APPLICATIONS
The needs for accurate low resistancemeasurement are well
known and verydiverse. They range through receiving, inspection of components
toground bonding and welded joints.Typical end users include utilities,telecom,
railroads, aviation, manufacturing facilities, and process controlplants.
Applications include, but arenot limited to, making dc resistancemeasurements
for:
• Switch and contact breaker resistance
• Busbar and cable joints
• Aircraft frame bonds and static
control circuits
• Integrity of welded joints
• Intercell strap connections on
battery systems up to 600 V peak
• Quality control of resistivecom ponents
• Small transformer and motor winding resistance
• Rail and pipe bonds
• Metal alloys welds and fuse resistance
• Graphite electrodes and other composites
• Wire and cable resistance
• Transmitter aerial and lightning conductor bonding
