Fluke 6270A - Jog Pressure; Vent and Abort

Jog Pressure
The Jog function is most often used when calibrating mechanical gauges such as
a dial gauge and the user wishes to change the pressure until the mechanical
gauge indicates a cardinal point. The user can then read the higher resolution
Calibrator to determine the actual pressure value when the mechanical gauge is
indicating a cardinal point. To jog the pressure, rotate the jog wheel clockwise or
counter-clockwise to increment or decrement the pressure by the lowest
significant digit of the active measurement resolution. For example, if 0.01
measurement resolution is set and the unit is psi, turning the Jog Wheel will
increment the pressure by 0.01 psi per knob detent.
Vent and Abort
Touch Vent to completely vent the applied pressure at a controlled rate. When
Vent is pushed, the Product prompts for confirmation before venting to prevent
accidental venting or accidently canceling tests. If Vent is touched when a test is
in progress and the dialog is confirmed, the test immediately stops and the
Product vents all pressure in the system. To protect the operator and to remove
pressure from the system before maintenance, the vent is also actuated when
the front panel is opened to remove pressure from the system.
The Product has an automatic pressure-relief function called Auto Vent that
releases pressure if it exceeds upper or lower pressure limits. See the Auto Vent
section for more information on this feature.
For emergency pressure relief, the red Abort button on the bottom right of the
front panel, immediately vents all pressure from the system and cancels any
program or task in progress. In addition, the Product enters a safety mode and
disconnects remote operation. The Product stays in this mode until exiting safety
mode by confirming the on-screen dialog.
Caution
To avoid equipment damage, use the Abort button for
emergency situations only. Abort vents pressure as quickly as
possible without restriction. This rate of pressure drop could
damage some sensitive UUTs.
