RPM4™ OPERATION AND MAINTENANCE MANUAL

OPERATION

To use the AutoRange function, press [AutoRange] and respond to the RPM4’s prompts.

Select AutoRange measurement mode: The screen is identical in appearance and function to the [MODE] screen (see Section 3.3.3). The choice of measurement modes offered reflects all the Q-RPT types available (Axxx, Gxxx, BGxxx) in the RPM4 system, not just the active Q-RPT.

Differential pressure measurement mode (see Section 3.3.3.1) is not available in AutoRange.

Select pressure unit of measure: The screen is identical in appearance and function to the [UNIT] screen (see Section 3.3.2).

Altitude units of measure (m, ft) are not available for AutoRange.

Enter the AutoRange full scale pressure: Enter the full scale pressure value in the <------>entry field and press [ENT]. If the full scale value entered cannot be covered by

any of the Q-RPTs available, an error message appears. If the full scale value can be covered, AutoRange proceeds to the range display.

View proposed AutoRange range: The proposed AutoRange range screen is:

1.Indication that this is a screen of the proposed AutoRange range.

2.Designator and position of the Q-RPT that AutoRange has selected to cover the AutoRange full scale and measurement mode.

3.Pressure unit of measure specified in AutoRange.

4.AutoRange full scale pressure in gauge mode and absolute mode if available. Absolute mode only if AutoRange measurement mode is absolute and full scale is less than 100 kPa (14.5 psi). Gauge mode only if the Q-RPT is a Gxxx or BGxxx or an Axxx with absolute mode turned off.

If the RPM4 has two Q-RPTs and you would like to select the other one for the AutoRange, the cursor control keys may be used to toggle between Q-RPTs selections if both Q-RPTs can handle the specified AutoRange.

Accept proposed AutoRange: To accept the proposed AutoRange and go to the MAIN RUN screen with the AutoRange range active, press [ENT] or [AutoRange]. To modify the AutoRange full scale, measurement mode or pressure unit of measure, use [ESC] to back through the AutoRange screens and make changes.

To verify or confirm the range from the MAIN RUN screen, use [+/-] or [RANGE] to view the active range (see Section 3.3.1).

See Table 6 for a listing of all selections and settings affected by AutoRange and their default values.

The BA100K Q-RPT cannot be AutoRanged.
