Setup Unit - Instrutech The Hornet IGM402 User Manual

Instruction Manual
- CG1 ONLY
This mode displays only the measured pressure from convection gauge 1 (CG1) in a single screen as
shown in Example Ex 1B.
- CG2 ONLY
This mode displays only the measured pressure from convection gauge 2 (CG2) in a single screen as
shown in example Ex 1C.
DISPLAY INT [Factory default =3 SECONDS]
-
This is the time it takes for display screen to change to the next screen. Display interval can be selected
from 2 to 10 seconds.
FLIP SCREEN [Factory default = NORMAL]
-
This allows the user to select a NORMAL display or have the pressure measurement data displayed upside
down. When the IGM402 is mounted upside down, this selection is used to invert the display screen 180
degrees for user convenience. Note - When UPSIDE DOWN is selected, the user has to save the setting and
exit the menu before the measured values are displayed.
-SCREEN SAVER [Factory default = ON]
The Hornet uses an OLED type display which over an extended period of time can start to show divergence
between pixels that are on at all times verses pixels that are not. This could result in pixels exhibiting a
burned-in effect. To minimize the burned-in effect, a screen saver function can be activated by
programming the SCREEN SAVER menu selection to ON. With the screen saver function turned on, the
display appearance changes every 12 hours. The display will appear in the normal mode with a dark
background color for the first 12 hours and will then switch to a back-lit background color for the next 12
hours. If you like to have the 12 hour period for the normal display mode to start at a specific time of the
day, simply access the SCREEN SAVER menu and change setting to OFF and then ON again. This initiates the
screen saver function immediately.

5.8.2
- UNITS [Factory default = TORR]
Select from TORR, mBAR or PASCAL. Units selected are used for all other settings.
- DEFAULTS [Factory default =MENU TO EXIT]
The module can be returned to the original factory settings by using the ENTER key to set factory defaults.
Note - If you set factory defaults, you must re-enter the actual IG sensor SENSITIVITY value marked on the IG
sensor, set atmosphere and zero for both CG1 and CG2, and reprogram other parameters as required.
- CLR IG ERROR [Factory default = OFF]
When the IGM402 ionization gauge (IG) experiences an error condition such as OVERPRESSURE, emission
failure, etc.,
the Ion gauge filament will turn off and the module will stop measuring pressure.
will be displayed on the IGM402 screen showing the error. This is intended to prompt the user to determine
what the error condition is before the filament can be turned on again. Once the cause of the error has
been determined and resolved, the error must be cleared before the filament can be turned on again. The
CLR IG ERROR allows the user to clear the IG error using the front panel soft-keys, regardless of whether the
IG CNTL mode below is set to Front Panel, Digital Input or RS485.
