5.4.5.5 Factory Calibration
NOTE:
Factory calibration establishes the instrument’s default calibration setting that is recalled when
“RESTORE FACTORY CAL” is selected from the CAL DATA menu.
1. With all covers in place, turn the instrument back ON while holding down the front panel
ENT
button to
enable the Factory menu.
IMPORTANT:
Before calibrating, allow the instrument to warm up for at least 15 minutes.
2. Perform an internal calibration as described in the H25-IR instruction manual, 3015-4342.
3. After the instrument has been calibrated, store the flow and pressure calculations of that calibration as
the default factory calibration values as follows.
a) Press
the
ENT
and
ESC
buttons simultaneously to access the Main menu. From the Main
menu, select FACTORY > SENSOR CAL > FLOW RATE to display the Flow Rate and
Pressure screen.
INT:
This line shows the flow rate in moles/minute for both the
S
earch and
M
easure modes
after performing a calibration using the internal leak source, along with showing the manifold’s
pressure drop.
FAC:
This line shows the flow rate and pressure drop values that are currently stored as the
default factory calibration values. These values are used to validate calibrations performed by
the user. A calibration error will occur if the user’s calibration and factory values differ by more
than 20%.
b) Press
ENT
to store the internal calibration numbers as the default factory calibration values.
c) Press
ESC
until the Data Display screen appears.
This completes replacing the IR Optical Bench.
