LINE SCALE 3, digital dynamometer certified as PPE LINE SCALE 3 is crafted from a single block of high-strength aeronautical aluminium (LY12CZ), giving it an impressive MBS of 90kN! It is structurally solid as there are no mechanical parts that can be damaged. LINE SCALE 3 has been approved as PPE, so that even industrial professionals can use it on a daily basis. A single solution for a product that is fast (1280Hz) and smart, as it stores data recorded during sessions. Versatility With an MBS of 90kN, LINE SCALE 3 is useable as an anchor/distribution point for highline or rope access. The large, omni-directional, transverse load-proof eyelets can easily handle multiple connectors. Configuration The displayed unit of measurement (kg, lb, kN) and auto-off time can be selected and saved according to user preference. In addition, LINE SCALE 3 offers customizable storage speed; which provides up to 50 hours of recording time. Operating Modes NET mode: always shows the actual load, regardless of any potentially set tare. ZERO mode: shows the load value minus the tare weight. High Tech Energy Saving LINE SCALE 3 automatically switches off if no load change is recorded during the pre-set time interval. For this reason, the dynamometer does NOT calibrate its sensors to 0 when it is switched on. Instead, it immediately shows the actual load (when in NET mode). This allows LINE SCALE 3 to be switched on only when required, thus saving an enormous amount of battery and allowing it to last several months without needing to recharge it. In addition, a display power-off function has been added; which dims the OLED display but allows LINE SCALE to collect all data in the background. Accuracy The AD 24Bit pro with dual strain gauge configuration has a resolution of 1 kg with a measurement error of ±0.5% (within the 'sweet spot' area of 300 kg - 1500 kg / 3 kN - 15 kN, which is 10-50% of the maximum load). NB: below the 'sweet spot' area, the measurement error can be up to 2%. WARNING! Note that the permissible PPE working load is limited to 10kN (9x safety factor). Although the LINE SCALE 3 has an absolute WLL/SWL of 30kN and an MBS of 90kN, it cannot be used beyond 10kN in any PPE scenario.
