The MultiPro IQ Express Docking Station is an Automatic calibration station and data download center for the MultiPro gas detector. Just place the detector into the MultiPro IQ Express and the MultiPro Express does the rest. The MultiPro IQ Express identifies the instrument and performs a quick battery test before moving onto a bump test. If the detector fails the bump test, the MultiPro IQ Express automatically performs a full span calibration of the detector without further intervention from the user. Once the instrument has passed the bump test or span calibration, the IQ Express automatically tests the audible, visible and vibrating alarms before downloading the instrument data. Once all the tests have passed, the IQ Express Dock will show 'ready' on the display, letting you know that the detector is ready to go.
