Frequently Asked Questions
What gas types can this instrument calibrate?
The instrument supports calibration of pure SF₆, SF₆/N₂ mixed gas, and SF₆/CF₄ mixed gas, making it compatible with a wide range of gas-insulated switchgear density monitoring systems.
Does the instrument require disassembly of the density monitor during calibration?
No. The instrument comes with a complete set of transition adapters that allow most models of switch density monitors to be calibrated directly on-site without disassembly, saving significant time and effort.
What output voltage options are available?
The instrument supports both 24VDC and 110VDC output voltage options. It also includes a contact resistance measurement function for comprehensive testing capability.
How is the calibration data stored and exported?
The instrument is equipped with a large-capacity internal memory for long-term storage of calibration records. Data can be conveniently exported via the built-in USB interface, which also supports system firmware upgrades.
What calibration pressure methods does the instrument support?
The instrument supports both zero pressure and working pressure calibration methods, providing flexibility to meet different field calibration requirements and standards.
Can the instrument print calibration results on-site?
Yes. The instrument is equipped with a high-speed micro thermal printer that can automatically print calibration results immediately after the calibration process is completed, providing instant documentation in the field.
