In order to ensure the COLTS accuracy measurements are as accurate as possible, SP also supply a calibration verification rod that is specifically designed to check the COLTS calibration accuracy.
The calibration verification checking process is quick and simple. Open the COLT app on your smart mobile device, connect to the COLT device via Bluetooth, and select ‘Cal Check’ within the ‘Rope’ menu section of the app. Place COLT on a flat surface and then zero the measurement on screen. Place the 20 inch steel rod in the centre of all 3 sheaves and apply loading arm until it is fully engaged with the magnetic catch. The force measurement reading should read as 3000lbs (within an accuracy range of <3%>).
If the measurement is greater than 3% difference (1.27te to 1.45te (2800lbs to 3200lbs) then you will need to contact SP and arrange for the COLT to be sent back to SP for recalibration. The process is as simple as that!
