Cleaning the P6864, P6880, P6960, and P6980 Compression Footprints
CAUTION.
To avoid electrical damage, always turn off the power of your target
system before cleaning the compression footprint.
Prior to connecting the probe to the target system, the compression footprints on
the target system must be properly cleaned. Clean the compression footprints
according to the following steps:
1.
Use a lint-free cloth moistened with isopropyl alcohol and gently wipe the
footprint surface.
2. Remove any remaining lint using a nitrogen air gun.
NOTE
. Use alcohol sparingly and be sure that you have removed any remaining
lint or residue with the nitrogen air gun.
Cleaning the P6864, and P6880 Probe Heads
Before connecting the P6864 or P6880 probes to the target system, ensure that
the probe heads are free from dust, dirt, and contaminants. If necessary, clean the
probe heads according to the following steps.
CAUTION.
Static discharge can damage semiconductor components in the probe
head. Always wear a grounded antistatic wrist strap whenever handling the
probe head. Also verify that anything to which the probe head is connected does
not carry a static charge.
NOTE
. Never clean the elastomers. Always replace them instead. Refer to the
Operating Basics chapter of the P68XX Series Logic Analyzer Probe Instruction
Manual for information on replacing elastomers.
