This article relates to LongMons, BlockMons, and LeafMons designs.
All the above cell monitors are calibrated in-house against a standard. They are valid to 2 decimal places as per our specification. They are calibrated at room temperature and the range may increase but the accuracy is sufficient for them to function effectively in their operating range.
Extract from above document the headers are Minimum, Typical and Maximum.
We removed the ability for customers to do their own calibrations back in 2015 when we moved to WatchMon Toolkit as customer calibrations frequently caused more problems than they solved and the accuracy was sufficient for the purpose the cell monitor was designed for.
If you wish we are willing to test and recalibrate your cell monitor/s free of charge but you will need to pay shipping to us both ways. We can ship Australia Post as a letter if you wish to reduce shipping cost as the shipping cost can sometimes outstrip the device cost.
