Sequences in negative gauge measurement mode are divided into two
segments, zero to full scale (positive) and zero to low pressure (negative).
Each segment is divided into increments using the test increment size. For
example, a test with a FS pressure of 50 kPa, a low pressure of –50 kPa and
a test increment of 20%, runs in a 0 to 50 kPa segment and a 0 to –50 kPa
segment in increments of 10 kPa.
The display is:
Test point sequence
1up 2down 3u&d 4d&u
This selection determines the order in which the test sequence increments will
execute. Selecting <1up> causes the sequence to execute starting at low point
and going to the full scale value.
Selecting <2down> causes the sequence to run starting at the full scale value
and going to low point.
Selecting <3u&d> causes the sequence to run from low point to full scale and
back to low point.
Selecting <3d&u> causes the sequence to run from full scale to low point and
back to full scale.
Sequences in negative gauge measurement mode are divided into two
segments, zero to full scale (positive) and zero to low point (negative). Each
segment is divided into increments using the test increment size.
<1up> causes the sequence to run from the low point to the full scale
pressure through zero and <2down> causes the sequence to run from full
scale to the low point through zero.
<3u&d> causes the sequence to run from zero to full scale to zero to the low
point to zero. <4d&u> causes the sequence to run from zero to the low
point to zero to full scale to zero.
The next display is the proposed AutoRange range to run the QDUT test (see
Section 3.3.4 for additional information on AutoRange).
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 QDUT
full scale and measurement mode.
3. Pressure unit of measure specified in QDUT
setup.
4. AutoRange full scale pressure in gauge mode
and absolute mode if available. Shows
absolute mode only if QDUT measurement
mode is absolute and full scale is less than
100 kPa (14.5 psi).
AutoRange A2M X1H
psi 300g/300a
The cursor keys or the [RPT] key can be used to toggle through other Q-RPTs
available to cover the QDUT specified range and measurement mode. When the
desired Q-RPT is displayed, press [ENT] to accept the proposed AutoRange.
