The HA5 Current Probe is the best choice for measuring very small loads and the outputs of Current Transformer (CT) step-down circuits.
Designed to monitor permanently mounted CTs (Current Transformers), the range of 20 milliamps to 5 amps gives the best resolution and accuracy for measurement circuits and step-down transformers.
The range from 20 milliamps to 5 amps is a great choice for accurate high-resolution monitoring of small 3 phase loads. [NOTE: For high accuracy non-intrusive testing of single phase loads, use the 120ADP accessory, for high accuracy of very small loads (down to 2 milliamps) use the HA-GFD].
The compact size of the HA5 allows it to be used in very confined spaces.
The light weight and special measurement range of the HA5 makes it a great choice for a second set of current measurement probes for your analyzer.
