The Chauvin Arnoux CA 5293 is a portable graphic multimeter from the ASYC IV series, designed for use in laboratories and field applications. It combines high measurement accuracy with extensive functionality, enabling the analysis of electrical signals and documentation of measurement trends. The device is designed for direct measurement of voltage, current, resistance, frequency, and temperature, and features a TRMS display with a resolution of 100,000 points. Measurement ranges extend from 10 µV to 1000 V DC and 600 V AC, with DC accuracy at 0.02 %. The bandwidth for AC measurements is 200 kHz, making it suitable for analyzing high-frequency signals. Frequency measurement is possible over a range of 10 Hz to 5 MHz, with a base accuracy of 0.07 %. Resistance measurement covers ranges from 100 Ω to 100 MΩ, and capacitance measurement offers resolutions from 1 pF to 10 µF. Temperature measurement is possible using PT- and TK-sensors, with operating temperature ranges of -200 °C to 800 °C (PT) and -40 °C to +1200 °C (TK). Voltage measurement across diodes in open circuit conditions is performed with a maximum value of 26 V at 10 mA. Acoustic continuity testing is possible for resistances below 20 Ω.

Applications
This multimeter is suitable for various applications in electrical engineering, electronics, machine and plant construction, and industry. It is used for maintenance of industrial machines, numerical controls, motors, and generators. In telecommunications and energy supply, it is used for testing wiring, IT and medical devices, and for measurements on heating and air conditioning systems. The IP67 protection rating makes it suitable for outdoor use, as it is dust- and waterproof. The robust construction and safety measurement sockets compliant with IEC61010-1 with 1000 V CAT III and 600 V CAT IV ensure safe operation even in demanding environments.

Functions and Equipment in Detail
The device features a color graphic display with a resolution of 320 x 240 pixels and a black background, capable of displaying up to four measurement values simultaneously. The graphical representation allows for the display of trend curves over a variable time base from 1 minute 28 seconds to 1 hour 13 minutes 20 seconds. Waveform display is possible up to 600 Hz in automatic mode. The data logger function stores up to 30,000 measurement values and allows setting of measurement intervals, recording duration, and storage capacity. MIN/MAX/AVG/PEAK values are displayed with timestamps, facilitating signal trend monitoring. The REL function enables relative measurements, and the MLI filter function (low-pass 300 Hz, 4th order) is intended for measurements on asynchronous motor variable speed drives. The SPEC function displays measurement accuracy as well as Smin and Smax. Secondary measurements include up to three additional measurement values alongside the primary measurement.

Technology Explained Simply
The TRMS measurement (True Root Mean Square) enables accurate measurement of AC voltage and current, even with non-sinusoidal signals. The resolution of 100,000 points ensures high accuracy in displaying measurement values. The measurement rate of 5 measurements per second ensures timely representation of signal trends. The optical USB interface enables data transfer to a PC, where the SX-DMM software can be used for analysis and documentation of measurement data. The Bluetooth interface (optional) extends connectivity. Power supply is via 4 AA batteries or rechargeable Ni-MH batteries, and the device can also be operated during charging. Charging is done via USB 5 V, enabling flexible power supply. The battery life is up to 100 hours.

Compatibility and Accessories
The multimeter is compatible with various accessories, including a set of 4 Ni-MH batteries, fast charging set (fast charger + 4 NiMH AA batteries), optical USB cable, thermocouple adapter and Type K temperature sensor, and various current clamps such as clamp for SMD components, MINI 02 - 1000/1 clamp, MN08 DA 200/0,2 clamp, MN71 CV 10/1 clamp, MN73 CV 2-200/2 clamp, MN09 CA 200/0,2 clamp, MN89 CV 200/20DC clamp, C107 CV 1000/1 clamp, C106 DV 1000/1 clamp, MiniFlex MA110 3-30-300-3000A/3V (170 mm and 250 mm), AmpFlex A110 3-30-300-3000A/3V (045 cm), PAC16 CVH clamp, and PAC26 CVH clamp.
