SAFETY NOTES
xDo not exceed the maximum allowable input range of any function
xDo not apply voltage to meter when resistance function is selected.
xSet the function switch OFF when the meter is not in use.
WARNINGS
xSet function switch to the appropriate position before measuring.
xWhen measuring volts do not switch to current/resistance modes.
xWhen changing ranges using the selector switch always disconnect the test leads from
the circuit under test.
xDo 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.
xVoltage 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".
xIf 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.

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.

voltage before making a temperature measurement.
1. Set the function switch to ć.
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
Non-Contact AC Voltage Measurements
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.
WARNING: Risk of Electrocution. Before use,
always test the Voltage Detector on a known live
circuit to
verify proper operation
