Introduction

Due to differences in their design, the 8845A and 8846A (collectively the 884XA) cannot
emulate all of 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 the Fluke 45, giving a list of commands that
are not compatible, and information on those functions that the 884XA responds
differently to.

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 36 lists Fluke 45
commands that are not compatible with the 8845A and 8846A.

Command
AACDC The 884XA meters do not have an ac plus dc rms current function.
HOLD The 884XA meters do not have a Touch Hold function.
HOLDCLR The 884XA meters do not have a Touch Hold function.
HOLDTHRESH The 884XA meters do not have a Touch Hold function.
HOLDTHRESH? The 884XA meters do not have a Touch Hold function.

VACDC The 884XA meters do not have an ac plus dc rms voltage function.

Dual Functions

In addition to the non-compatible functions, there are numerous dual display functions
that are not part of the 884XA meter's capabilities. Table 37 is a matrix that indicates the
Fluke 45 dual functions and whether or not they are compatible with the Meter.
