Turn instrument off and disconnect test leads. Clean the instrument by using
a damp cloth. Do not use abrasive cleaners or solvents.

Remove the batteries when instrument is not in use for a prolonged period of
time. Do not expose to high temperatures or humidity. After a period of storage
in extreme conditions exceeding the limits mentioned in the Specifications
section, allow the instrument to return to normal operating conditions before
using it.

Instruction Manual

GENERAL SPECIFICATIONS

The Klein Tools CL1000 is an auto-ranging clamp meter. It measures
AC / DC voltage, AC / DC current, resistance, capacitance, frequency, and
duty cycle. It can also test non-contact voltage, diodes, and continuity.

• Operating Altitude: 2000 meters

• Humidity: 80% max

• Operating Temperature: 0°C / 32°F to 45°C / 113°F

• Storage Temperature: 0°C / 32°F to 60°C / 140°F

• Accuracy Temperature: 18°C / 64°F to 28°C / 82°F

• Temperature Coef cient: 0.1*(specified accuracy) / °C

• Dimensions: 8.875" x 3.375" x 1.5" (225 mm x 86 mm x 38 mm)

• Weight: 11 oz. (303 g)

• Calibration: Accurate for one year

• Safety Rating: CAT III 600V

• Accuracy: ± (% of reading + # of least significant digits)

WARNINGS

To ensure safe operation and service of the tester, follow these instructions.
Failure to observe these warnings can result in severe injury or death.

• Before each use, verify meter operation by measuring
a known voltage or current.

• Never use the meter on a circuit with voltages that exceed the
category based rating of this meter.

• Do not use the meter during electrical storms, or in wet weather.

• Do not use the meter or test leads if they appear to be damaged.

• Ensure meter leads are fully seated, and keep fingers away from
the metal probe contacts when making measurements.

• Do not open the meter to replace batteries while the probes
are connected.

• Use caution when working with voltages above 60V DC,
or 25V AC RMS. Such voltages pose a shock hazard.

• To avoid false readings that can lead to electrical shock,
replace batteries if a low battery indicator appears.

• Unless measuring voltage or current, shut off and lock out
power before measuring resistance or capacitance.

• Always adhere to local and national safety codes. Use individual
protective equipment to prevent shock and arc blast injury where
hazardous live conductors are exposed.

E. Hold / Backlight / Worklight

• Press to hold the current input on the display.

• Press again to return to live reading.

• Press for 2 seconds to enable / disable lights.

• Using lights drains the battery significantly.

F. Auto / Manual Range

• Press repeatedly to cycle through manual ranges.

• Press for 2 seconds to return to auto ranging mode.

•

AT is displayed on LCD only during auto ranging mode.

G. Max / Min Hold

• Press to enter Max / Min mode; the largest and smallest values
will be saved while in this mode.

• Press repeatedly to alternate between the maximum and minimum readings.

• Press for 2 seconds to return to live reading and clear the stored
maximum and minimum values.

H. I. Battery Replacement

• When indicator is displayed on the LCD, batteries must be replaced.

• Remove the back screw and replace 2 x AAA batteries.

Do not attempt to measure more than

J. Magnetic Back

• Attach instrument to metal for hands-free use.

K. Bar Graph

• The bar graph shows an approximate analog representation
of a measurement.

• The bar graph responds much faster than the digital display.

• The scale of the bar graph is zero to the maximum reading of
the selected range.
