Quick Start Function Summary
Instructions for ASHCROFT
® GC51
This function allows the user to establish a linear relation-
ship from the standard “psi” unit to any user defined unit.
Note: See menu schematic at end, must be in “Linear
Display Mode” option within “Setting Mode”, this is
noted on the screen by
Use $ # keys to move between “Linear Display Mode”
and “Pressure Display Mode.”
Note: Values shows are from example in I&M manual.

simulate applied pressure, can be accessed either
through Pressure Display Mode or Linear Display Mode.
See “Complete Setting Mode Menu” at end. Loop Check
is noted on the screen with a prefix “
( ”. The display
is indicating in actual units and starts at the zero
(4mA) point.
If $ button continues to be pressed, the linear display
will auto-increment by linkage between the linear display
and the analog output. By continuing to press # button,
auto decrement will occur. Release the button at the
desired indication.
Notes shown below are from I&M manual.
Notes: Actual values shown are based upon the examples
shown in the I&M Manual.
Changes made within the Setting Mode are saved
by returning to Measurement Mode before powering
the unit “off.”
