RPM4™ OPERATION AND MAINTENANCE MANUAL
© 2004-2007 DH Instruments, a Fluke Company Page 40
If the inactive RPT is equipped with SDS Self Defense System (see Section
3.2.7), SDS will almost certainly be CLOSED when the RPT DISPLAY is activated.
SDS can be OPENED on the inactive RPT using [SPECIAL], <4SDS> (see Section
3.5.4). In differential or parallel measurement mode, SDS can be opened
simultaneously on both Q-RPTs using [SDS] (see Section 3.3.8).
The RPT DISPLAY is the default display in differential measurement mode.
When the RPT display is active, executing a range change to a range on the
inactive Q-RPT makes the inactive Q-RPT the active Q-RPT. The DISPLAY
defaults back to Rate ( Section 3.3.6.2).
To go to a DISPLAY other than RPT, press [DISPLAY] and make a new
DISPLAY choice (see Section 3.3.6).
3.3.6.5 Hi/Lo
PURPOSE
To activate the Hi/Lo DISPLAY.
See Section 3.3.6, Principle..
OPERATION
To activate the Hi/Lo DISPLAY press [DISPLAY], <5Hi/Lo>. Pressing <5Hi/Lo>
resets the Hi/Lo values and returns to the main run screen with the Hi/Lo
DISPLAY active.
With the Hi/Lo DISPLAY active the main run screen is:
1. Highest pressure observed since Hi/Lo reset.
2. Lowest pressure observed since Hi/Lo reset.
99.1135 psi a zHi
H 99.2254 L98.0098
The Hi/Lo values change each time a new Hi or Lo pressure is observed.
The Hi/Lo record can be reset at any time by pressing [ENT]. This allows a
Hi/Lo reset without going back through the DISPLAY menu.
If the pressure measurement unit, mode or range is changed while the Hi/Lo
DISPLAY is active, Hi/Lo resets.
To go to a DISPLAY other than Hi/Lo, press [DISPLAY] and make a new
DISPLAY choice (see Section 3.3.6).
