INTRODUC TION
SAFETY
This clamp meter is a hand-held digital Clamp Meter for automotive and
construction use, where high current measurement is required. The Clamp Meter
can measure the following:
• AC/DC Voltage
• AC Current
• Resistance
• Capacitance
• Frequency
• Continuity
• Diode
• Temperature
The Heavy Duty Open Jaw Clamp Meter features:
• Auto Power OFF
• Data Hold
• Backlight LCD display
2-1. International Safety Symbols
This symbol, adjacent to a terminal, indicates that, under normal use,
hazardous voltages may be present.
Double insulation
2-2. Safety Notes (see table in section 2-4).
• Do not exceed the maximum allowable input range of any function.
• Do not apply voltage to meter when resistance functions is selected.
• Set the function switch OFF when the meter is not in use.
• Remove the battery if meter is to be stored for longer than 60 days.
2-3. Warnings
• Set function switch to the appropriate position before measuring.
• When measuring voltage, do not switch to current/resistance modes.
• Do not measure current on a circuit whose voltage exceeds 600V.
• When changing ranges, always disconnect the test leads from the circuit
under test.
• Replace the batteries as soon as the low battery indicator appears.

SAFETY
2-4. 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 taking measurements if the voltages are greater than
25VAC rms or 35VDC. These voltages are considered a shock hazard.
• 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
6-6. Capacitance Measurements
To avoid electric shock, discharge the capacitor under test before measuring.
• Set the function switch to Ω CAP position.
• Insert the black test lead banana plug into the negative COM jack and the red
test lead banana plug into the V Hz% Ω TEMP positive jack.
• Use the MODE button to select CAP measurements.
• Touch the test probe tips across the part number under test.
• Read the capacitance value in the display.
• The display will indicate the proper decimal point and value.
Note: When set to this position, Data Hold and backlight function cannot be used.
For very large values of capacitance measurement, it can take several minutes
before the final reading stabilizes.
• Touch the test probe tips across the circuit or component under test.
• If the resistance is at less than 50Ω, a tone will sound.
6-7. Diode Measurements
• Insert the black test lead banana plug into the negative COM jack and the red
test lead banana plug into the V Hz% Ω CAP positive jack.
• Turn the function switch to Ω CAP position. Use the MODE button to
select the diode function if necessary (diode symbol will appear on the
LCD when in Diode test mode).
• Touch the test probe tips to the diode or semiconductor junction under test.
Note the meter reading.
• Reverse the test lead polarity by reversing the red and black leads. Note
this reading.
• The diode or junction can be evaluated as follows:
1. If one reading displays a value (typically 0.400V to 0.900V) and the other
reading displays “OL”, the diode is good.
2. If both readings display “OL” the device is open.
3. If both readings are very small or “0”, the device is shorted.
Note: When set to this position, Data Hold and backlight function cannot be used.

normal operation.
Automatic Power OFF
LCD Backlight Button
The LCD is equipped with backlighting for easier viewing, especially in dimly lit
areas. Press the HOLD button for over 1 second to turn the backlight on. Press
again for over 1 second to turn the backlight off.
To avoid electric 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 the meter with an open case.
• 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 60 days or more, remove
the battery and store it separately.
• Battery Replacement
1. Remove the Phillips head screw that secures the rear battery door.
2. Open the battery compartment.
3. Replace the 1.5V* 2 AAA batteries.
4. Replace battery door and Phillips head screw.
In order to conserve battery life, the meter will automatically turn off after
approximately 30 minutes. To turn the meter on again, turn the function switch to
the OFF position and then to the desired function position.
