUTIONS
• Improper use of this meter can cause damage, shock, injury or death. Read and understand this user manual before operating the meter.
• Always remove the test leads before replacing the battery or fuses.
• Inspect the condition of the test leads and the meter itself for any damage before operating the meter. Repair or replace any damage before use.
• Use great care when making measurements if the voltages are greater than 25VAC rms or 35VDC. These voltages are considered a shock hazard.
• Always discharge capacitors and remove power from the device under test before performing Diode, Resistance or Continuity tests.
• Voltage checks on electrical outlets can be difficult and misleading because of the uncertainty of connection to the recessed electrical contacts. Other means should be used to ensure that the terminals are not "live".
• If the equipment is used in a manner not specified by the manufacturer, the protection provided by the equipment may be impaired.
• This device is not a toy and must not reach children’s hands. It contains hazardous objects as well as small parts that the children could swallow. In case a child swallows any of them, please contact a physician immediately
• Do not leave batteries and packing material lying around unattended; they can be dangerous for children if they use them as toys
• Expired or damaged batteries can cause cauterization on contact with the skin.
Always, therefore, use suitable hand gloves in such cases
• Do not short-circuited the battery. Do not throw batteries into a fire.

Operation
NOTES: Read and understand all Warning and Caution statements in this operation manual prior to using this meter. Set the function select switch to the OFF position when the meter is not in use.
Non-Contact Voltage Detector
WARNING: Risk of Electrocution. Before use, always test the Voltage Detector on a known live circuit to verify proper operation.
1. Rotate the Function switch to any measurement position.
2. Place the detector probe tip on the conductor to be tested.
3. If AC voltage is present, the NCV detector will turn on with a steady red light.
NOTE: The conductors in electrical cord sets are often twisted.
For best results, move the probe tip along a length of the cord to assure placing the tip close to the live conductor.
NOTE: The detector is designed with high sensitivity. Static electricity or other sources of energy may randomly trip the sensor. This is normal operation.
AC/DC Current Measurements
WARNING: Disconnect the test leads before measuring with clamp.
1. Rotate the Function switch to the 1500A
AC/DC position.
2. Press the MODE button to select AC or DC.
3. Press the trigger to open jaw. Fully enclose only one conductor.
4. Read the current value in the display.
5. If the value is less than 400A, rotate the function switch to the 400A
AC/DC
position to improve resolution.
DCA Zero
The Zero feature removes offset values and improves accuracy for DC current measurements. To perform a zero, select DC and, with no conductor in the jaw, press
6 MA1500 -EN-V1.2-4/11
the ZERO button. The display will show approxemately zero. The offset value is now stored and removed from all measurements.
Frequency
When ACA is selected, the measured frequency can be viewed in the lower display.
7 MA1500 -EN-V1.2-4/11

1. Set the function switch to the 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. Press the MODE button to select (diode).
4. Touch the test probe tips to the diode or semiconductor junction under test. Note the meter reading.
5. Reverse the test lead polarity by reversing the red and black leads. Note this reading.
6. The diode or junction can be evaluated as follows:
8 MA1500 -EN-V1.2-4/11
ß If one reading displays a value (typically 0.400V to 01.800V) and the other reading displays OL, the diode is good.
ß If both readings display OL the device is open.
ß If both readings are very small or ‘0’, the device is shorted.
9 MA1500 -EN-V1.2-4/11
