Step 1
1. To begin Step 1 of the calibration process, select ZERO . Enter the actual pressure
applied and press ok .
a. Wait until the zero procedure completes. This may take several minutes. When
the Calibrator completes Step 1, the Calibrator will request which sub-range of
the triple range sensor is to be calibrated. Use the arrow keys to highlight the
desired range and hit OK.
b. The system will then prompt the operator to enter the number of points that
should be included in the calibration. Typically, it is recommended to select
3 points up and 3 points down. This will generate a calibration procedure that
includes atmosphere, 50%, 100% in the increasing direction and then 50% and
atmosphere in the decreasing direction for the sub-range of the sensor being
calibrated. When the Calibrator completes Step 1, the Calibration, Step 2, screen
will appear.
Step 2
Note
The number of steps noted in this example is 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.
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 Calibrator. As pressure is
admitted into the Test Port, the
Measured pressure
on the Calibrator’s screen will
change accordingly.
2. When the Measured pressure stabilizes, use the Calibrator’s numeric keypad and OK
to enter the actual pressure applied by the calibration standard. Do not enter the
Measured pressure reported by the Calibrator . 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 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, number 1, if necessary
Step 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 Calibrator. As pressure is
admitted into the Test Port, the Measured pressure on the Calibrator’s screen will
change accordingly.
2. When the Measured pressure stabilizes, use the Calibrator’s numeric keypad and OK
to enter the actual pressure reported by the calibration standard. Do not enter the
Measured pressure reported by the Calibrator. 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.
