Memory Operations Store Saving Display or Data Log In Store Mode three memory operations can be set-up: None, Snapshot and Datalog. Refer to Using SETUP for details. Store Operations (Screen Snapshots) To store any display (menu displays excepted), press the STORE key. This saves the current display to the next available location. Supporting text (10 characters) may be appended. Twenty memory locations are available on a cyclic buffer.
Memory Operations Datalog Data Log Operations Data Log is a special application of store mode which enables the calibrator to either automatically log displays at preset time intervals or to manually log a display on operation of the STORE key. Logged data is written to a user specified file. To set-up a Data Log file, proceed as follows. • • Select a task, other than BASIC. If using ADVANCED, set-up the required output parameters. Use SETUP to select Data Log from the Store Mode Menu (See page 36).
Memory Operations Datalog Recall Data Log Files To recall a Data Log file to the display, ensure that DATA LOG is selected from the SETUP menu and proceed as follows: Data Log files can be displayed either as text (stored screens) or in graphical form. To display as text, proceed as follows from the File Summary menu. Select Auto Step to automatically review each screen at 1 second intervals or use the left and right cursor keys to manually review.
Memory Operations Datalog Uploading Data Log Files WARNING THE RS232 INTERFACE MUST ONLY BE USED IN A SAFE AREA Connect the RS232 socket of the instrument into either the COM1 or COM2 port of the PC. Ensure that the RS232 parameters set in the PC match those of the instrument. The RS232 parameters of the instrument can be checked as detailed on page 38. Set up a file on the PC to receive the data, (e.g.) in the Windows® Terminal program. To upload a file, proceed as follows.
Memory Operations Datalog Downloading Procedure Files (DPI 615 instruments only) WARNING THE RS232 INTERFACE MUST ONLY BE USED IN A SAFE AREA Complete test procedures may be downloaded from a PC to the DPI 615 instrument via the RS232 port. A procedure consists of a number of Druck Universal Command Interface (DUCI) commands that are usually assembled by a linking management software application (e.g.) Druck Intecal. Before downloading a procedure, the instrument must be in the REMOTE mode.
Memory Operations Datalog Running Procedure Files (DPI 615 instruments only) To run a procedure, make sure that the instrument is set to Store mode, Data Log (see page 36), and proceed as follows: After selecting F1, proceed by entering the User ID and Serial Number and then select F1 (Continue) and follow the on-screen procedural instructions: When the test procedure for a given UUT has been completed, the result of running the first test is stored as an AS FOUND file. This file cannot be overwritten.
Memory Operations Datalog Recalling Data Files (DPI 615 instruments only) Data or results files generated by running procedures are stored in the instrument’s data log directory. To recall a data file to the display, make sure that DATA LOG is selected from the SETUP menu and proceed as follows: Use the cursor keys to select either the AS FOUND option or the AS LEFT option for display. AS FOUND is the result of the first run of a procedure and AS LEFT is the result of the last time the procedure was run.
Using Setup General SETUP mode is available in all modes except BASIC and permits the changing of the following instrument parameters. • Store Mode - None, Snapshot, Data Log. • Contrast. • Settings - Units, Language, RS232 parameters, Powerdown and Calibration Routines (Refer to page 41 for calibration details). • Date and Time (Real Time Clock).

Using Setup Powerdown Select POWERDOWN from the SETTINGS menu and proceed as follows: If selected to TIMER mode, following a period of inactivity, the instrument automatically powers off after the preset TIMER period. If selected OFF, auto power off is inhibited and once switched on, the instrument remains ON until it is manually switched OFF. Calibration Refer to page 41 for a full description of the calibration procedures. 39 K0430 Issue No.
Using Setup Date and Time (Real Time Clock) Date Format To set-up the real time clock, select DATE & TIME from the set-up menu and, using the key, set the required date format: Set Date Select DATE from the DATE & TIME menu and, using the cursor keys, change the date as shown below. The up and down keys change the numerical value of the selected digit (indicated by the underline cursor) and the left and right keys select the required digit position.
Calibration General The instrument is supplied by the manufacturer, complete with calibration certificate(s). A calibration period of 12 months is recommended. The actual calibration interval depends on instrument usage and the total measurement uncertainty acceptable for the specified application.
