IMPORTANT SAFETY INFORMATION

Please read these instructions carefully before use and retain for future
reference.

• When using electrical appliances basic safety precautions should always be
followed.

• Use the meter only as specied in this manual, or the protection provided may be
impaired.

• Do not operate the meter or use test leads if they appear damaged, or if the meter
is not operating properly. Check before each use.

• There are no user-serviceable parts in this product. Refer servicing to qualied
personnel.

• Do not use the clamp meter in a circuit with voltage higher than 600V or frequency
higher than 400Hz.

• Be cautious when working in an environment with exposed conductors. Contact
with conductors may result in electric shock.

• Use caution with voltages above 60V DC, 30V AC rms or 42V AC (peak value).
These voltages pose a shock hazard.

• Before removing the battery cover, remove the clamp meter from all energized
circuits and disconnect the lead.

• Replace the batteries as soon as the low battery indicator appears on the display.

• Fit a full set of batteries at one time.

• Remove dead batteries from the meter or if it is not going to be used for a long
time.

• Never mix old and new batteries together, or different types of batteries.

• Never dispose of batteries in a re, or attempt to recharge ordinary batteries.
