FRONT-PANEL MODES By default, the number of primary turns is assumed to be 1. In this example: Np : Ns 1 : 0.365 To display the actual number of turns as measured, enter the number of primary turns by pressing the appropriate buttons on the numeric keypad. (Note: Only numbers and a decimal place can be entered for Np.) E.g., Np = 1000 Np : Ns 1000 : 365 The number of primary turns entered will be retained by the tester until the ‘More’ softkey is selected, i.e., if you exit LCR (FIX) and re-enter or if you select TRL, LL or C, the value for Np remains the same. 6.1.3 INSULATION RESISTANCE Insualtion resistance measurements involve applying a relatively high DC voltage to the part under test in order to measure a high value of resistance. Because of the high voltages involved, IR meaurements operate in a slightly different way to other tests. There is a separate voltage setting menu and ON / VOLTECH ATI USER MANUAL PAGE 6-13
