The APM uses the same reliable, high accuracy, digital temperature compensated technology found in the nVision, housed in a new rugged enclosure with an integrated cable to con- nect to your JOFRA calibrator. In addition, you can connect the APM to a hand-held pressure calibrator to increase the range of that calibrator. Supported JOFRA Calibrators The Crystal APM has been engineered to work seamlessly with many of the most popular JOFRA calibrators. Below is a list of compatible JOFRA calibrators. • AMC910 • ASC300 • ASC301 • ASC321 • ASC-400 • ASC-400 BARO • HPC500 • HPC502 • HPC600 Note: This manual includes information on the APM CPF modules only. For details on the operation of JOFRA calibrators, please refer to their User Manuals. What's Included Each unit includes an APM CPF pressure module, a fitting of your choice (NPT, BSP, or M20), NIST traceable calibration certificate, and AMETEK product CD. Crystal Engineering calibration facilities are A2LA accredited, (#2601.01) which is internationally recognized by ILAC. Note: A CPF adaptor fitting is not included with 15 000 psi / 1000 bar / 100MPa APM models. The module connector is compatible with 1/4 medium pressure tube system, HIP LM4 and LF4 Series, Autoclave Engr SF250CX Male and Female Series. See our CPF Data Sheet for additional adapter fittings. APM CPF Series Operation Manual Operation  2 Operation „„„„„ ADVANCED PRESSURE MODULE (APM) INSTRUCTIONS Pressure Connection Crystal CPF System: Medium Pressure Female (MPF) (1/4” medium pressure tube system with 7/16-20 threads). See our CPF Brochure for further information.  U.S. Patent No. 8,794,677 CPF o-ring size and material: AS568A-012, Viton 80 durometer (P/N 3981). For most applications CPF Fittings can be hand tightened for use up to 10 000 psi / 700 bar / 70 MPa (no tools required). Wrench tightening is recommended (to achieve a metal to metal cone seal) for applications where chemical compatibility of the process fluid and the o-ring are a concern, or for pressures above 10 000 psi / 700 bar / 70 MPa. We recommend a tightening torque of 120 in-lbs ±20 in-lbs. Please note this is only a fraction of the typical torque required to seal a 1/4” NPT fitting. If a torque wrench isn’t practical to use, the fittings can be assembled as follows: Hand tighten fitting fully until the cone has bottomed out. Tighten an additional 20º using a wrench. Apply a small amount of media-compatible lubricant to the gland threads and male cone to increase fitting life, reduce the likelihood of galling, and promote sealing. ! CAUTION: To achieve CPF maximum allowable working pressures no o-ring substitutions are allowed. See our CPF brochure and CES-003 CPF Safety Guide available from the website at ametekcalibration.com for further detail. ! WARNING: Pressurized hoses and associated equipment are potentially dangerous. Slowly bleed off pressure from the system being pressurized prior to connecting or disconnecting the Crystal APM. Measuring Vacuum All ranges of the APM can be used to measure moderate vacuum. Ranges 300 psi / 30 bar / 3 MPa and below are calibrated for vacuum use. When measuring pressure less than ambient barometric conditions, a minus sign (-) will appear. ! CAUTION: The APM is not recommended for continuous use at high vacuum. Overpressure Conditions The APM will read pressure up to approximately 110% of the rated pressure range. All JOFRA indicators will display overpressure warnings. For example, above 110% of the range, “OL” will display in red on an ASC-400, indicating an Overload Alarm. The zero function does not affect when the “OL” is displayed to indicate overpressure. So depending on the zero value, it is possible that the display will indicate “OL” without the maximum pressure being displayed. For instance, if a 100 psi APM is zeroed when 30 psi is being applied, it will indicate that the overpressure condition has been reached at 80 psi. (i.e., 110% x 100 psi – 30 psi = 80 psi). Overpressure can affect accuracy, but the effect is only temporary unless the sensor has been damaged. See Specifications for maximum allowable overpres- sure ratings.

