Calibration Caps (pack of 5)
Calibration is done as a first step every time the PS is turned on.
Calibration is done by simply reading the calibration cap once.
The calibration cap is secured to the tip of the PS.
If the calibration cap becomes discolored, chipped or dirty the PS will not calibrate
correctly and thus not measure properly.
A new Calibration Cap should then be used.
