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.

Auto Power-down mode

If unused for about 30 minutes, the tester will power-down automatically. If you
should diseble Auto Power-down mode, press SELECT buttom when you turn
on the meter.

SELECT Function Button (DC/AC),(

The SELECT Function button is Yellow in color. Press it to toggle to the
alternate function (AC, Audible continuity , and Diode ) shown in Yellow on the
meter face.

RANGE Button

Press (RANGE) button to select the Manual Range mode and turn off the
"AUTO" annunciator.
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 "AUTO" annunciator turns back on.

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 function.

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 current function(AC or DC). In DC

current measurement use

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.

DD

DZERO button, offset the residual magnetic of

DD

Resistance Measurements

1. Set the Function/Range switch to W/ 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. 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.

8

Diode Tests

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

2. Remove power from the equipment under test.

3. To toggle the W/continity/diode modes, press SELECT Switch.

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.

7. If the junction is measured in a circuit and a low reading is obtained with both

lead connections, the junction may be shunted by a resistance of less than

1kW. In this case the diode must be disconnected from the circuit for

accurate testing.

Continuity Measurements

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

2. Turn off power to the circuit under test. External voltage across the

components causes invalid readings.

3. To toggle between the W/continity/diode modes, press SELECT button.

4. Connect the test leads to the two points at which continuity is to be tested.

The buzzer will sound if the resistance is less than approximately 100W .

9

Frequency Measurements

1. Set the Function/Range switch to the Hz position, and then press Hz-% to

toggle between "Hz" and "DUTY" mode.

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.

Duty Cycle Measurements

1. Set the Function/Range switch to the Hz position, and then press Hz-% to

toggle between "Hz" and "DUTY" mode.

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 .The display will indicate

0.1% to 99.9% of the frequency duty cycle.

Capacitance Measurements

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

2. Dischange capacitors before trying to measure it.

3. Connect the " + " lead to the " + " jack and the " - " lead to the "COM" jack.

4. Read the capacitance directly from the display.

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.
