2. OPERATION
Before taking any measurements, read the safety information
section Always examine the instrument for damage, contamination
(excessive dirt, grease, ect.) and defects. Examine the test leads
for cracked or trayed insulation. If any abnormal conditions exist
do not make any measurements.
MAX. DATA HOLD SWITCH
The push switch (push Latch, Push Release) will hold the maximum
reading on the display. The display will update if a higher value is
measured. A “p” will appear in the display when this feature is
enabled.”
2.1 Current Measurements
1. Set the Function/Range switch on the highest 600A AC range.
2. Press the trigger to open transformer jaws and clamp onto one
conductor only. Read the current directly on the display. It is
recommenced that the conductor be placed at the center of the
closed jaws for maximum accuracy.
3. When the reading is lower than 400 counts, set the range switch
to the next lower range position. For maximum accuracy, select
the lower range possible without over ranging the meter.
2.2 Voltage Measurements
1. Connect the red test lead to the “VV”jack and the black test lead
to the “COM” jack.
2. Set the Function/Range switch to the desiredVoltage type (AC or
DC) and range. If magnitude of voltage is not known, set switch
to the highest range and reduce until a satisfactory reading is
obtained.
3. Connect the test leads to the device or circuit being measured.
4. ForDC,a(-) signisdisplayedfornegativepolarity;positivepolarity
is implied.
2.3 Frequency Measurements
1. Set the Function/Range switch to the “Hz” position.
2. Connect the red test to the “VV” jack and the black test lead to
the “COM” jack.
3. Connect the test leads ro the point of measurements and read
the frequency from the display.
2.4 Temperature Measurements
WARNING : Remove test leads before measuring temperature
1. Set the Function/Range switch to the “0C” position.
2. Connect a k type thermocouple to the jack on the instrument.
Place the probe or thermocouple tip on or in the material to be
measured and take the temperature reading directly from the
display.
2.5 Diode Test
1. Connect the red test lead to the “VV” jack and black test lead 1o
the “COM” jack.
2. Set the Function/rRange switch to the diode position.
3. Turn off power to the circuit under test.
4. Touch probes to the diode. A forward-voltags drop is about 0.6V
(typical for a silicon diode.)
5. Reverse probes It the diode is good, display will be between
2.800V and 3.200V. If the diode is shorted, “.000” or another
number is displayed.
6. If the diode is open, display will be between 2.800V and 3.200V,
in both directions.
7. If the diode is measured in a circuit and a low reading is obtained
with both lead connections, the diode may be shunted by a
resistance of less than 1kV. In this case the diode must be
disconnected from the circuit for accurate tasting
2.6 Resistance and Continuity Measurements
1. Set the Function/Range switch to the desired resistance range
or continuity position.
2. Disconnect power from the equipment under test.
3. Connect the red test lead to the “VV” jack and the black test lead
to the “COM” jack.
4. Touch the probes to the test points. In ohms, the value indicated
in the display is the measured value of resistance. In continuity
test, the beeper sounds continuously if the resistance is less
than100V.
3. MAINTENANCE
WARNING
Remove test leads before changing battery or performing any
servicing.
Battery Replacement
Power is supplied by a 9 volt “transistor” battery EVEREADY TYPE
216 or Equivalent. The “(+ -)” appears on the LCD display when
replacement is needed To replace the battery, remove the screw
from the meter and lift off the battery cover Remove the battery
from battery contacts and replace cover.
4. SAFETY INFORMATION
The following safety information must be observed to ensure
maximum personal safety during the operation of this meter :
1. Do not use the meter if the meter or test leads lock damaged, or
if you suspect that the meter is not operating properly.
2. This clamp meter is designed to take current measurements on
circuit with a maximum voltage difference of 500VAC between
any conductor and ground potential. Using the instrument for
current measurements on circuit above this voltage may cause
electric shock, instrument damage or damage lo the equipment
under test.
3. Turn offpowerto thecircuitunder testbeforecutting, unsoldering,
orbreaking thecircuitSmall amountsof currentcan bedangerous.
4. Use caution when working above 60V DC or 30V AC rms. Such
voltages pose a shock hazard.
5. Whenusing the probes,keepyourfingersbehindthe fingerguards
on the probes.
6. Measuring voltage which exceeds the limits of the clamp meter
may damage the meter and expose the operator to a shock
hazard. Always recognize the meter voltage limits as stated on
the meter.

DATA HOLD BUTTON
Press Data Hold button to toggle in and out of Data Hold mode, In the
Data Hold mode, the “ HOLD ” annunciator is displayed.
2.2 Voltage Measurements
1. Connect the red test lead to the “VV” jack and the black test lead
to the “COM” jack.
2. Set the Function/Range switch to the desired Voltage type
(AC or DC)
3. Connect the test leads to the device or circuit being measured.
4. For DC, a (-) sign is displayed for negative polarity; positive
polarityis implied.
2.3 Resistance Measurements
1. Connect red test lead to the “VV” jack and black test lead
to the “COM” jack.
2. Setfunction / Range switch toV/ /position.
3. If the resistance being measured is connected to a circuit,
turn off power to the circuit being tested and discharge all
capacitors.
4. Connect test leads across the resistance being measured.
When measuring high resistance, be sure not to contact
adjacent points even if insulated because some insulators
have a relatively low insulation resistance, causing the measured
resistance to be lower than the actual resistance.
5. Read resistance value on digital display. If a high resistance
vaiue is shunted by a large value of capacitance allow display to
stabilize.
2.4 DiodeTest
1. Connect the red test lead to the “VV” jack and black test lead
to the “ COM ” jack.
2. Set the Function / Range switch to the V/ /position, select
“” by pressing select key.
3. Turn off power to the circuit under test.
4. Touch probes to the diode. A forward-voltage drop is about
0.6V(typicalfor a silicon diode).
5. If the digital display reads overrange “ OL ”, reverse the lead
connections. The placement of the test leads when the forward
reading is displayed indicates the orientation of the diode. The
red lead is positive and the black lead is negative. If overrange
“ OL ” is displayed with both lead connections, the junction is
open. If a low reading (less than 1000) is obtained with both
lead connections, the junction is shorted internally or (if
junction is measured in a circuit) the junction is shunted by a
resistance less than 1KV. In the letter case the junction must
be disconnected from the circuit in order to verify its operartion.
2.5 Continuity Measurement

2. Set the Function/Range switch to the “ ” position.
3. Turn off power to the circuit under test.
4. Touch probes to the diode. A forward-voltage drop is
about 0.6V (typical for a silicon diode).
5. Reverse probes.If the diode is goad, “OL” is displayed.
If the diode is shorted, “.000” or another number is
displayed.
6. If the diode is open, “OL”is displayed in both directions.
7. If the junction is measured in a circuit and a low reading
isobtainedwith both lead connections,thejunctionmay
be shunted by a resistance of less than 1kV. In this
case the diode must be disconnected from the circuit
for accurate testing,
MAINTENANCE
WARNING : Remove test leads before changing battery
or performing any servicing.
Battery Replacement
Power is supplied by a 9 volt “transistor” battery. (NEDA
1604, IEC 6F22). The “ ” appears on the LCD display
when replacement is needed. Ta replace the battery,
remove the two screws from the back of the meter and lift
off the battery cover. Remove the battery from battery
