This is particularly useful for leased scales, since itprevents the scale for being used for longer than the agreed period. This menu item is only available for KMT-TM terminals(ITT). The following settings are available:“Not active” There is no restriction on the period of use of the scale (factory setting).“Leasing” The duration of use is limited to the number of days entered. Enter the number of days (1 - 999)during which the scale can be used in the "Days" menu item. The duration of use is valid as of thenext day. If the set duration of use has passed, the scale still starts up, but no longer performsmeasurements and instead displays the message that the duration of use has passed.7.15 Setting of country versionAfter replacing the analog or digital board of the scale it is absolutely necessary to check the country specific settings and toadjust them if needed. The country specific settings affect the Technician Password, keyboard map, etc. Technician PasswordEU = , US = .For this procedure please connect the scale to an PC with an appropriated cable (PC – Scale, RS232, 9-pin straight cableSub D m/f) and open a terminal program on your PC (e.g. HyperTerminal). Verify that the scale is in “Dialog” Mode and thesettings of both interface of the scale and PC correspond.Depending on your location you may need to send the SICS command “DSK_US” (for USA and Canada) or “DSK_EU” (for allother countries) to the scale. The scale will send back “DSK_A”. This means that the command had been executedsuccessfully. If this is not the case, please re-check the connection between scale and PC as well as the interface settings andrepeat this procedure again. To inquire the current status of the “DSK”, send the SICS command “DSK”. Note that each SICScommand must be terminated with CRLF (carriage return, linefeed).
