SAFETY INFORMATION

The following safety information must be observed to insure maximum

personal safety during the operation at this meter:

1. Do not use the meter if the meter or test leads look damaged, or if you
suspect that the meter is not operating properly.

2. Use caution when working above 60V dc or 30V ac rms. Such voltages pose
a shock hazard.

3. When Using the probes, keep your fingers behind the finger guards on the
probes.

4. Measuring voltage which exceeds the limits of the clampmeter 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.

5. If the equipment is used in a manner not specified by the manufacturer, the
protection provided the equipment may be impaired.

OPERATION

Before taking any measurements, read the Safety Information Section.

Always examine the instrument for damage, contamination (excessive dirt,
grease, etc.) and defects. Examine the test leads for cracked or frayed
insulation. If any abnormal conditions exist do not attempt to make any
measurements.

H Button

In voltage, current, frequency and doide functions, Press " H " button to toggle
in and out of the Auto Hold mode, the " H " annunicator is displayed. In Auto
hold mode, the meter will capture and hold the first stable non-zero(>100
digits) reading after a zero reading(<100 digits). Several consecutive mea­surements can be held and displayed without pressing the (A-H) buttion.
Simply by shorting the test leads together between measurements. In resis­tance, continuity and temperature functions, press " H " button to toggle in and
out of the Data Hold mode, the " H " annunicator is displayed.

PEAK HOLD Button: (only AC functions 40-60Hz)

Press "PEAK" button to toggle in and out of PEAK Hold mode. In the PEAK
Hold mode, the "MAX P " annunciator is displayed. [Accuracy: ±(10% rdg +
10dgts), effect reading: 800~4300]

MIN / MAX button

Press (MAX/MIN) to enter the MAX MIN AVG Recording mode (manual range
only). The RECORD annunciator turns on and the automatic power-off feature
is disabled.
Push (MAX/MIN) to cycle through the maximum(MAX), minimum(MIN),
average(AVG) and present readings. (AVG) is average last ten times reading
can be displayed. Press and hold down the (MAX/MIN) for 2 seconds to exit
and erase recorded reading.

DZERO Button

In voltage, current, frequency and doide functions, Press (

DD

DD

DZERO) button to

toggle in and out of the Relative mode, the "ZERO" annunciator turn on, zero
the display, and store the displayed reading as a reference value.

RANGE Button

Press (RANGE) button to select the Manual Range mode and turn on the "
" annunciator. (The meter selected next range it was in when manual ranging
was selected).
In the Manual Range mode. each time you press (RANGE) button, the range
(and the input range annunciator) increments, and a new value is displayed.
To exit the Manual Range mode and return to autoranging, press and hold
down (RANGE) button for 2 seconds. The "

" annunciator will disappear.

Voltage Measurements

1. Connect the red test lead to the "V" jack and the black test lead to the "COM"
jack.

2. Set the Function/Range switch to the desired voltage range (AC or DC). The
meter will automatically select the best voltage range.

3. Connect the test leads to the device or circuit being measured.

4. For dc, a (-) sign is displayed for negative polarity; positive polarity is implied.

Current Measurements

1. Set the Function/Range switch to the desired highest 700A range (AC or
DC). In DC current measurement use

DD

DD

DZERO button, offset the residual

magnetic of the jaws.

2. Press the trigger to open transformer jaws and clamp onto one conductor
only. Read the current directly on the display. It is recommended that the
conductor be placed at the center of the closed jaws for maximum accuracy.

3. When the reading is lower than 430 counts, set the range switch to the next
lower range position. For maximum accuracy, select the lower range
possible without overranging the meter.

Resistance Measurements

1. Set the Function/Range switch to the resistance range.

2. Remove power from the equipment under test.

3. Connect the red test lead to the " + " 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.

WARNING

The accuracy of the functions might be slightly affected, when exposed to
a radiated electromagnetic field environment, eg, radio, telephone or
similar.

Continuity Measurements

1. Set the Function/Range switch to the " " position.

2. Remove power from the equipment under test.

3. Connect the red test lead to the " + " jack and the black test lead to the "COM"
jack.

4. Touch the probes to the test points. the beeper sounds continuously, if the
resistance is less than 50W ±30W .

Diode Tests

1. Connect the red test lead to the " + " jack and the black test lead to the "COM"
jack.

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 good, "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.

10

Frequency Measurements

1. Set the Function/Range switch to the Hz desired range.

2. Connect the red test lead to the " + " jack and the black test lead to the "COM"
jack.

3. Connect the test leads to the point of measurement and read the frequency
from the display.

Temperature Measurements

1. Set the Function/Range switch to the "°C" position.

2. Connect the temperature transition adaptor to the meter and make sure "
+ " and " - " polarity is right position.

3. Connect a type k thermocouple to the jack on the transition adaptor. Place
the probe or thermocouple tip on or in the material to be measured and take
the temperature reading directly from the display.

WARNING

Remove test leads being measured

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. To replace the
battery, remove the two screws from the back of the meter and lift off the
battery cover. Remove the battery from battery contacts.

Cleaning

Periodically wipe the case with a damp cloth and detergent, do not use
abrasives or solvents.
