Where TUR's are > 2:1 but < 4:1, the test tolerance # is reduced by root sum square (rss) techniques. # # Fluke makes no warranty, expressed or implied, as to the fitness # or suitability of this procedure in the customer's application. # # The 90 day specifications of the 5500A are used in TUR computations. # STEP FSC RANGE NOMINAL TOLERANCE MOD1 MOD2 3 4 CON 1.001 ASK- N P F W 1.002 HEAD PRELIMINARY INSTRUCTIONS 1.003 DISP Remove the screw on the back panel of the instrument 1.003 DISP and slide the cover off.
