Automated Pressure Calibrator CPC 6000 8.6.2 Screen Source The CPC 6000 has two frames in which channel information can be displayed. The frame channel source can be programmed to A(left) B(right) or A(left) Delta(right) or Delta(left) B(right). Either frame can be minimized as before. 8.6.3 Configure Button In order to allow the delta function and frame channel source to be changed, a new button was added to the lower toolbar.
Automated Pressure Calibrator CPC 6000 8.6.6 Screen Source A Delta A is displayed on the left and is the leading channel. Delta is displayed on the right and is either A-B or B-A as selected. Channel B’s reading is displayed where the range information normally appears on the Delta channel. Channel B is the slave channel. Whenever the A channel is changed, the B channel setpoint is changed to maintain the differential setpoint displayed on the Delta channel.
Automated Pressure Calibrator CPC 6000 8.6.8 Delta Control Limits The default control limits for the Delta channel are the maximum limits possible. Certain combinations of setpoints will generate an illegal setpoint on the slave channel. Note that whether or not the setpoint is illegal is dependent on the measured reading of the leading channel.

Automated Pressure Calibrator CPC 6000 9.3.1 Transducer Removal VENT THE SYSTEM! Then turn off the power. Loosen the two captive screws on the front panel (Figure 3.3), and swing the panel open. Unscrew the thumb screw holding in the transducer (Figures 9.2.1B and 9.3.1). Apply a light inward pressure against the bottom of the transducer case, just below the range label, while tilting the case upward to clear the clamp plate and screw head. 5. Pull the transducer module outward, through the front opening.
Automated Pressure Calibrator CPC 6000 9.3.2 Transducer Installation To replace a transducer first make sure that it is going into the proper transducer berth in the pneumatic module. Each berth is clearly marked on the pneumatic module baseplate (see Figure 3.6). The “PRIMARY TRANSDUCER” must be the transducer with the highest pressure range. To install a transducer with the front panel already open: 1. Rest the transducer on the baseplate and the retention bar. The transducer will be tilted down slightly.

Automated Pressure Calibrator CPC 6000 10. Calibration 10.1 General The CPC 6000 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.

Automated Pressure Calibrator CPC 6000 To get to the Calibration screen press [Setup], [Sensor], and then press [Calibrate]. 10.6 Password Autozero does not require a password, however one is needed to change any date of calibration, Zero, Span, or to change the system password. The password installed at the factory was 1 2 3 4 5 6, but the user can change this as described below. 10.6.1 Change Password To change the current password: 1.
Automated Pressure Calibrator CPC 6000 3. Enter the current password. As each number is pressed an ‘*’ appears in the ‘Password’ window. When completed touch [OK] to unlock the calibration data screen. 4. The Calibration Data screen of Figure 10.6.1C is displayed. Use this screen to change the password to perform functions for 1 point calibration, 2 point calibration, restore factory cal, and head correction. Touch [Change Password] and the Change Password window appears as in Figure 10.6.1D. Figure 10.6.
Automated Pressure Calibrator CPC 6000 7. When satisfied that the new password is correct, and a written copy has been stored, press [OK] to complete the entry. The previous password is immediately replaced by the new one. 8.

Automated Pressure Calibrator CPC 6000 For a gauge CPC 6000, this automatic function will: 1. Vent the system. 2. Adjust the zero offset of each turndown that can measure the vented pressure so the turndown’s output is equal to zero. i The autozero function re-zeros sensors without storing the zero offsets through power cycling. Notice 10.8.3 1-Point Calibration A one-point calibration adjusts only the offset of the active turndown.
Automated Pressure Calibrator CPC 6000 10.8.4 2-Point Calibration A two-point calibration adjusts both the offset and the slope of the active turndown. The low point must be within 20% of the minimum range of the active turndown and the high point must be within 20% of the maximum range of the active turndown. Insure that the head correction is adjusted properly, see Section 10.9. From the unlocked calibration data screen, press the [2 Point Calibration] key as shown in Figure 10.8.4A.
Automated Pressure Calibrator CPC 6000 10.9 Head Pressure Correction The correction is accessed from the calibration menu. Four parameters may be set to reflect conditions at the operator’s site.
