Digital Pressure Gauge SERIES CPG 2500 10. Calibration The CPG 2500 automatically adjusts the pressure reading for the effects of temperature and non-linearity within the calibrated temperature range of 15-45°C. The process is referred to as dynamic compensation because each reading is so adjusted before it is output to the display or to a communication bus.
Digital Pressure Gauge SERIES CPG 2500 10.4 Setup The following illustration for calibration setup shows a typical setup for either local or remote calibration for an absolute or gauge pressure instrument. The ‘Optional Computer’ is required only for performing a remote calibration. The ‘Pressure Standard’ is normally a deadweight test instrument, and the ‘Volume Controller’ refers to a hand operated variable-volume pressure vernier device.
Digital Pressure Gauge SERIES CPG 2500 10.5 Calibration The calibration screen is password protected, and will require the operator to enter a password before proceeding. Touch the channel setup key. Then touch the adjust tab. Next, press the key and the password entry screen will appear. The password installed at the factory is 1 2 3 4 5 6. The operator can change this password as described in 10.5.2 - Utility Tab.
Digital Pressure Gauge SERIES CPG 2500 10.5.1 Sensor Tab Press the Sensor tab to view information about the installed sensors. The radio buttons allow the operator to select which sensor information is displayed and which sensor is active in the calibration screens. 10.5.2 Utility Tab The Utility tab allows the user to perform certain administrative features for the CPG 2500. 10.5.2.1 Zero and Head Correction The padlocks indicate if the feature is accessible from the Channel Setup/Adjust tab.
Digital Pressure Gauge SERIES CPG 2500 10.5.2.2 Restore Factory Cal Press OK to restore the factory settings. 10.5.2.3 Change Password 1. Press this key to change the password. A number entry screen will be displayed. Enter from one to six digits for a new password. As each number is pressed it appears in the password window. ! CAUTION: The password is seldom used and is easily forgotten. After a change, write down aned save the new number. If the password is lost, contact mensor. Caution 2.
Digital Pressure Gauge SERIES CPG 2500 10.5.3 Edit Tab Press the Edit tab to adjust the calibration with known data. 10.5.4 Calibrate Tab Press the Calibrate tab to adjust the sensor by applying a calibrated pressure. Follow the instructions below according to which procedure is required. Procedure 1 should be used when you have ‘as found’ data. (If you pressed “Restore Factory Cal” you will have to re-generate the data. The values can be entered with no pressure applied to the external port).
Digital Pressure Gauge SERIES CPG 2500 10.5.4.1 Procedure 1: For ‘as found’ data 1. Press the Calibrate/Edit tab. The pressure points should be within 20% of the minimum and maximum range of the channel. 2. Enter the points from the pressure standard in the first column (desired). 3. Enter the ‘as found’ readings of the 2500 in the second column (actual). Press [apply]. The second column will now contain the data from the first column. The readings should now be correct. 10.5.4.
