Calibration

The GAS CHECK SF6 is unique in that completely separate values are stored for each of the display modes. This means that if you want to measure ppm or gm/yr these values must be calibrated before use. Calibration follows the same easy routine as with cc/sec calibration using the Portable Reference Leak. Regular calibration further improves the precision of measurement over the standard (factory set) calibration.

For cc/sec (volume loss over time mode) You will need the Portable Reference Leak (PRL), supplied as an option with the instrument and available from Ion Science Ltd.

The leak rate will be approximately 5x10-6cc/sec (5 E-6cc/sec)

Press Calibration. The screen now asks you to enter (or confirm) the leak rate of the PRL (or gas concentration when in ppm mode). If this is to be changed, then use the keypad to enter the SAME leak rate as printed on the PRL.

As long as the same PRL / gas concentration is used, this value needs to be entered only once. Just press RETURN to confirm it each time you make a calibration.

On pressing RETURN the calibration process begins.

Background Air is measured first, which takes 4 seconds. A time bar is displayed along with an audible ‘bleep’. The display then instructs the operator to put the probe to the reference leak. When this is done, the final calibration step begins automatically and takes 6 seconds.

During this time, it is important to hold the probe accurately in the reference leak, otherwise an incorrect calibration may occur.

Should the leak be missed or the probe removed by mistake, just move the probe off the leak. The time bar is then reset, and the process can be re started.

When calibration is complete, the instrument returns to normal mode. Now check the portable reference leak, which should be the same reading (+/-5%). Repeat the calibration if necessary, and remember to accurately hold the probe in the leak.

The Exit button can be used to abort calibration at any time. The original calibration factor then remains unchanged.

Set clock

The clock keeps time even while the instrument is off. Adjustment may be necessary for the following: Summer / winter time changeover, Different time zone

Normal long term adjustment.

If the battery has been disconnected. Should this happen, the instrument automatically opens the set date/time screen after power on.

This is quite straightforward; use the -/+ pads to change and when correct press Exit.

SF6 specifications

Innovation technology in the realm of electrical applications has increasingly turned its focus towards SF6, or sulfur hexafluoride. This gas is recognized for its excellent insulating properties and is widely utilized in high voltage equipment. SF6 is colorless, odorless, and non-toxic, making it a preferred choice for many industries, particularly in electrical utilities and power generation.

One of the main features of SF6 technology is its superior dielectric strength. The gas can prevent electrical discharges even in high voltage environments, which minimizes the risk of electrical failures and enhances the safety of electrical equipment. Furthermore, the thermal stability of SF6 allows it to withstand significant temperature variations, making it highly effective in various environmental conditions.

Another notable characteristic is its ability to quench electrical arcs. SF6 has a high electron affinity, meaning it can effectively absorb free electrons present during arcing, thereby extinguishing the discharge. This feature is crucial for circuit breakers and switchgear, ensuring reliable operation and protection against faults.

In addition to its insulating capabilities, SF6 technology supports a range of innovations in smart grid applications. The gas is compatible with advanced monitoring systems that facilitate real-time assessments of electrical equipment’s health and performance. These monitoring systems can detect potential issues before they escalate, promoting preventive maintenance and reducing downtime.

However, despite these advantages, the environmental impact of SF6 has raised concerns. As a potent greenhouse gas with a global warming potential significantly higher than CO2, industries are exploring alternatives and seeking ways to mitigate SF6 emissions. Innovations such as gas mixtures and the development of alternative insulating technologies are underway, aiming to address these challenges while maintaining reliability and efficiency.

Furthermore, ongoing research continues to improve the lifecycle management of SF6, encompassing better handling, recycling technologies, and effective disposal methods. Transitioning towards a circular economy in the use of SF6 presents an exciting frontier in electrical technology, marrying the benefits of reliable insulation with unwavering commitment to environmental stewardship.

In conclusion, innovation technology in SF6 embodies a blend of superior electrical performance and an urgent need for sustainable practices, marking a pivotal point in the evolution of electrical engineering and power management systems. As industries navigate the balance between performance and environmental responsibility, SF6 remains at the forefront of technological advancements in high voltage applications.
