The Magnetic Wand is used for accessing menu options and programming functions of several CETCI gas detection devices without having to open the enclosure. It can also be used to initiate calibration. The wand activates the magnetic switch inside the enclosure, triggering it to carry out an action. Prompts can be followed on the display. Non-intrusive calibration is particularly useful when in a wet or dirty environment. The LPT-A, SCC and DCC have magnetic switches on the front of the device and the LPT-P, LPT-B and LPT-M have magnetic switches on the side of the device. For exact locations, refer to the Operation Manual of the specific device.
