Introduction; Incompatible Fluke 45 Commands - Fluke 8845A Programmer's Manual

Introduction

Due to differences in their design, the 8845A and 8846A (collectively the 884XA) cannot
emulate all the functions and features of the Fluke 45. Some functions are compatible but
are not implemented the same in the 884XA meters.
This appendix covers the differences with, a list of commands that are not compatible,
and information on those functions that will respond differently by the 884XA.

Incompatible Fluke 45 Commands

Due to their design differences, there are Fluke 45 function and modifier commands that
the 884XA meters will not execute. Whenever a non-compatible command is detected by
the 884XA meters, they will generate a -102, syntax error. Table 33 lists Fluke 45
commands that are not compatible with the 8845A and 8846A.
