Page 27: Maintenance
Operating Manual - Load Cell Calibrator Maintenance 16.0 Maintenance 16.1 Opening your Calibrator There are a few cases in which you may have to open your calibrator. 1. To change the battery pack. 2. To change the fuse. In order to open it, place it face down on a flat, hard surface and unscrew the four screws as shown. -
Page 28: Battery Care
Maintenance 16.5 Battery Care Your calibrator is powered by rechargeable Lithium Ion batteries. 1. The batteries can be recharged hundreds of times but will eventually fail. 2. Only use dealer approved batteries that contain a temperature sensor. 3. Do not store your calibrator in extreme heat, above 50°C as the batteries may become unstable and rupture. -
