CAUTION
Improper use of this meter can cause damage, shock, injury or death. Read and
understand this user’s manual before operating the meter.
Always remove the test leads before replacing the battery.
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.
Remove the battery if the meter is to be stored for long periods.
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.

Operation
Note: Read and understand all warning and precaution statements listed in the safety section of
this instruction manual prior to using the meter. Set the function select switch to the OFF
position when the meter is not in use.
AC Current Measurement
WARNING : Ensure that the test leads are disconnected from the meter before making current
clamp measurements.
1. Set the function switch to 400 or 40A range.
2. If the range of the measured current is not known, select the higher range first than move
to the lower range, if necessary.
3. Press the trigger to open the jaw. Fully enclose one conductor to be measured.
4. Read the current measurement value on LCD display.
AC/DC Voltage Measurement
1. Insert the black test lead into the negative (COM) terminal and the red test lead into the
positive (V) terminal.
2. Set the function switch to the "V" position.
3. Select AC or DC with the MODE button.
4. Connect the test leads in parallel to the circuit under test.
5. Read the voltage measurement on the LCD display.

Resistance Measurement
1. Insert the black test lead into the negative (COM) terminal and the red test lead into the
positive (V) terminal.
2. Set the function switch to the "Ω"position.
3. Touch the test probe tips across the circuit or component under test. It is best to
disconnect one side of the device under test so the rest of the circuit will not interfere with
the resistance reading.
4. For resistance test, read the resistance on the LCD display.
Diode and Continuity Test
1. Insert the black test lead banana plug into the negative (COM) jack and the red test lead
banana plug into the positive diode jack.
2. Turn the rotary switch to the "Ω" position.
3. Press the ʺMODEʺ button until symbol appears on the display.
4. Touch the test probes to the diode under test. Forward voltage will indicate 0.4V to 0.7V.
Reverse voltage will indicate ʺOLʺ. Shorted devices will indicate near 0 mV and an
open device will indicate ʺOLʺ in both polarities.
For continuity test: if the resistance is <150, a tone will sound.

Capacitance Measurement
WARNING: To avoid electric shock, disconnect power to the unit under test and discharge all
capacitors before taking any capacitance measurements. Remove the batteries and unplug the
line cords.
1. Switch the rotary function switch to the "CAP"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. Touch the test leads to the capacitor to be tested.
4. Read the capacitance value on the display.
Frequency or % Duty Cycle Measurement
1. Set the rotary function switch to the "VDC/AC, Hz" position.
2. Insert the black lead banana plug into the negative (COM) jack and the red test lead
banana plug into the positive (V) jack.
3. Select "Hz or % Duty" with the Hz/% button.
4. Touch the test probe tips to the circuit under test.
5. Read the frequency on the display.
Temperature Measurement
WARNING: To avoid electric shock, disconnect both test probes from any source of voltage
before making a temperature measurement.
1. Set the function switch to °C or °F position.
2. Insert the temperature probe into the negative (COM) and the positive (V) jacks, making sure to
observe the correct polarity.
3. Touch the temperature probe head to the part whose temperature you wish to measure.
Keep the probe touching the part under test until the reading stabilizes (about 30 seconds)
4. Read the temperature on the display. The digital reading will indicate the proper decimal
point and value
WARNING: To avoid electric shock, be sure the thermocouple has been removed before
changing to another measurement function.

Non-Contact AC Voltage Measurement
WARNING: Risk of electrocution. Before use, always test the voltage detector on a known live
circuit to verify proper operation.
1. Touch the probe tip to the hot conductor or insert into the hot side of the electrical outlet.
2. If AC voltage is present, the detector light will illuminate.
Note
The conductors in electrical cord sets are often twisted. For best results, rub the probe tip along a
length of the cord to assure placing the tip in close proximity 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.
MODE Button
To select DC/ACV, Ohm/Diode/Continuity functions.
DATA HOLD Button
To freeze the LCD meter reading, press the ʺData Holdʺbutton. The ʺData Holdʺbutton is
located in the center of the rotary function switch. While data hold is active, the ʺHOLDʺ
display icon appears on the LCD. Press the ʺData Holdʺbutton again to return to normal
operation.
REL Button
For Capacitance Zero and Offset adjustment.
Hz% Duty Button
Press on the "Hz% Duty" button to choose frequency or duty cycle in the range of frequency.
Press ʺHz% Dutyʺbutton to measure frequency or duty cycle while measuring voltage. Press
on ʺHz% Dutyʺbutton to return to measurement of voltage.
Battery Replacement
1. Remove the one rear Phillips head screw.
2. Open the battery compartment.
3. Replace the required two ʺAAAʺ1.5V batteries (UM4 R03)
4. Re-assemble the meter.
