Calibration
1. Full (HI-LOW) calibration requires a standard manome-
ter calibrator and should be performed by a professional
calibration laboratory. Contact Sper Scientific.
2. To perform a ZERO calibration, disconnect all tubes and
do not apply pressure to the connectors.
3. Press F1 (MEAS) followed by F3 (Cali) - “Calibration” is
displayed.
3. Press F4 (ZER0) and “Cali: 0.000 PSI” will be displayed.
4. Press F4 (ENTER) again - after approximately 3 se-
conds the meter will display “OK” to indicate that the
calibration was successful.
5. If NG (No Good) is displayed, perform the calibration
again. If the meter fails to calibrate after three (3)
attempts, it should be returned to Sper Scientific.