APM CPF Series Operation Manual Communications  6 Communications The APM interface uses a command – query – response protocol. Using this protocol the user can access the pressure measured by the module, as well as control and monitor the status of all the essential functions of the module. „„„„„ INTERFACE DESCRIPTION The APM can be remotely controlled using a PC terminal or computer program running the module in an automated system. A USB-based serial port con- nection is required for remote operation. The serial port connection also powers the module. Once connected, a user can write programs with Windows-based languages like Visual Basic. „„„„„ SETTING UP THE SERIAL PORT FOR REMOTE CONTROL A USB to serial cable (available with part number APMCAL KIT) is used for serial communications from the APM to a computer. To connect the module to a computer, attach it to a USB-to-serial cable, connected and installed on a PC. Connecting the module to the cable will automatically power it on. Note: Be sure to set the appropriate COM port in your communications software: 9600 Baud; No parity; 8 Data bits; 1 Stop bit; No hardware flow control; Software flow control (XON/XOFF) recommended. To verify the module has connected successfully, enter *IDN? within the communications program. This command will return information from the module. „„„„„ USING COMMANDS Command Types The APM may be controlled using commands and queries. All commands may be entered using upper or lower case. Refer to Remote Commands and Error Codes for all available commands. The commands are divided into the following types: X Module Commands Module Commands are used only by the module. For example, VAL? asks for the values displayed on the module display. X Common Commands Common Commands are standard commands used by most devices. These commands always begin with “ * ”. For example, *IDN? tells the module to return its identification. X Query Commands Query Commands ask for Information, and always end with “ ? ”. For example, VAL? returns the current pressure reading of the module. APM CPF Series Operation Manual Communications  7 Command Processing The data entered into the module is processed as follows: • Data is taken as 7-bit ASCII. • Characters are discarded if their decimal equivalent is less than 32 (space), except 10 (LF) and 13 (CR). • The most significant data bit is ignored. • Upper or lower case is acceptable. • More than one command (Compound Commands) may be entered on one line. Commands are separated by semi-colons. For example, PRES_UNIT KPA;FAULT? Response Data Types The data returned by the module can be divided into four types: X Integer For most computers and controllers, integers are decimal numbers ranging from -32768 to 32768. For example, FAULT? could return an integer of 117. Refer to the Error Codes table for more information on error codes. X Floating Floating numbers have up to 5 significant figures and exponents. For example, VAL? might return 25.345 PSI. X Character Response Data (CRD) Character Response Data is data returned as keywords. For example, PRES_UNIT? might return PSI. X Indefinite ASCII (IAD) Indefinite ASCII are any characters followed by a terminator. For example, *IDN might return CRYSTAL, APM003C, 678123, R130000.31/R08009.13. Module Status X Error Queue If an error occurs due to invalid input or buffer overflow, its error code is sent to a 15 entry error queue. An error code is read from the queue with the FAULT? command. When the error queue is empty, FAULT? returns 0. The error queue is cleared when power is reset or when the clear command *CLS is entered. X Input Buffer The module stores all received data in a 128 character input buffer, which accommodates varying character input speeds.. If the input command/symbol stream is too fast, the module will send the XOFF command when the input buffer is full. When the module is able to continue to receive commands, it will generate the XON command. The module can receive up to eight more characters after the XOFF command has been sent. If more characters are received, it will stop receiving, clear the input buffers, interrupt command execution, and flag the error 120 (Input Buffer overflow). APM CPF Series Operation Manual Communications  8 In order to avoid interruptions in the command execution process: • Turn on software ( XON / XOFF ) flow control on the PC side. • Avoid long command lines (lines more than 96 characters). • Send the *CLR command before starting the communication procedure. • Check the error buffer sending the FAULT? command after the communication procedure is finished. „„„„„ REMOTE COMMANDS AND ERROR CODES The following tables list all the commands, and their descriptions, accepted by the APM. Common Commands Command Description *CLS (Clear Status) Clears the error queue. *IDN? (Identification Query) Returns the manufacturer, model number, and firmware revision of the module. *RST Resets the module to the power up state. Module Commands Command Description DAMP Turns Damp on or off. DAMP? Returns if Damp is on or off. FAULT? Returns the most recent error code. PRES_UNIT Sets the pressure unit for the indicated display. PRES_UNIT? Returns the pressure unit from the indicated display. VAL? Returns the measured values. ZERO_MEAS Zeros the pressure module. ZERO_MEAS? Returns the zero offset of the pressure module. CAL_STORE This command must be sent anytime a parameter has changed. APM CPF Series Operation Manual
