GENERAL SPECIFICATIONS

The Klein Tools CL2100 is a True RMS, auto-ranging clamp meter. It measures AC / DC voltage, AC / DC current, resistance, capacitance, frequency, duty cycle, and temperature. 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"

• Weight: 10.7oz.

• Calibration: Accurate for one year

• CAT 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.

• Device will power off after 30 minutes non-use.

• Turn the dial or press a button to wake.

• Disabled during Max / Min function.

• Holding Select button while turning on disables Auto Power-Off.

D. Select Functionality Button

• Switch between AC and DC.

• Switch between

and .

• Switch between ˚F and ˚C.

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.

• 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.

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.

L. Temperature Input Jack

• Input jack for K-type thermocouple probe.

M. Temperature Switch

• Move the switch down to measure temperature, and up to measure all other functions that require standard test leads. Test leads must be removed before using the temperature function.

N. Temperature Adjustment

• Remove batter y cover.

• Place temperature probe in distilled water with stirred crushed ice (a standard for 0°C and 32°F).

• Use a fine tip screwdriver to adjust the screw recessed in the bottom right corner of the battery cavity as shown until the display reads 32°F.

O. Relative Reading / Zero mode

• Press for 2 seconds to enable/disable mode and store reading.

• Display will show the difference between the stored reading and the live measurement.

FUNCTION INSTRUCTIONS

• Select AC or DC current source.

• Current above 2000µA will damage instrument.

Diode / Continuity Features: Continued on Reverse

• Select AC or DC voltage source.

4. Frequency (Hz) / Duty Cycle (See Feature Details) Features:

HOLD

• Select , ,or setting.

• Frequencies greater than 500 kHz will display “0.000Hz”.

5. Capacitance: < 4000µF Features:

HOLD

•

Safely discharge capacitor before measurement.

• Reading may take up to 60 seconds for large capacitors.

6. Resistance: < 40M

Features:

MAX/MINRANGEHOLD

• Do not measure resistance on a live circuit.

MAX/MINRANGEHOLD

• Center wire in guides for best accuracy.

• Opposing currents cancel (use line-splitter when necessar y).
