If the lockout is active, the gauge will now prompt for entry of
the lockout code. Refer to “STEP BY STEP: ENTERING A
LOCKOUT CODE (When Prompted)” on page 22.

→ key to accept the desired
value.
The value is accepted, and the register is closed.

11. P4 – User Scale All Models
The user scale feature is provided in addition to the standard Engineering Unit choices, to allow the display of
measured pressure in any Engineering Unit. The full scale value of the sensor is linearly re-scaled to the value
entered in this register. This is particularly useful for displaying linear tank levels in volumetric or mass units.
For example, a 20 PSIG gauge is programmed to read out in feet of water head by entering 46.22 in the P4
register. This sets the gauge to read from 0 to 46.22 feet of water, when User Units are selected as the
Engineering Units (46.22 feet of water at 20°C is equal to 20 PSIG).
User Engineering Units are selected when ALL Engineering Units are flashing during the Engineering Unit
selection process. Once selected, in Measure Mode, all Engineering Units are cleared from the display to
denote user-units.
