stop the scanning. By default, selecting the Scan button will test each pin in each 2700 resistance
range before stepping to the next pin. To change which range parameter (voltage, resistance or
frequency) is incremented during scanning refer to figure 2-8.

From the V Ω Hz menu, select VOLT for the 2700 voltage to be incremented while scanning,
select RES for the 2700 resistance to be incremented while scanning or select FREQ for the
2700 frequency to be incremented while scanning. Deselect all of the buttons and the 2700S will
