Calibration Check DPI 150

After a successful leak test, set the instrument to indicator mode:
1. Connect the pressure standard for the pressure range to be checked.
2. Set the pressure standard to zero pressure, if necessary press the zero key 

so that the instrument display shows zero.

3. Adjust the pressure standard to the 0% span pressure value.
4. Compare the pressure value of the pressure standard to the value displayed 

and record the difference.

5.  Repeat steps 3 and 4 for the 100% span pressure value.
6. If the recorded difference exceeds the tolerance in the table, the instrument 

needs a calibration adjustment.

7. Adjust the pressure standard to zero pressure.

The DPI 150 instrument has the following pressure ranges.
