RUSKA 7350

Users Manual

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.

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.
