GGU-PUMPTEST: "Gauge" menu item
This menu item is only active in conjunction with the "Distance-time-drawdown method". A legend is displayed on the output sheet showing the names of the gauges and associated markers, as well as information on the number of measured values and the distance to the wells.
Almost exactly the same dialog box opens with the same preference options as that described in the "Output preferences/Measured values" menu item. Simply proceed as described there to edit the "Gauge" element.
