calibrated. When the DPC completes Step 1, the Calibration step 2 screen will
appear.
Step 2
NOTE: The number of steps noted in this example are based on the operator selecting
a 3 points up and 3 points down procedure. If a higher or lower number of points
is specified by the operator, the actual pressures that the 7615 calculates will very
to reflect these changes.
2.1 To begin Step 2, use the calibration standard to Apply the mid-point pressure of
the sub-range of the sensor being calibrated requested by the DPC. As pressure
is admitted into the Test Port, the Measured pressure on the DPC’s screen will
change accordingly.
2.2 When the Measured pressure stabilizes, use the DPC’s numeric keypad and OK
to enter the actual pressure applied by the calibration standard. Do not enter the
Measured pressure reported by the DPC. If necessary, use the CLEAR key to
correct a mistake in the edit field. If the actual pressure applied is acceptable,
the Calibration step 3 screen will appear.
NOTE: If the actual pressure is outside of the tolerance for the requested mid-point
pressure, Error —222 Data out of range will occur. Acknowledge this error by
selecting OK, then re-enter the actual pressure, repeating step 2.1 if necessary.
Step 3
3.1 To begin Step 3, use the calibration standard to Apply the high-point pressure of
the sub-range of the sensor being calibrated requested by the DPC. As pressure
is admitted into the Test Port, the Measured pressure on the DPC’s screen will
change accordingly.
a. When the Measured pressure stabilize, use the DPC’s numeric keypad and OK to
enter the actual pressure reported by the calibration standard. Do not enter the
Measured pressure reported by the DPC. If necessary, use the CLEAR key to
correct a mistake in the edit field. If the actual pressure applied is acceptable,
the Calibration step 4 screen will appear.
NOTE: If the actual pressure applied is outside of the tolerance for the requested
high-point pressure, Error —222 Data out of range will occur. Acknowledge this
error by selecting OK, then re-enter the actual pressure, repeating step 3.1 if
necessary.
Step 4
4.1 To begin Step 4, use the calibration standard to again Apply the mid-point
pressure of the range of the sensor being calibrated requested by the DPC. As
pressure is admitted into the Test Port, the Measured pressure on the DPC’s
screen will change accordingly.
4.2 When the Measured pressure stabilize, use the DPC’s numeric keypad and OK to
enter the actual pressure reported by the calibration standard. Do not enter the
Measured pressure reported by the DPC. If necessary, use the CLEAR key to
