SAFETY NOTES
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.
WARNINGS
Set function switch to the appropriate position before measuring.
When measuring volts do not switch to current/resistance modes.
When changing ranges using the selector switch always disconnect the test leads from
the circuit under test.
Do not exceed the maximum rated input limits.
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.
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
NOTICES: Read and understand all warning and precaution statements listed in the
safety section of this operation manual prior to using this meter. Set the function
select switch to the OFF position when the meter is not in use.
AC/DC Current Measurements
WARNING: Ensure that the test leads are
disconnected from the meter before making current
clamp measurements.
1. Set the Function switch to
the 400ADC,40ADC,400AAC or40AAC range.
2. If the range of the measured is not known,
select the higher range first then move to the lower
range if necessary.
3. Press the trigger to open jaw. Fully enclose one conductor
to be measured.
The clamp meter LCD will display the reading.
AC/DC Voltage Measurements
1. Insert the black test lead into the negative COM terminal and the
red test lead into the positive Vterminal.
2. Set the function switch to the Vposition.
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 Measurements
1. Insert the black test lead into the negative COM terminal and the
red test lead into the positive terminal.
2. Set the function switch to the •))) CAP 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 tests, read the resistance on the LCD display.
Diode and Continuity Measurements
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 •))) CAP position.
3. Press the MODE button until “ “ appears in 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 “OL”. Shorted devices will indicate near 0mV and an open
device will indicate “OL” in both polarities.
For Continuity tests, if the resistance is < 150, a tone will sound.
Capacitance Measurements
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.Set 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 in the display
Frequency or % duty cycle measurements
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 Measurements
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 ℃℉.
2. Insert the Temperature Probe into the negative (COM) and the 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 in 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 ch
anging to another measurement function

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/CAP,
Data Hold Button
To freeze the LCD meter reading, press the data hold button. The data hold button is
located on the left side of the meter (top button). While data hold is active, the HOLD
display icon appears on the LCD. Press the data hold button again to return to normal
operation.
REL BUTTON
For DCA and Capacitance Zero & Offset adjustment.
RANGE BUTTON
When the meter is first turned on, it automatically goes into AutoRanging. This automatically selects the
best range for the measurements being made and is generally the best mode for most measurements.
For measurement situations requiring that a range be manually selected, perform the following:
1. Press the RANGE button. The “Auto Range” display indicator will turn off, The “Manual Range”
display indicator will turn on
2. Press the RANGE button to step through the available ranges until you select the range you want.
3. Press and hold the RANGE button for 2 seconds to
exit the ManualRanging mode and return to AutoRanging.
Battery Replacement
1. Remove the one rear Phillips head screw
2. Open the battery compartment
3. Replace the Requires One 9V battery
4. Re-assemble the meter
