Process Unit 73 LF conductance conductivity controlled variable controller output current input cursor keys delay time diag Diagnostics menu enter equipotential bonding failure feed time alarm first rinsing functional check GLP GMP information display interval Conductance G [S] = 1 / R [] Conductivity S/cm = G [S] * c [1/cm] User defined variable that acts on the controller Controls limit contacts 1 and 2 Processes an input current of 0 (4) to 20 mA. The current can be displayed (in % full scale) and monitored via alarm limits. and – select entry positions or digits during number entry. User defined time until contacts ”warning” and ”failure” react to an alarm message Menu key for Diagnostics menu Displays all relevant information on instrument status Key for confirming entries To prevent considerable measurement errors when measuring ungrounded media using strayfield cells, there must be an equipotential bond between medium and measuring input. Alarm message and NAMUR contact; indicates that equipment does not function properly or that certain process parameters have reached a critical value. Failure is not enabled during ”functional check”. Monitors time during which the controller output is at 100 % User defined time during which contact ”rinsing” is closed at the beginning of a rinsing cycle NAMUR contact – always enabled when instrument does not output the selected measured value Good Laboratory Practice: guidelines for performance and documentation of measurements Good Manufacturing Practice: Rules for performance and documentation of measurements. Information text for operator guidance or indication of instrument status; marked with i . Time from beginning of one rinsing cycle until beginning of the next rinsing cycle, user defined 17–2 Technical Terms

Are activated when the value falls below or exceeds the limit, depending on the user-defined effective direction The logbook shows the last 200 events with date and time, e.g. calibrations, warning and failure messages, power failure etc. This permits quality management documentation to ISO 9000. Large measurement display in measuring mode. You can select a measured variable to be displayed. Menu key for Maintenance menu The Maintenance menu comprises all functions for maintaining the sensors and adjusting connected measuring equipment. Protects access to maintenance, can be edited or disabled on the Administrator level Controller output – controls limit contacts 1 and 2 Menu key – allows return to measuring mode from all other menus. User defined time at the end of the rinsing cycle, after opening of contact ”probe” When no menu function is activated, the instrument is in measuring mode. The selected measured value is output. Pressing always returns you to measuring mode. Pressing a menu key (, , , or ) gives access to a menu, from which you can select the corresponding functions. The menu is divided into several menu levels. You can switch between different levels by pressing the menu key or the cursor keys and . The message list shows the number of currently activated messages and displays the individual warning or failure messages in plaintext. German committee for measurement and control standards in chemical industry “functional check”, “warning” and “failure” – indicate status of measured variable and Process Unit “opl” – menu level of parameter setting. You can edit the instrument settings that have been enabled on the Administrator level. Protects access to the Operator level; can be edited or disabled on the Administrator level Menu key for Parameter Setting menu Technical Terms 17–3
