User manual FLUKE COMPASS FOR PPC V2.0

[. . . ] COMPASS® FOR PPC/RPMTM Pressure Calibration Software User's Manual © 1998-2000 DH Instruments, Inc. High pressure liquids and gases are potentially hazardous. Energy stored in these liquids and gases can be released unexpectedly and with extreme force. High pressure systems should be assembled and operated only by personnel who have been instructed in proper safety practices. Information in this document is subject to change without notice. [. . . ] [DMM] Tab FEATURE Model (required entry field) Serial Number (required entry field) Identification (optional entry field) Calibration Due Date (optional entry field) Remote Interface (drop-down selection list) RS232 Settings (conditional display panel) IEEE 488 Address (conditional entry field) Communications Test (action button) SCPI Command Set (check box for RS232 or IEEE 488) Only the pressure reference and the DMM support this field. The value entered should represent the next required calibration date of the instrument. No special formatting is expected or checked in this field however, entering the date in a consistent format including the full year, month and day is recommended. The value entered is logged in the run test data files and can be included in reports. The choices available are <RS232> and <IEEE 488>. To set up the DMM for remote communications, select the interface that is on the DMM. When an interface type is selected, the rest of the <Remote Interface> and <Command Information> panels change as appropriate to accommodate definition of the interface characteristics. COMPASS generates an error when <None> is selected. If the remote interface selection is RS232, the <RS232 Settings> information is shown. When creating a new reference device, the settings are loaded with COMPASS default settings. Port settings are listed baud rate, parity, data bits, stop bits. Clicking on any setting field causes the <RS232 Settings> editor to appear (see Section 8. 2. 6). Select the correct settings for the DMM and click <OK> when ready. If the remote interface selection is IEEE 488, the <IEEE 488 Address> entry field is shown. When creating a new reference device, the IEEE 488 address is set to the default address 10. The address can be edited directly in the entry field. Clicking on the communications test button causes COMPASS to attempt to send the command specified by the <Command Type> selection to the DMM. The results of the command or an error display. If the <SCPI> option is checked, the "*IDN?" command is sent to the DMM instead of the current command selection. Checking the SCPI Command Set check box indicates to COMPASS that the DMM communications follow SCPI (Standard Commands for Programmable Instruments) protocol. When the SCPI check box is checked, the <Command Information> fields show <N/A> and cannot be edited. COMPASS will use the commands <MEAS:VOLT:DC?> to read voltage and <MEAS:CURRENT:DC?> to read current without removing any leading characters. [. . . ] Device that can be used by COMPASS to switch the output of multiple DMM data acquisition type DUTs to a single DMM so that data can be taken from multiple DUTs during a test. Control conditions of DHI PPC Pressure Controller/Calibrators. A ready condition indicates that the target pressure has been reached and ready criteria have been met. Not ready indicates that ready criteria have not been made. [. . . ]
