GENERAL SPECIFICATIONS

Klein Tools CL900 is an auto-ranging, true root mean square (TRMS)
digital clamp meter that measures AC/DC current via the clamp and
measures AC/DC voltage, resistance, continuity, frequency, duty­cycle, capacitance, and tests diodes via test-leads. It features a Low
Impedance (LoZ) mode for identifying and eliminating ghost or stray
voltages, and has a dedicated mode for capturing Inrush Current.

WARNINGS

To ensure safe operation and service of the meter, 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.

• Use only with CAT III or CAT IV rated test leads.

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

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

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

• Do not attempt to measure resistance or continuity on a live circuit.

• Do not hold meter above hand & finger guard during use.

WARNINGS

• Always adhere to local and national safety codes. Use personal

protective equipment to prevent shock and arc blast injury where
hazardous live conductors are exposed.

• Usage of this meter in any way other than that specified by the

manufacturer can impair safe operation, resulting in severe injury or death.

• To avoid risk of electric shock, disconnect leads from any voltage source

before removing battery door.

• To avoid risk of electric shock, do not operate meter while battery door is

removed.
