The instrument utilizes all-digital technology and is fully automated with intelligent measurement capabilities, featuring a large screen."5.7No Chinese content provided.TFTPure Color LCD Touch Screen Monitor, featuring full Chinese menu, test results can be automatically saved and printed, and operators can master it proficiently without professional training.

Key Features and Characteristics

（1Oil cup adopts national standards.GB/T5654-2007Three-electrode structure, inter-electrode spacing2mmEliminates the impact of stray capacitance and leakage on dielectric loss test results.

（2The instrument utilizes medium-frequency induction heating.PIDTemperature control algorithm. This heating method boasts non-contact between the oil cup and heater, even heating, fast speed, and convenient control, ensuring that the temperature is strictly maintained within the preset temperature error range.

（3(Internal Standard Capacitors)SF6 The inflatable three-point capacitive sensor maintains its dielectric loss and capacitance unaffected by environmental factors such as temperature and humidity, ensuring the instrument's accuracy remains consistent over extended use.

（4Enhanced Protection Features. In the event of overvoltage, overcurrent, or high-voltage short circuits, the instrument quickly shuts off the high voltage and emits a warning message. Additionally, a warning is issued if the temperature sensor fails or is not connected.

In the medium-frequency induction heating furnace, a temperature-limiting relay is installed. When the temperature exceeds...120At this point, the relay releases, and the heating stops.

（5Easier parameter settings for testing. Temperature setting range40～120℃; AC voltage setting range

200～2200VDirect Current Voltage Setting Range0～500V。

（6Adopting large screensTFTPure Color LCD Touch Screen Monitor, offering clear display. With simple setup, the instrument automatically conducts tests and stores, as well as prints test results.

（7Features a real-time clock; test dates and times can be saved, displayed, and printed with the test results.

（8The Empty Electrode Cup Calibration Function. Measures the capacitance and dielectric loss factor of the empty electrode cup to assess its cleaning and assembly condition. Calibration data is automatically saved for ease of relative dielectric constant and DC resistivity measurements.No Chinese content provided, please provide the news content to be translated..Certainly.Calculate.
