DS404 Docking station
ID：DS404
With the DS400 and DS404 docking stations, function tests and adjustments of portable gas detection devices can be carried out automatically, quickly and easily. They have been specifically developed for G450, G460, G888, G999 and the G222E devices. The charging function ensures that the gas detection devices are ready for use when they are needed. The DS400 can be used to insert one test gas, while the DS404 features the same technology but provides inputs for up to four test gases. Gas detection devices must be tested every working day to ensure workplace safety.

A function test ("bump test") must be carried out before each use of a portable gas detection device. If the test detects any discrepancies, the device needs to be calibrated to ensure safe operation. To make these necessary procedures as simple and time-saving as possible while still complying with the DGUV information 213-056 (T021) and 213-057 (T023), we have developed the DS400 and DS404 docking stations for our G450, G460, G888, G999 and G222E portable devices. They can be operated via the display and the keys of the inserted measuring device.
Function test and adjustment
After a switched-on gas detection device is placed into the docking station, you can select either the bump test or adjustment options. The bump test automatically checks if the alarms and response times, the time settings and test interval, and (optionally) the SD card storage of data are working as intended. This will take a maximum of 60 seconds. Before the adjustment, the zero point of the sensors is set using fresh air supply. The sensors' sensitivity is then readjusted with test gas. Depending on the device and the number of sensors, this process takes a maximum of four minutes. After each test and adjustment, the device will give you feedback about the test's success or possible errors.
Charging function
If a rechargeable gas detection device is placed inside the docking station while switched off, it will automatically start charging. Once it is fully charged, the docking station will switch to trickle charge mode to conserve the battery. The docking station is supplied with power by a 12-volt power supply unit.
