Heavy instrument removal and installation
Special handling precautions should be taken for heavy instrumentation removal and installation. The
following topics describe these precautions.
Moving instruments weighing 20 pounds to 40 pounds
The following instruments require two people to move them. Some of these instruments may require
mechanical lifting equipment if they have additional options installed that cause them to weigh more
than 40 pounds or if they are located at or near the top of the system cabinet.
Some instruments in the S535 system are not heavy enough to require a two-person lift individually,
but when put together in a rack, require two people to remove and install them safely.
Instruments in the S535 system that require a two-person lift include:
4200A-SCS Parameter Analyzer with only the CVU option installed
707B Switch Matrix Mainframe with no cards installed
Multiple 2636B or 2461-SYS SourceMeter

Instruments racked together horizontally
Multiple DMM7510 Digital Multimeters racked together horizontally
The Comp-41 system computer, if not located near top of the system cabinet
Moving instruments weighing more than 40 pounds
When installing or removing equipment heavier than 40 pounds, use a mechanical lifting device. If
there is an instrument mounted below the heavy instrument, it must be removed to provide clearance
for the lifting forks. You will also need to allow for additional space outside of the cabinet for the lifting
device.
Refer to the lifting device operating manual for proper usage.
Instruments in the S535 system that require a mechanical lifting device include:
4200A-SCS Parameter Analyzer with multiple options installed
707B Switch Matrix Mainframe with cards installed
The Comp-41 system computer, if located near top of the system cabinet
