This symbol, adjacent to another symbol or terminal, indicates the user must
refer to the manual for further information.
This symbol, adjacent to a terminal, indicates that, under normal use, hazardous
voltages may be present
Double insulation
•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.
•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.
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.

4.Operation
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.
Ensure that the test leads are disconnected from the meter before
making current clamp measurements.
Set the Function switch to the range.
If the range of the measured is not known, select the higher range first then move
to the lower range if necessary.
1.Press the trigger to open jaw. Fully enclose one conductor to be measured.
2.The clamp meter LCD will display the reading.

1.Insert the black test lead into the negative terminal and the red test lead into
the positive V terminal.
2.Set the function switch to the position.
3.Select AC or DC with the button.
4.Connect the test leads in parallel to the circuit under test.
5.Read the voltage measurement on the LCD display.
1.Insert the black test lead into the negative terminal and the red test lead into
the positive terminal.
2.Set the function switch to the position.
3.Use the multifunction button to select resistance.
4.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.
5.For Resistance tests, read the resistance on the LCD display.
6.For Continuity tests, if the resistance is < 120 , a tone will sound.
1.Insert the black test lead banana plug into the negative jack and the red test
lead banana plug into the positive diode jack.
2.Turn the rotary switch to the 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.

4-7.Battery Replacement
To hold the highest reading on the LCD, press the MAX hold button. The MAX hold
button is located on the left side of the meter (bottom button). The meter reading
will not change as readings change, rather it will only display the highest reading
encountered since the MAX hold button was pressed. Press the MAX hold button
again to return to normal operation.
The backlight function illuminates the display and is used when the ambient light
to too low to permit viewing of the displayed readings. Press the button for one
second to turn the backlight on and press the button a second time to turn the
backlight off.
1.Remove the one rear Phillips head screw
2.Open the battery compartment
3.Replace the Requires two “AAA” batteries (UM4 R03)
4.Re-assemble the meter
