GfG Instrumentation, 1888-711, TX400 Test Station for G888 / G999 with Charging FunctionFeatures:Meets the requirements of DGUV information 213-056 (T021) and 213-057 (T023) as well as DIN EN 60079-29-2Suitable for the portable gas detection devices G450 and G460Data storage on microSD card, data transfer to PCMobile use (no PC - 12/24 V power supply)The TX400 test stations quickly and automatically perform the required function tests on gas detectors. Gas detection devices make a significant contribution to safety if they are tested every working day. Before each use of a portable gas detection device, its operational capability must be checked with a function test ("bump test"). TX400 test stations make this process as simple, quick, and cost-effective, while still complying with the DGUV information 213-056 (T021) and 213-057 (T023). During the functional test, the test station can be operated using the display and buttons of the inserted gas detector.Function Test and AdjustmentAfter a switched-on gas detection device is placed into the test station, the station will automatically start a function test. Within a maximum of 30 seconds, the alarms and response times are tested, the time and test interval are set, and the data is stored on a microSD card (optional). The device will then give you feedback about the test's success or, if applicable, any errors that occurred. The TX400 can also be used for sensor adjustment. Before starting the adjustment, the zero point of the sensors must be set with fresh air. The sensor sensitivity is then readjusted using the appropriate test gas.Power Supply and Charging FunctionThe test stations are powered by an external 12-volt power supply unit or by a PC (connected via USB). If a gas detection device is placed inside the docking station while switched off, it will automatically start charging. Once it is fully charged, the test station will switch to trickle charge mode to conserve battery power. A 230-volt power supply or car charging adapter is required for the charging function.
