Yes. The DL950 Power Quality Analyzer is equipped with a large-capacity lithium polymer battery pack. On-site detection does not require an external power supply, making it suitable for use in distribution cabinets, temporary power points, and other locations without mains power access. The battery capacity can support continuous measurement for multiple hours. The specific battery life varies depending on screen brightness and measurement load.
If it is to be used for issuing formal test reports or acceptance, it is necessary to focus on whether the device complies with GB or IEC 61000-4-30 Class A standards to ensure that the fundamental voltage error and harmonic measurement accuracy meet the requirements. The DL950 has a voltage/current measurement error of ≤±0.1% and can be connected to current transformers or clamp current transformers, adapting to different on-site wiring methods. The harmonic analysis function supports monitoring the harmonic content of the power grid. For the specific harmonic order range, please refer to the equipment technical manual.
The instrument is equipped with a 7-inch TFT color screen, which can display various data curves, making it convenient for on-site personnel to observe the changing trends of parameters such as voltage, current, and power. For screen resolution and refresh rate parameters, please refer to the accompanying technical documents.
The DL950 features multi-functionality in one unit. It can measure basic parameters such as single-phase AC voltage, single-phase AC current, and single-phase active power, and also supports pumping unit balance rate testing (current method and power method). Measurement range reference: single-phase AC voltage 50-750V, single-phase AC current 0.5-600A. The specific measurement items and ranges are subject to the actual configuration.
