300A AC Current Clamp-on
MultiMeter Adaptor
Introduction
Congratulations on your purchase of the Extech CA310 300 Amp AC Clamp-On MultiMeter
Adaptor. With this clamp adaptor an AC current can be safely measured by simply clamping
around a single conductor. The adaptor outputs an AC mV signal that is proportional to the
measured AC current. The DMM mV reading (times 10) is equivalent to the value of the AC
current. Careful use of this device will provide years of reliable service.
