RPM4™ OPERATION AND MAINTENANCE MANUAL

To access run AutoZ by COM2 press [AutoZ], <2COM2>. The display is:

1.Real time pressure reading (without head correction), pressure unit of measure and measurement mode of the active Q-RPT.

2.Active Q-RPT position designator.

3.Real time reading from the RPMx connected to RPM4’s COM2 communications port.

Pstd,0:0.00000

 

Observe the displayed pressures and verify that they are stable. When ready, press [ENT] to cause AutoZ to run. RPM4 logs both readings and calculates a new AutoZ offset value. The display is:

Press [ENT] to activate the new value of Poffset or [ESC] to start over.

Old Poffset: 0.0 Pa

New Poffset: 3.1 Pa

For RPM4 to communicate with an RPMx connected to its COM2 port, the RPM4 and the RPMx RS-232 interfaces must be set up properly (see Section 3.5.2). If, the RPM4 is unable to communicate with an RPMx via COM2 when running AutoZ by COM2, it times out after 6 seconds and displays <RPM NOT detected>.

The value of Poffset is always displayed and entered in Pascal (Pa).

Run AutoZ by Lo RPT

AutoZ by Lo RPT is available only if the active Q-RPT is the Hi Q-RPT and there is an Axxx Lo Q-RPT. AutoZ by Lo RPT allows the Lo Q-RPT in an RPM4 to serve as the AutoZ reference (source of Pstd,0) (see Section 3.5.1,  PRINCIPLE). The Lo Q-RPT is read and the new Poffset is calculated automatically.

To access run AutoZ by Lo RPT press [AutoZ], <3Lo RPT>. The display is:

1.Real time pressure reading (without head correction), pressure unit of measure and measurement mode of the active Q-RPT.

2.Active Q-RPT position designator.

3.Real time reading from the Lo Q-RPT.
