The Multimeter / TRMS Multimeter enables detailed testing of USB chargers, USB-C cables and mobile devices. It records voltage, current and power, as well as the transferred capacity and energy. With measuring ranges of 4 ... 50V, 0 ... 6.5 A and up to 240 W, the device is also suitable for high-power USB-C charging systems. The integrated 20-bit A/D converter enables high-resolution display of the measured values.
For analysing modern charging methods, the Multimeter / TRMS Multimeter supports USB Power Delivery, including PD 3.1 EPR, as well as the detection of numerous other fast-charging protocols. Supported protocols can be triggered selectively to investigate charger behaviour. The E-marker readout provides information about suitably equipped USB-C cables. In addition, cable simulation and monitoring of PD communication enable more detailed investigation of potential compatibility issues.
To assess the power supply, the Multimeter / TRMS Multimeter provides waveform display and ripple measurement with sampling rates of up to 2 MS/s. Voltage and current curves can be recorded for up to nine hours. Ten statistics groups support the evaluation of capacity, energy and time. The 1.54-inch TFT colour display with 240 × 240 pixels and automatic orientation in four directions makes readings easier in different installation positions. A separate USB-C interface enables connection to a PC.
The Multimeter / TRMS Multimeter is suitable for development, quality assurance and servicing in the field of USB power supply. Typical applications include checking power supplies and power banks, assessing USB-C cables, and troubleshooting slow or interrupted charging processes. The device also supports the comparison of different combinations of charger, cable and load in electronics workshops and test laboratories.
