Guardian Range
Calibration
The design features a simple form of calibration adjustment against a scale plate. This allows the users to either order units with a specific setting, or stock a mid range setting and then calibrate to suit the application. Calibration is performed on the opposite side of the switch to the electrical connections, and can be set safely with the switch supply live. On removal of the adjustment cover a small grub screw can be loosened allowing the adjusting ring to be turned with a small tommy bar or allen key. The setting is read from the centre of the red indicating ring against the calibrated scale plate.
Calibration procedures for dual microswitches and adjustable switching differential switches are detailed on the operating and maintainance instructions supplied with each switch.
