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
In case the device is going to be unused for an extended period of time, remove the
batteries to prevent them from draining
Expired or damaged batteries can cause cauterization on contact with the skin. Always,
therefore, use suitable hand gloves in such cases
See that the batteries are not short-circuited. Do not throw batteries into the fire.

AC/DC Current Measurements
WARNING: Disconnect the test leads before measuring with clamp.
1. Rotate the Function switch to the 1500AAC/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 400AAC/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 ADC, and, with no conductor in the jaw, press the
ZERO button. The display will show zero. The offset value is now stored and removed
from all measurements.
Frequency
When ACV is selected, the measured frequency can be viewed in the lower display.
AC/DC Voltage Measurements
CAUTION: Do not measure voltages if a motor on the circuit is being switched ON or OFF.
Large voltage surges may occur that can damage the meter.
1. Rotate the function switch to the V position.
2. Press the MODE button to select AC or DC Voltage.
3. Insert the black test lead banana plug into the negative COM jack.
Insert the red test lead banana plug into the positive V 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.

2. Press the MODE button to select diode test .
3. Touch the test probe tips to the diode or semiconductor junction under test. Note the
meter reading.
4. Reverse the test lead polarity by reversing the red and black leads. Note this reading.
5. The diode or junction can be evaluated as follows:
If one reading displays a value (typically 0.400V to 01.800V) and the other reading
displays OL, the diode is good.
If both readings display OL the device is open.
If both readings are very small or „0‟, the device is shorted.
