Chauvin Arnoux P01196775 CA 5275 digital multimeter content_copy

The Chauvin Arnoux CA 5275 is a digital multimeter with TRMS measurement function for alternating and direct voltage as well as alternating and direct current. It is designed for electrical maintenance of installations and machines and features a compact, shock-protected housing with a foldable stand bracket. The device offers a dual, backlit display with 6000 points each and a bar graph indicator with 63 bi-modal elements, operating in two modes (full scale / central zero) and featuring a glow effect. This display enables quick and precise reading even in poorly lit environments.

Applications
This multimeter is suitable for various applications in the field of electrical maintenance, particularly in industry and machine servicing. Notably, it includes a function for measuring ionization currents, making it suitable for testing flame detectors. The high measurement ranges and high resolution of 10 µV and 1 µA allow precise measurements even at very low signal levels.

Functions and Equipment in Detail
The device measures voltages up to 1000 V (AC, DC, AC+DC) and currents up to 10 A (AC, DC, AC+DC), with the current range being overloadable to 20 A for 30 seconds. Resistance measurement extends up to 60 MΩ, capacitance measurement up to 60 mF, and frequency measurement covers a range from 600.0 Hz to 20.00 kHz. Additional functions include an audible continuity test, diode test, display hold (HOLD), and Min/Max measurement with a response time of 100 ms. The measurement rate is 5 readings per second.

Technology Explained Simply
TRMS measurement (True Root Mean Square) enables accurate capture of alternating quantities, even with distorted or disturbed signals, as it measures the actual RMS value. The VLowZ function (low impedance) with integrated low-pass filter ensures precise measurement at low voltages and reduces interference from parasitic capacitances. The dual display with 6000 points and the bar graph indicator support quick visual orientation. The resolution of 10 µV and 1 µA enables measurement of very small voltages and currents, which is important for specific applications such as ionization current testing.

Compatibility and Accessories
The multimeter is equipped with safety class CAT IV 600 V / CAT III 1000 V and protection rating IP54, making it suitable for use in industrial environments. Compatible accessories include test leads with 4 mm plugs (straight/angled), test probes, crocodile clips, a carrying case, and high-performance fuses. These components can be purchased separately to enhance functionality and safety during measurements.

Mounting and Installation
The device is connected directly to the conductors to be measured. The test leads are fitted with 4 mm plugs that are inserted into the corresponding sockets on the multimeter. Operation is performed via a rotary knob for selecting measurement functions and ranges. Power supply is via a 9V battery (type 6LR61), which is included in the delivery scope.

Operational Advantages
The combination of TRMS measurement, high resolution, dual display, and additional functions such as Min/Max and HOLD provides comprehensive support for diagnosing electrical systems. The safety class CAT IV 600 V / CAT III 1000 V and protection rating IP54 ensure safe operation in demanding environments. The ionization current measurement function extends the application range in specific uses such as burner monitoring.

The device was developed and manufactured in France by Chauvin Arnoux and comes with a 3-year warranty. The delivery scope includes the multimeter, test leads, batteries, and the operating manual.
