VERIFY 10 MMHG PRESSURE TRANSDUCER ACCURACY (KRYPTON UNITS ONLY)
Verifying the 10 mmHg transducers’ accuracy requires the use of:
l 004-09814-00 Paroscientific Pressure Calibration Standard OR
004-09603-00 Crystal Pressure Gauge
1. Install the pressure calibration standard on one of the sample ports. If using the Paroscientific
gauge, connect it to the analyzer's RS-232 port.
2. Manually pressurize the analyzer, including the one sample port, to 9 mmHg ± 0.5 mmHg.
3. Go to Unit [n] > Calibration >Pressure Scale (10 mmHg).
4. Click From Reference and enter the reading from the Paroscientific gauge, or enter the pres-
sure reading from the pressure calibration standard. Press Enter.
5. Reduce the system pressure to 4.50 mmHg ± 0.25 mmHg.
6. Record the value for the 10 mmHg transducer and the pressure calibration standard.
7. Calculate the differences between the pressure calibration standard and the analyzer trans-
ducer.
8. Record the serial number of the pressure calibration standard on the data sheet.
9. Remove the vacuum gauge and pressure calibration standards.
10. Re-install the filter frits in the sample port 1 &2.
