INTRODUCTION
| TesterMeter-ETCR1520 Ring Main Unit Wireless Phase Phase Tester is specially designed and manufactured for high voltage ring main unit phase verification. The instrument has a voice prompt function, and the operation is particularly simple, safe and fast. The instrument can check the phase in the extremely low voltage line, the check-phase voltage is 1V～600V, and the check-phase distance is 30 meters. The nuclear phase meter also has the functions of testing phase, frequency and phase sequence. The instrument is composed of host, detector, monitoring software, USB communication line, etc. The host adopts a 3.5-inch true color LCD screen, which can display phase, frequency, phase sequence and nuclear phase results on the same screen; vector diagram indication, phase indication, clear and intuitive; It has voice prompt functions such as "X signal is normal, Y signal is normal, in-phase, out-of-phase", which makes the test simpler and easier. The monitoring software has the functions of online real-time monitoring, historical data query, vector diagram indication, and phase indication; it has functions such as reading, viewing, saving, and printing historical data. |
Main Features
1. Using wireless transmission technology, the nuclear phase distance is 30 meters, and the nuclear phase is accurate and convenient to operate. 2. Voice prompt: "X signal is normal, Y signal is normal, in-phase, out-of-phase". 3. The 3.5-inch LCD color screen can display the phase, frequency, phase sequence, and nuclear phase results on the same screen, and the dynamic vector diagram indication is clear and intuitive. 4. Data storage function, can store 200 sets of data. USB interface data upload function, the stored data can be uploaded to the computer, saved and printed. |
