GA11 Analytic instrument Operating instructions

PublishTime：2021-10-09

●Data processing and data storage The analytic instrument model GA11 is a multi-sensor system for examining the quality of N2 / CleanAir / DryAir, e.g. in switchgear. The basic instrument consists of a built-in computer with touchscreen for processing and storage of up to 500 data records. The data records can be exported via the integrated USB interface.Extendable sensor system The sensor system of GA11 is module-based and can be extended. In addition, there is the possibility of storing measuring gas internally as well as pumping it back into the original gas compartment without losses after the measurement.Automatic adjustment of the gas quality After the measurement, the results will be compared with customer-specifically adjustable limit values according to e.g. CIGRE B3.02.01 or IEC 60480 standards. The operator thus obtains a reliable statement on whether the insulating gas is suitable for the given application or not, or whether it is necessary to perform a gas processing or a gas exchange. For gas mixtures based on N2 / CleanAir / DryAir, there might not yet be any standards or limit values available. It is recommended that, before measuring the gas quality, the requirements and the limit values are verified with the respective manufacturer.Battery life If the lithium-ion rechargeable battery is fully charged, the analytic instrument can perform at least 5 measurements with the “pumping back” function. The number of the battery-powered pump-back cycles is largely dependent on the container pressure of the gas to be measured.The GA11 sends a warning message on the display when battery is low.If the instrument is not connected to the mains in time, it will shut down automatically in order to prevent damages and data loss. In the mains operation, the battery is charged and the instrument can be switched on again at the same time and operate without restrictions.Power and charging indicatorsThe front control panel has two LEDs which indicate the charging status (red) or mains operation (green). The front control panel has two LEDs which indicate the charging status (red) or mains operation (green). During the charge cycle, the charging indicator lights up red. If no charge cycle occurs (rechargeable battery full or fault), the charging indicator blinks red. A fault occurs if the rechargeable battery is defective and the GA11 cannot therefore be switched on outside of mains operation (→ see chapter 7.1 “Maintenance”).
