Introduction
This chapter contains the instructions for removing major assemblies in
the Agilent 53210A/53220A/53230A Counters. To install a new or repaired
assembly, reverse the removal instructions.
This chapter provides the following disassembly/reassembly procedures:
CAUTION Only open the counter at a Static-Safe Workstation to prevent
electro-static damage to the instrument. Do not replace
assemblies with the counter turned on or AC power connected to
the instrument. Damage to components can occur.
CAUTION DO NOT swap the motherboard, the processor board, or the front
panel board from one instrument to another. These boards
contain model number and serial number information that
uniquely identifies a specific unit, and boards that are
mismatched to the instrument may result in problems with its
performance, licensing, serviceability, importability/exportability
or warranty.
