Cautions & Warnings
As with any electrical device, use proper electrical precautions and measurement practices
to avoid personnel shock. Read this manual in its entirety before attempting to use these
products.
A. Use of Measurement Power Supply
1. The PRF-912B is a high performance micro probed designed for use with a
maximum input voltage of 100 volts
. As such, it is capable of delivering an
annoying shock to any person touching the spring-loaded contacts when they are
energized.
a. If used with the PROSTAT PRS-801 Resistance System, the current capability of
the micro probe instrument combination is limited to a very low, typically
harmless level. However, a distinct hazard exists in the operator’s
reaction
to a
possible shock.
b. To avoid shock, operating personnel should not touch the electrodes, or any
exposed metallic parts of the PRF-912B fixture or cable assembly when power is
applied to the probe.
c. The designed operating voltage limit for normal auditing and laboratory
measurements is 100 volts. Exceeding 100 volts greatly increases the risk of
personnel shock hazards.
d. Only qualified instrument repair and test personnel should exceed the 100-volt
operation limit, and then do so
only under controlled conditions using
maximum precautions against personnel shock
.
CAUTION
To avoid electrical shock,
Do Not Touch
the fixture test electrodes, test bed, or exposed metal
BNC connections when power is being applied to the probe.
WARNING
Never
exceed the maximum applied operating test voltage of 100 volts.
