LogTag Temperature Recorders

“Why is there a need for logtag recalibration after a battery change?”

LogTag recorder products that have had their case opened have potentially been exposed to electrostatic effects. In addition, units that had their battery replaced may not have been correctly hibernated or may have suffered from memory corruption if battery voltage was critically low during use. They should therefore be validated for correct operation and performance after the battery change. The preferred way of doing this is by undertaking logtag recalibration, where ideally the product should be exposed to its full temperature measuring range.
