Wireless Phase Frequency Sequence Meter

Q:  What is the main advantage of a wireless measuring device over a conventional device?

A:Safety and convenience. Thanks to the wireless design, you can attach the compact transmitters to live connections and read the results from a safe distance away from the control cabinet. This eliminates the danger posed by long measuring cables, which can be accidentally pulled or fall onto other components.

Q: How does the wireless connection function?

A:The system typically employs low-power robust radio protocols (such as 2.4 GHz). The transmitter's measurement clamp captures voltage waveforms and transmits this data digitally to a central receiving unit, which calculates the phase angle, frequency, and sequence.

Q: What is the typical wireless transmission range?

A:Most models offer a reliable transmission range of 20 to 50 metres (65 to 165 feet) in open spaces. Walls, metal cabinets and other obstacles reduce the transmission distance. Please refer to the manufacturer's specifications.

Q:Do I need to synchronise the transmitter with the receiver?

A:Yes, though this is typically an automatic process. You will usually need to switch on the receiver first, followed by the transmitter. They will connect automatically within a few seconds. For specific steps, please refer to the instruction manual.

Q: Can I use it in a single-phase system?

A:Yes. You may employ it in single-phase circuits to measure voltage and frequency. Certain advanced models can also determine the phase angle between voltage and current, facilitating power factor analysis for single-phase loads.
