SETUP SCREEN Display Unit Press the ‘Display unit’ button to change the display units of the metal loss and corrosion rate as mils or microns on the main page. Calculation Period This selection unit is for calculating the corrosion rate per year based on the set time. This can be selectable as 48 hours, 7 days, 15 days and 30 days. - Page 19 Corr. Rate Display in Mils / Yr Display indicates the active corrosion rate in selected unit (mils/microns) per year. The corrosion rate is calculated based on the metal loss over the previous hours. Timing is settable through the Settings page. For the first time after the power is turned on or the probe is changed, the corrosion rate starts to calculate after 48 hours and displays the value even if the set value is other than 48 hours.
