USER GUIDE 3000A AC Flexible Clamp Adaptors Models CA3010 and CA3018
Introduction Thank you for choosing the Extech AC Flexible Clamp Adaptor that can measure up to 3000A AC. A standard Digital MultiMeter (DMM) in mV AC mode can be used to display the current measurement when the CA series Adaptor is connected to the DMM. The CA3018 is the 18” (45.7cm) clamp version and the CA3010 is the 10” (25.4cm) clamp version, otherwise both meters are the same. These devices are professional CAT IV 600V CAT III 1000V instruments.
Safety Information To ensure the safe operation and service of the meter, follow these instructions closely. Failure to observe warnings can result in severe injury. WARNINGS WARNINGS identify hazardous conditions and actions that could cause BODILY HARM or DEATH. Individual protective equipment should be used if HAZARDOUS LIVE parts in the installation where measurements are to be carried out could be accessible.
CAUTIONS CAUTIONS identify conditions and actions that could cause DAMAGE to the meter or equipment under test. Do not expose the meter to extremes in temperature or high humidity. Safety Symbols that are typically marked on meters and instructions This symbol, adjacent to another symbol, indicates the user must refer to the manual for further information.

Meter Power The meter is powered by two (2) AAA 1.5V batteries (located in compartment on bottom of meter handle).
AC Current Measurements WARNING: Ensure that power to the device under test is OFF before starting this procedure. Switch power to the device under test ON only after the clamp has been safely attached to the device under test. CAUTION: Do not move fingers above the LCD at any time during a test. 1. 2. 3. 4. 5. 6. 7. 8. 9. Switch OFF the Clamp Adaptor, the DMM, and the device under test. Connect the Clamp Adaptor to the DMM banana jacks using the supplied banana plugs.
Maintenance WARNING: To avoid electrical shock, disconnect the meter from any circuit and turn OFF the meter before opening the case. Do not operate the meter with an open case. Cleaning and Storage Periodically wipe the case with a damp cloth and mild detergent; do not use abrasives or solvents. If the meter is not to be used for 60 days or more, remove the batteries and store them separately.
