Connecting Current Probes
Types of current
cables
Several Dranetz-BMI current probes can be used with the Current Input Module -
Model No. 61MAC of the 61000. The following are two types of current cables
available for connecting to the current input channels A, B, C, and D.
• CT Series Adapter Assembly.
• Four Channel Current Probe Cable Assembly (for TR25xx probes).
Types of current
probes
A variety of current measurement probes and transformers are available that can be
connected to these cables in a number of ways.
For instance:
• TR25xx clamp-on current probes that provide a broad range of current
measurements.
• Multiple probes and adapter cables that are currently used with Dranetz-BMI
equipment i.e. Flex Core models and Hall-effect probe models.
Typical current probes are illustrated on page 2-19. A diagram showing current
connection to a single phase circuit for general hookup is also provided on page 2-21.
Safety
precautions
The following safety precautions apply to current probe connections.
• DO NOT attempt to measure current in any circuit in which the circuit to ground
voltage exceeds the insulation rating of the current probe (600 Vrms max).
• Make sure the jaws of the current probe are tightly closed. Keep mating surfaces
clean and free from foreign matter.
