STEP BY STEP: P4, USER SCALE
Step Action
Display
Notes
1. Preceding/Trailing zeroes are determined by where the user places the decimal point. When opening
a register, the value is always shown padded with trailing zeroes.
2. Only 4 digits are available for editing (the ½ digit is not provided), plus the decimal point and
negative sign (negative is not applicable to register P4). This limits keypad value entries to
±9,999,
and also limits the available decimal point resolution (depending on the magnitude of the value). The
serial interface provides much more flexibility.
3. After steps 2 and 3, the Backspace
← key will abort the process and return to Measure Mode.
4. The display does not have a physical decimal point that can be illuminated in the least significant
position (to the right of all digits on the display). Thus, if the decimal point is in that particular
position, there will be no decimal point blinking (which may be confusing). When scrolling through
the decimal point selection, it is important to take note that none blinking is a viable setting, and will
be seen in the scrolling sequence.
5. After step 9, the PRGM/Enter
→ key will again open the register for edit.
6. During any programming operation, if there is no keypad activity for approximately 1 minute, the
operation is aborted and the gauge returns to Measure Mode unchanged.
12. P5 – SETPOINT Options Set Point & Current Loop Models Only
This register defines the output action for SetPoint and Current Loop models. Note that if an output is disabled
by this register, the setpoint value in its corresponding register (P6, P7) has no impact. Also note that a setpoint
value (P6, P7) may be 0.0, which is a viable output setting; thus, in order to disable control action, register P5
should be used to define the desired action.
In Measure Mode, the indicators “SET1” and/or “SET2” will illuminate when the corresponding relay is
energized. The “4-20mA” indicator will illuminate when the Current Loop output is enabled. In Program
Mode, the indicators “SET1”, “SET2”, and “4-20mA” will illuminate as appropriate to assist when scrolling
through the register’s choices. Note that if P5 is set for active, the outputs will continue to update even in
Program Mode, according to the currently programmed values.
