ZERO FUNCTION
During any programming operation pressing the ESC key will
cause the HHC to exit any special display mode or, step back one
programming level if in Programming Mode.
PORT SELECT function is used in several programming appli-
cations including zero, min/max, tare and damping. This allows
the user to choose between installed modules to which an action
is to be performed. PORT SELECT is enabled following the ini-
tialization of a desired function such as zero. The selected mod-
ule(s) will be indicated by having a rectangular box surrounding
the measurement indication. Pressing the PORT SELECT key
repeatedly will allow the user to select the Channel 1 , Channel
2 or both channels if applicable. When desired channel (s) are
selected the ENTER key is pressed to finalize the selection.
The default Data Storage mode is manual and is described in
section 14g and 15f. The HHC is capable of storing pressure,
temperature, voltage or current data for any combination of
installed modules, voltage or current inputs that are active, up
to three simultaneous data points. Each data record will include
a time stamp and up to three measurement values. Headers in
the Datalog report label columns with date, user-programmable
module description (default values are Channel 1, Channel 2,
Ext.) and the engineering unit of measure. Up to 16,000 records
can be recorded. Data records are grouped in Datalogs which
can be manually initiated or automatically logged at user defin-
able time intervals between 100 milliseconds and 24 hours.
Utilized to remove zero offset, up to 10% of full scale range, when
zero pressure is applied.
1. Press the ZERO key. PORT SELECT MENU is entered with
the Channel 1 module selected.
2. Use the PORT SELECT key to select Channel 1, Channel 2 or
both Channels.
3. Press ENTER to zero the selected module or modules, or
press ESC to cancel and return to Measurement Mode
A module must be installed in the HHC base unit to be zeroed.
Additionally, it must be a pressure module, and must be within
10% of full scale of its factory programmed zero.
In the event an attempt is made to zero a module that is absent,
or which is not a pressure module a warning will be displayed in
the notice area stating:
“CH(X) not a pressure mod”.
In the event an attempt is made to zero a module that is more
than 10% of full scale from its factory programmed zero, a warn-
ing will be displayed in the notice area stating:
“CH(X) zero out of bounds”
Press the Back Light key to toggle the light on/off. A user pro-
grammable back light auto off timer can be used to preserve
battery life. Press any key to reset the backlight auto off timer.
