See
Section
7.1.1 for tables of the
conversion
factors used by RPM4-E-DWT.
If the pressure unit selected is inWa (inches of water), the reference temperature for water
density must be specified in a separate menu (choices are 4ºC, 20ºC 60ºF). No reference
temperature selection is necessary for the unit mmWa as the only reference temperature
commonly used for mmWa is 4 ºC.
The choice of up to six units available under the UNIT function can be customized from a
wider selection by the user (see Section 3.9.6). The units available under the UNIT function can be
reset to default by reset (see Section 3.9.9.2).

[MODE]
PURPOSE
Not used in E-DWT-10000-AF’s RPM4-E-DWT A70M/A7M-AF. Measurement mode is
always gauge (difference from atmospheric pressure).

PURPOSE
To automatically set up the RPM4-E-DWT to optimize its measurement characteristics and
features for a specific, user defined pressure range of operation.
PRINCIPLE
RPM4-E-DWT A70M/A7M-AF is designed to support the calibration and test of a very wide
variety of test ranges.
The AutoRange function simplifies the task of selecting the Q-RPT best suited to cover a
specific test range and setting measurement parameters appropriately for that specific range.
These are set automatically based on operator entry of desired measurement mode, pressure unit
of measure and range full scale. The selections and settings made by AutoRange are summarized
in Table 4.
A range set up using AutoRange and all its range specific settings, may be saved for recall
using
[SETUP]
,
<1range>
(see Section 3.8.1). Saved ranges are available for later selection
using
[RANGE]
(see Section 3.7.2). If a range created by AutoRange is not saved, it is
overwritten by the next AutoRange or erased when another range is selected.
Press [ENT] from the main run screen in Rate DISPLAY mode to use the [AutoTest]
function to AutoRange the RPM4-E-DWT based on DUT tolerance (see Section 3.7.11).
