15Preparing for MeasurementThe easyScan hard- and software have been set up according to the instruc-tions in the section (Un)packing and Installation.Preparing and installing the STM tipThe STM tip can be prepared and installed by yourself. This is the mostdifficult part of your preparations. It usually needs patience and some prac-tise to get the first good tip. Only an accurately cut tip enables optimalmeasurements. Therefore, cutting and installing should be carried out withgreat care.- First ensure that the cutting part of the wire cutters (figure components, 8a), the half-round pliers (8 b) and the pointed tweezers (8 c) have beencleaned with ethanol. Touch the Pt/Ir wire (8 e) with these tools only.- hold the end of the wire firmly with the pliers and cut a piece off approxi-mately 5mm long.- Still holding this piece of wire with the pliers, place the cutters at the freeend, as obliquely as possible. (See picture below)- Close the cutters until you can feel the wire, then pull in the directionshown below. The tip needs to be torn off rather than cleanly cut through,in order to get the required sharp tip.half-roundplierswire cutterpulling and cuttingdirectionwirePREPARING FOR MEASUREMENTPREPARING AND INSTALLING THE STM TIP |
