Auto dens. corr.
Write permission
Description For switching the auto dens. corr. application on or off with an external or internal
temperature value.
Before performing a calibration (dry or wet), auto-density compensation must be switched
on if this function is to be used. As soon as "Auto dens. corr." is switched on, the field for
entering the "Process density" and "Adjust density" is disabled.
The calibration density remains the last value until it is overwritten by a calibration. The
process density remains the last value until it is overwritten when the system recalculates
the value.
Automatic density compensation is performed for the 0 to 70 °C (32 to 158 °F)
temperature range. The density values for water are used for this density compensation.
Prerequisite Level mode
