When the [RANGE] function key is first pressed, the active reference pressure
transducer (RPT) and range are displayed. For example:
1. Identifies RPT currently in use ( <Hi> ).
2. Identifies current range ( <1> , <2> or <3> ) of the RPT.
3. Range designator.
4. Full scale pressure value in the current units for the RPT
and range number when used in gauge <g> or absolute
<a> mode.
5. Units of measure (the units of measure currently active
for this range).
Pressing the [+/-] key or pressing the [RANGE] key again causes the screen to step
through the other available ranges in sequence: Lo to Hi and back to Lo. For example:
1. Identifies RPT ( <Hi> ).
2. Identifies range of the RPT ( <1> , <2> or <3> ).
3. Range designator.
4. Full scale pressure value in the active units of measure
for the RPT and range number when used in gauge <g>
or absolute <a> mode.
5. Units of measure (the units of measure currently active
for the range).
Range full scale limits are given in the pressure unit that is currently active for that
range. Use [UNIT] to change pressure units if desired (see Section 3.2.1).
The active range can only be changed when the system is vented. If [ENTER] is pressed
while in the RANGE function when PPCK+ is NOT vented, the display indicates <Vent
system fully to change range>. Pressing the [VENT] key causes PPCK+ to vent and return
to the RANGE function when the VENT is complete.
3.2.1.1 RANGE SPECIFIC FUNCTIONS AND SETTINGS
PPCK+ functions and settings are range specific. They are set and stored for each
range so that changing them when in one range does not change them in the
other ranges. When you return to a range, you will find the settings you left.
Functions and settings that are NOT range specific are:
