As a dedicated manufacturer with over a decade of experience in electrical testing equipment, Jinhua Dika Electrical Equipment Co., Ltd. is proud to introduce the Auto Clamp Multimeter CM-3002. Engineered specifically for the demanding environments of HVAC servicing and industrial motor maintenance, this tool is designed to provide technicians with reliable, accurate, and safe current diagnostics. Our commitment to quality, evidenced by our adherence to international management standards like ISO 9001, ensures that the CM-3002 meets the rigorous expectations of professionals across North America, Europe, Southeast Asia, and our other key global markets. This clamp meter represents a fusion of practical functionality and robust construction, aimed at enhancing your diagnostic efficiency and workplace safety.
The CM-3002 is built to tackle the most common and critical measurements in field service and facility maintenance. Its core value lies in simplifying complex diagnostics, allowing users to quickly identify issues with motors, compressors, fans, and entire HVAC systems without breaking the circuit. Let's delve into its key features and specifications:
- Versatile Current Measurement: The auto-clamp jaw facilitates non-intrusive measurement of both AC and DC currents, which is crucial for diagnosing motor starting currents, running loads, and potential faults in HVAC systems.
- Comprehensive Electrical Testing: Beyond current, it functions as a full-featured digital multimeter, capable of measuring AC/DC voltage, resistance, continuity, diode test, and capacitance—a vital function for checking motor run/start capacitors.
- Enhanced Safety Design: Constructed with user protection in mind, the meter is designed to comply with safety standards for its category. The insulated clamp and test leads provide an added layer of security when working on live circuits.
- User-Centric Operation: Features like Data Hold, Peak Hold (to capture inrush currents), and an auto-ranging/manual-ranging toggle make it adaptable for both novice and experienced technicians. A backlit LCD display ensures readability in poorly lit mechanical rooms or outdoor installations.
- Durable and Portable: Housed in a drop-resistant casing with a integrated stand, it is built for daily use in toolboxes and service vans. The included carrying case offers further protection for all components.
Here is a summary of its primary technical specifications:
| Parameter | Specification / Range |
| AC Current | 0.1A to 600A (typical) |
| DC Current | 0.1A to 600A (typical) |
| AC/DC Voltage | 0.1V to 600V |
| Resistance | 0.1Ω to 40MΩ |
| Capacitance | 0.1nF to 10mF |
| Clamp Jaw Size | Maximum 30mm diameter |
| Display | Digital LCD, 3.5 to 4 digits |
| Power Supply | 9V Battery (included) |
| Operating Environment | Standard commercial/industrial temperature ranges |
The advantages of using the CM-3002 translate directly into benefits for your business:
- Increased Diagnostic Speed: The clamp-on design allows for instantaneous current readings without shutting down equipment, minimizing system downtime for clients.
- Improved Accuracy & Problem-Solving: Accurate measurements of current, voltage, and capacitance enable precise identification of issues like motor overload, phase imbalance, or failing capacitors, leading to correct repairs on the first visit.
- Enhanced Technician Safety: The built-in safety features help protect your team from electrical hazards, contributing to a safer work environment and reducing liability risks.
- Cost-Effective Tooling: Combining a clamp meter and a standard DMM into one reliable device reduces the need to purchase and carry multiple tools, optimizing your equipment investment.

Frequently Asked Questions (FAQ)
Q1: What is the main purpose of the CM-3002 clamp meter?
A1: The CM-3002 is specifically designed for HVAC technicians and industrial maintenance personnel. Its primary function is to safely and accurately measure AC and DC current in motors, compressors, and other electrical components without disconnecting wires, making it ideal for diagnostics and preventive maintenance.
Q2: Can it measure both AC and DC current?
A2: Yes, a key feature of this model is its ability to measure both alternating current (AC) and direct current (DC). This is particularly useful for diagnosing various types of motors and control circuits found in modern systems.
Q3: How large of a conductor can the clamp jaw accommodate?
A3: The clamp jaw is designed to open to a maximum diameter of approximately 30mm. This size is suitable for measuring current in single conductors commonly found in residential, commercial, and many industrial applications.
Q4: Does it have a feature to capture inrush current?
A4: Yes, the CM-3002 includes a Peak Hold function. This allows the meter to capture and display the momentary high inrush current when a motor or compressor starts, which is critical for assessing starting system health.
Q5: What safety standards does it meet?
A5: The meter is designed with safety as a priority and is typically rated for use on circuits up to a certain voltage category (e.g., CAT III 600V). For the exact certification marks and ratings applicable to this specific model, please contact us for the latest compliance documentation.
Q6: What is included in the standard package?
A6: The standard package typically includes the CM-3002 clamp meter, a set of test leads, a 9V battery, a user manual, and a protective carrying case for convenient storage and transport.
Q7: Is the display easy to read in dark areas?
A7: To aid visibility in poorly lit environments such as equipment rooms or panels, the digital LCD display is equipped with a backlight function. This feature can be activated as needed for clear reading of measurements.
Q8: Can this meter measure capacitance?
A8: Absolutely. The capacitance measurement function is a valuable addition for HVAC work, allowing technicians to test the health of motor run and start capacitors directly, which is a common point of failure in systems.
