Step 3. After the warm-up period is over, using the Pressure Standard, generate a pressure of
1.000 inHg absolute. Allow the pressure to be stable at 1.000 inHg for 2 minutes and take the
reading on the Pitot side (PtinHg) of the 6300. This is the first of your “Before” calibration
adjustment reading. It will indicate the zero drift since the previous calibration.
Note:
If your Standard cannot generate 1.000 inHg abs., the lowest possible pressure below
4.000 inHg abs. will be acceptable.
Step 4. Generate a pressure of 50.000 inHg absolute, allow the pressure to stabilize for 2
minutes and take the reading on the Pitot side (PtinHg) of the 6300. This is the second of your
“Before” calibration adjustment reading. It will indicate the zero plus slope drift since the
previous calibration. Leave the pressure at 50.000 inHg while you perform the next step.
Note: If your Standard cannot generate 50.000 inHg abs., any pressure between 45.000 and
50.000 inHg abs. will be acceptable.
If you do not wish to make a calibration adjustment, but just want to verify the accuracy of the
6300, please skip to Step 10.
Step 5. To make a calibration adjustment for the Pitot port, on the 6300, move to the the
CALIBRATION screen using the NEXT SCREEN key and enter the password. The calibration
screen appears as follows:
CALIBRATION
Pt inHg Ps inHg
Vacuum: 1. ________ 3. ________
F.S. : 2. ________ 4. ________
Step 6. Ensure that the pressure generated by the Standard on the Pitot port is still 50.000
inHg. Select item ‘2’ using the keypad on the remote unit and then enter the value 50.000 in
item 2. This indicates the full scale point for the calibration. If you make an error while
entering data, press “CLR”. Do not press “CANCEL”. You may re-enter the value any
number of times.
Note: If your Standard cannot generate 50.000 inHg abs., any pressure between 45.000 and
50.000 inHg abs. will be acceptable. Enter the value of the generated pressure.
Step 7. Now generate a pressure of 1.000 inHg with the Standard. Allow the pressure to
stabilize for 2 minutes, select item ‘1’ using the keypad on the remote unit and then enter the
value 1.000 in item 1. This indicates the vacuum point for the calibration. If you make an error
while entering data, press “CLR”. Do not press “CANCEL”. You may re-enter the value any
number of times.
