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 or fuses.
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.

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 600 or 400A range. If the range of the
measured is not known, select the higher range first then move to the lower
range if necessary.
2. Select AC or DC with the AC/DC button. Press the zero button to zero the
meter in the DCA mode only.
3. Press the trigger to open jaw. Fully enclose one conductor to be measured.
4. 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 V terminal.
Set the function switch to the V position.
Select AC or DC with the AC/DC button.
Connect the test leads in parallel to the circuit under test.
Read the voltage measurement on the LCD display.
Resistance and Continuity 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. 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
5. For Resistance tests, read the resistance on the LCD display.
6. For Continuity tests, if the resistance is < 30, a tone will sound.

Capacitance Measurements
WARNING: To avoid electric shock, discharge the capacitor under test before measuring.
CAP Position.
Set the function switch to the •)))
Press the multifunction button to select the capacitance function.
Insert the black test lead banana plug into the negative (COM) jack and
the red test lead banana plug into the positive jack.
Touch the test probe tips across the part under test.
Read the capacitance in the display.
The display will indicate the proper decimal point and value.
Temperature Measurements
WARNING: To avoid electric shock, disconnect both test probes from any
source of voltage before making a temperature measurement.
Set the function switch to TEMP.
Insert the Temperature Probe into the negative (COM) and the positive
jacks, making sure to observe the correct polarity.
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).
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
Data Hold
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 DH display icon appears on the LCD. Press the data hold button again to return to
normal operation.
Peak Hold
To hold the highest reading on the LCD, press the peak hold button. The peak 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 peak hold button was pressed.
Press the peak hold button again to return to normal operation.

WARNING: To avoid electrical shock, disconnect the meter from any circuit, remove the test leads
from the input terminals and turn OFF the meter before opening the case. Do not operate with open
Cleaning and Storage
Periodically wipe the case with a damp cloth and mild detergent; do not use abrasives or solvents. If
the meter is not to be used for periods of longer than 60 days, remove the battery and store it
Battery Replacement
1. Remove the Phillips head screw that secures the battery door.
Open the battery compartment
Replace the 9V battery
Replace and secure the door.
Temperature Probe Replacement
The replacement bead wire probe with banana plug connectors is p/n TP873.
To use type k probes with a mini plug connector requires a mini-plug to banana plug converter.
