RUSKA 7350
Users Manual
6-4
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,
number 1, if necessary.
Step 3
1. To begin Step 3, use the calibration standard to Apply the high-point pressure
requested by the 7350. The Measured pressure on the RUSKA 7350’s screen will
change accordingly.
2. When the Measured pressure stabilizes, use the RUSKA 7350’s numeric keypad and
OK to enter the actual pressure reported by the calibration standard. Do not enter the
Measured pressure reported by the RUSKA 7350. 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, number1, if necessary.
Step 4
1. To begin Step 4, use the calibration standard to Apply the mid-point pressure
requested by the RUSKA 7350. As pressure is to be applied into the Test Port, the
Measured pressure on the RUSKA 7350’s screen will change accordingly.
2. When the Measured pressure stabilizes, use the RUSKA 7350’s numeric keypad and
OK to enter the actual pressure applied by the calibration standard. Do not enter the
Measured pressure reported by the RUSKA 7350. If necessary, use the CLEAR key to
correct a mistake in the edit field. If the actual pressure applied is acceptable, the
Calibration complete screen will appear.
Storing the Coefficients
Note
In addition to saving the calibration coefficients to the RUSKA 7350’s
memory, the user is advised to separately record the calibration coefficients
and store this “backup” in a safe place.
Step 5
Calibration is complete. To exit the calibration procedure without storing the calibration
coefficients in memory, press CANCEL. To store the calibration coefficients in memory,
select DONE.
Step 6
Press PREV. to return to the main screen.
Once the calibration procedure is complete, the user is advised to record several pressure
readings. If there are any significant errors at these points, then an error was probably
made in generating one of the calibration pressures, and the calibration procedure should
be repeated.
