300 AMP AC CLAMP ADAPTOR

OUTPUT VOLTAGE: 1mV AC Per 1A AC

CATII 600V

CA300

Model CA310

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.

Safety

Safety Symbols

This symbol, adjacent to another symbol or terminal, indicates the user must

refer to the manual for further information.

This symbol indicates that double insulation is used.

WARNING: This indicates that a potentially hazardous condition which, if not avoided,

could result in death or serious injury.

Safety Precautions

1. WARNING: Improper use of this meter can cause damage, shock, injury or death.

Read and understand this manual before operating the meter.

2. Inspect the condition of the test leads and the meter itself for any damage before

operating the meter. Repair or replace any damage before use.

3. Do not use on non-insulated conductors at voltages greater than 250VAC rms or DC.
