PRF-914B High Resistance Miniature Concentric Ring Fixture Set
a. To accommodate the PRF-912B or 914B center electrode a single
gold contact point is positioned at the center of the PRV-913B
Verification Test Surface.
b. The center position is connected to the ten individual outer ring
race pads by the ten, 10 megohm resistors.
II. 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.
NOTE
This manual displays Cautions and Warnings alerting the user to hazardous operation and ser -
vicing conditions. CAUTION or WARNING headings throughout this publication flag this infor -
mation, where appropriate. Follow all Caution and Warning instructions at all times.
A. Use of Measurement Power Supply
1. The PRF-914B 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 touch -
ing 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 me -
tallic parts of the PRF-914B fixture or cable assembly when power is applied to the probe.
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.
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.
WARNING
Never exceed the maximum applied operating test voltage of 100 volts
