P412 Preset Character (Toggle)
If P412 is enabled, it will add a ‘P’ to the beginning of the tare parameter on the display and
transmits if the last tare value was entered manually by the user (numeric entry). P167 needs to
be enabled in order to key in a tare value. A ‘P’ will not be added if the last tare was performed by
pressing the tare key or if the tare value is zero (even if the zero value was manually entered by
the user). The ‘P’ prefix stands for “Preset”. When P412 is disabled, the unit will never show 'P'
before tare no matter how tare is entered.

Select display control option. Choose from On, Off or Auto. The auto setting helps conserve

If P420 is set to Off or selection 0, you can turn on the display by holding down the [ZERO] key
upon power up.
