7- 1
Customer Maintenance
This manual supports maintenance of the amplifiers and probes.
Service Strategy
The amplifiers have some mechanical and electrical parts that may be replaced
by the customer. This section describes the preventive maintenance and repair
procedures.
The probes can be repaired to component level. Information on troubleshooting
and repair begin on page 7--13.
Preventive Maintenance
The TCPA300 and TCPA400 Current Probe Amplifiers and current probes
require little maintenance during normal use. The primary maintenance involves
cleaning accumulated dirt from the probe body and, if necessary, cleaning the
exposed core surfaces in the probe jaw.
Protect the instrument from adverse weather conditions. The instrument is not
waterproof.
CAUTION.
To avoid damage to the instrument, do not expose it to sprays, liquids,
or solvents. Do not use chemical cleaning agents; they may damage the
instrument. Avoid chemicals that contain benzene, toluene, xylene, acetone, or
similar solvents.
Clean the exterior surfaces of the instrument with a dry, lint-free cloth or a
soft-bristle brush. If dirt remains, use a cloth or swab dampened with a 75%
isopropyl alcohol solution. A swab is useful for cleaning in narrow spaces
around the controls and connectors. Do not use abrasive compounds on any part
of the instrument.
CAUTION.
Avoid getting moisture inside the instrument during exterior cleaning
and use only enough solution to dampen the cloth or swab. Use a 75% isopropyl
alcohol solution as a cleanser, and rinse with deionized water.
