The altitude calibration mode can only be entered when the GSI 38 is powered up from
its “off’ state while the program mode pushbutton, PROG is depressed. Hold the
PROG pushbutton for approximately five seconds.
STEP 1
When entering the altitude mode the display will read as follow:
Altitude Mode
ECV 2.0
cm
3
9.99
Standard
(E71) is displayed in the bottom right corner of the display until the probe is in the 2.0
cm
3
cavity.
STEP 2
Place the probe into the 2.0cm
3
cavity provided with the instrument and check cm
3
value against the altitude correction table for accuracy.
STEP 3
If the measured volume is not within the published table value +/- .1cc, then the
operator should exit the altitude mode by pressing the PROGRAM MODE pushbutton
and contact field service. Providing the measured volume agrees with the published
table +/- .1cc, the operator may proceed with the altitude adjustment.
STEP 4
With the probe still in the 2.0 cm
3
cavity, select the page pushbutton to enter the
custom calibration mode. Custom will appear on the fourth line of the display.
