Run AutoZ by COM2
AutoZ by COM2 allows the value of ZSTD (see Section 3.4.1, PRINCIPLE, How
AutoZ Works) to be read automatically from a DHI RPM1, RPM2 or RPM3 connected
by RS-232 interface to the PPC2+ COM2 port.
To access run AutoZ by COM2 press [SPECIAL] and select <1AutoZ>,
<4run>,
<2COM2>. The display is:
1. Pressure reading, units and mode of the
active RPT range.
2. Active range indicator.
3. Pressure reading of the RPM connected to
PPC2+’s COM2 port.
When Ready (<*>), press [ENTER]. The next
display is:
The new ZOFFSET is the ZOFFSET calculated from this execution of run AutoZ.
Press [ENTER] to activate the new ZOFFSET and return to the main run screen.
Press [ESCAPE] to maintain the old ZOFFSET and return to the main run screen.

Run AutoZ by RngL3
The AutoZ by RngL3 choice is only available if the current RPT is an absolute, Hi RPT
and there is an absolute Lo RPT in the PPC2+. Run AutoZ by RngL3 allows AutoZ to
be run on a Hi RPT range using Lo RPT range 3 (L3) as the source of ZSTD (see
Section 3.4.1, PRINCIPLE, How AutoZ Works).
To access run AutoZ by RngL3 press [SPECIAL] and select <1AutoZ>,
<4run>,
<3RngL3>. The display is:
1. Pressure reading, units and mode of the
active Hi RPT range.
2. Active range indicator.
3. Pressure reading of Lo RPT range 3 (L3).
