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 1000ADC,600ADC,
1000AAC or600AAC 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
conductorto be measured.

The clamp meter LCD will display the reading.

DC/AC Voltage Measurements

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 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.

Ω

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.

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.et 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/duty cycle Measurements (electronic)

1.Set the rotary function switch to “V” position.

2.Select ACV with the MODE button

3.Press the Hz/% button to indicate “Hz” in the display.

4.Insert the black lead banana plug into the negative COM
jack and the red test lead banana plug into the positive Hz jack.

5.Touch the test probe tips to the circuit under test.

6.Read the frequency on the display.

7.Press the Hz/% button again to indicate “%” on the display.
Read the % of duty cycle on the display.

Ω

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 TEMP.

2.Insert the Temperature Probe into the negative (COM) and
the V jacks, making sure to observe the correct polarity.

3.Select °C o°F with the MODE button.

4.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).

5.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 changing to another measurement
function

Non-Contact AC Voltage Measurements

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.

MODE BUTTON

To select DC/ACV,OHM/ Diode/Continuity/CAP , °C/°F

MIN & MAX Recording Button

Press MIN/MAX to enter MIN, MAX Recording mode (manual
range only ). Select the proper range before selecting MIN
MAX to ensure that the MIN/MAX reading will not exceed the
testing range. Press once to select MIN. Press again to select

MAX. and press again release MIN/MAX recording function.

REL BUTTON

For DCA Zero & Offset adjustment.

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.
Note: The HOLD feature will activate when the Backlight is
turned on. Press the HOLD key again to exit Hold.

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.

Backlight Button

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 two seconds to
turn the backlight on and press the button a second time to
turn the backlight off.

Battery Replacement

1.Remove the one rear Phillips head screw

2.Open the battery compartment
