Page 9: Product Description
Communication with the CPT6010 is over a serial bus, either RS-232 or RS-485. One end of the CPT6010 has a 1/4” NPT male fitting pressure port, and the opposite end has a six pin power/signal connector (J1) and a #10-32 reference pressure port (for gauge pressure only). - Page 10 Digital Pressure Transducer CPT6010 9 to18 VDC Figure 3.6 - CPT6010 Block Diagram CPT6010 Operating Instructions...

However, excessive motor or machinery vibration of the mounting surface should be avoided to further ensure stability and accuracy. For the greatest accuracy on transducers with a full scale range of less than 15 psi, set CPT6010 zero while it is oriented in its operational position. 5.5 Pressure Connections... -

For RS-232 serial port operation, connect the CPT6010 to the host computer per Figure 5.6.2 No- tice that the host TRANSMIT line is connected to the CPT6010 RECEIVE line (TX to RX), and vice versa. One limitation of the RS-232 bus is that a host can support only one instrument. See section 5.6.3, RS-485 Operation, for multiple CPT6010 operation. -

TA to RA, TB to RB, and so on. If only one RS-485 CPT6010 will be connected to the system, disregard the wiring to “CPT #1” and “CPT #2” in the illustrations. Instead, wire the computer directly to the “CPT #31” by the four-wire method. - Page 16 Digital Pressure Transducer CPT6010 Figure 5.6.3 - RS-485 Cabling CPT6010 Operating Instructions...

However, this wildcard must not be used in queries if more than one transducer is con- nected to a host. One use for the wildcard address could be when a CPT6010 is pulled out of a multi-drop setup and sent to a calibration facility for recertification. The calibration technician can communicate with the device using the wildcard address without learning or changing its assigned address. -

The temperature should be stable, and within the specified calibration range. In addition, for maximum accuracy, see that the CPT6010 is at rest on a stable platform which is free of vibration and shock, and oriented similar to its final installation attitude. At the factory the CPT6010 is calibrated vertically with the pressure port at the bottom. - Page 24 LINE SHUT-OFF REGULATOR VALVES Computer METERING VENT VALVE VOLUME CONTROLLER Serial VACUUM Cable Absolute Pressure CPT6010 PRESSURE PRESS PRESSURE NOTE: DISCONNECT WHEN VACUUM DIAPHRAGM TYPE STANDARD GAUGE RANGE IS EXCEEDED VACUUM GAUGE Figure 7.2 - Calibration Setup CPT6010 Operating Instructions...

2. Use the setup for absolute pressure shown in Figure 7.2. Apply a stable pressure value between 600 mTorr absolute and 20% of the transducer’s span.Measure the reference presure reading in the native units of the CPT6010. This reading becomes the “true pressure”. 3. Clear the current zero offset from RAM. -
