The KLEIN TOOLS CL900 Digital Clamp Meter is designed for electricians and technicians who need a rugged, versatile tool for demanding jobsite conditions. Its primary benefit is accurate AC/DC current and voltage measurement up to high levels, along with specialized functions like Inrush Current and Low Impedance modes, though its advanced features may require a learning curve for new users. This auto-ranging, TRMS meter offers a comprehensive suite of electrical testing capabilities in a durable, drop-resistant package with a backlit display for low-light visibility.

TRMS (True Root Mean Square) meters provide accurate readings for both linear and non-linear signals, including those with harmonics, which are common in modern electronic equipment and variable frequency drives. Average-sensing meters only provide accurate readings for pure sine waves.
Select the LoZ mode on the dial. Connect the black test lead to the COM terminal and the red test lead to the V terminal. Touch the probe tips to the circuit points you want to test. LoZ mode applies a low impedance to the circuit, reducing the possibility of false readings from induced voltages.
Inrush Current testing is used to measure the momentary high current that occurs when a motor or other inductive load is first powered on. This is crucial for sizing protective devices and diagnosing motor starting problems.
Yes, the KLEIN TOOLS CL900 can measure both AC and DC current directly through the clamp jaws, up to 2000A.
The meter is safety rated CAT IV 600V and CAT III 1000V, indicating its suitability for use in various electrical environments with appropriate precautions.
Battery life varies with usage, especially with the backlit display and specialized functions active. The auto power-off feature helps conserve battery life.
Yes, the KLEIN TOOLS CL900 typically includes a set of test leads, batteries, and a carrying case.
Ensure batteries are correctly installed and charged. Check battery contacts for corrosion and clean if necessary. Replace batteries if depleted.
Verify that the correct function and range are selected. Ensure test leads are securely connected. For clamp measurements, ensure the jaws are fully closed and clear of obstructions. Check if the circuit is within the meter's safety ratings (CAT IV 600V, CAT III 1000V).
Ensure the meter is in the correct mode for non-contact voltage detection. Verify that the target conductor is live. The sensitivity may be limited by distance or shielding; ensure proper proximity.
This indicates an 'over limit' condition, meaning the measured value exceeds the selected range or the meter's maximum capability. Select a higher range or ensure the measurement is within the meter's specifications.
Setup: Before first use, install the included batteries, ensuring correct polarity. Connect the test leads to the appropriate input jacks for voltage, resistance, and continuity testing. Select the desired measurement function using the rotary dial.
Compatibility: The CL900 is designed for general electrical testing and is compatible with standard electrical systems within its specified voltage and current ratings. Ensure the circuit being tested adheres to the meter's safety ratings (CAT IV 600V, CAT III 1000V).
Care: Keep the meter clean and dry. Clean the exterior with a soft, damp cloth; do not use abrasives. Inspect test leads and the clamp jaws regularly for damage. Store the meter in its included carrying case to protect it from dust and impact when not in use. Replace batteries when the low battery indicator appears. Note the auto power-off feature, which activates after 30 minutes of inactivity to conserve battery life; press any button or rotate the dial to reset.
