Docking station for the functional checks of portable gas detection devices

With the DS400 and DS404 docking stations, function tests and adjustments of portable gas detection devices can be carried out completely automatically, quickly and easily. They have been specially developed for the Microtector II (G450 and G460), Microtector III G888 and Polytector III G999 devices. The charging function ensures that the gas detection devices are ready for use when they are needed. The DS400 can be used to charge one test gas. The DS404 provides inputs for four test gases. Only gas detection devices that are tested every working day increase safety in the workplace.

The function test (bump test) and, if necessary, the adjustment must be carried out before each use of a portable gas detection device. To make these necessary measures simple and time-saving in accordance with DGUV information 213-056 (T021) and 213-057 (T023), we have developed the DS400 and DS404 docking stations for our G450, G460, G888 and G999 portable devices. Operation is done via the display and the keys of the inserted measuring device.

Function test and adjustment
If a switched-on gas detection device is inserted into the docking station, it is possible to select between function test and adjustment. During the bump test, checks of the alarms and response times, setting of the time and test interval, and storage of the data on an SD card (optional) are performed automatically within a maximum of 60 seconds. Before the adjustment, the zero point of the sensors is set under fresh air supply. Subsequently, the sensor sensitivity is 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 each adjustment, a feedback is given about the successful execution or possible errors.

Charging function
If a gas detection device that has been switched off is placed in the docking station, the charging process starts automatically. Once fully charged, the docking station switches to trickle charge to conserve the battery. The docking station is supplied with power via a 12-volt power supply unit.

Equipment and accessories
The DS400 and DS404 docking stations have an integrated pump to draw in test gas without pressure. A gas sampling fitting (optional) must be used for the test gas feed with a gas cylinder. The DS400 has one input for test gas (single gases or gas mixtures), the DS404 has four gas inputs. Both docking stations also provide two additional ports for zero gas or fresh air and exhaust gas. Several docking stations can be connected in series via the RS-485 ports or connected to a computer for data transfer. Documentation is provided on an SD card.

With the latest release of the DS400 configuration and download software, improvements have been made to the Certificate and Report Generator software. The newest software has been included on the installation CD ROM for the DS400 since August 2013. Below are the latest software programs. They should be extracted to the original installation folder for the DS400 software. Usually that folder is C:\Program Files\GfG\DS400\.
