Warning

• When uninsulated conductor is measured, pay attention not to cause short circuit between clamp head and measured object.
• As the meter is sensitive to mechanical stress to different extent, do not release the trigger suddenly, otherwise the reading will be affected in a short time.
• To ensure accurate measurement data, the conductor to be measured must be at the center position of clamp head (A area), if it is deviated (B or C area), an additional reading error of ±2% need to be added to the specified accuracy.
• The buzzer will make sound as out-range alarm when measuring current over 1000A.

Probe usage

TESTING IN CAT III MEASUREMENT LOCATIONS

Ensure the test lead shield pressed firmly in place. Failure to use the CAT Ill shield increases arc-flash risk.

TESTING IN CAT II MEASUREMENT LOCATIONS
CAT III shields may be removed for CAT II locations. This will allow testing on recessed conductors such as standard wall outlets. Take care not to lose the shields.
