This mode automatically determines the most appropriate measurement range for the testing that is being conducted. To manually force the meter to measure in a different range, use the "RANGE" button 1.
- Page 9 OPERATING INSTRUCTIONS CONNECTING TEST LEADS Do not test if leads are improperly seated. Results could cause intermittent display readings. To ensure proper connection, firmly press leads into the input jack completely. INCORRECT CORRECT TESTING IN CAT III / CAT IV MEASUREMENT LOCATIONS Ensure the test lead shield is pressed firmly in place.
- Page 10 ENGLISH OPERATING INSTRUCTIONS AC CURRENT (LESS THAN 400A) AC Current is measured by pressing the clamp trigger to open the clamp and placing it around a current-carrying wire. When measuring, care should be taken to ensure that the clamp is completely closed with trigger fully released, and that the wire passes perpendicularly through the center of the clamp in line with...

Page 17: Maintenance
MAINTENANCE BATTERY REPLACEMENT When the Battery Strength Indicator shows low battery strength( batteries must be replaced. 1. Remove screw from battery door. 2. Replace 3 x AAA batteries (note proper polarity). 3. Replace battery door and fasten securely with screw. To avoid risk of electric shock, disconnect leads from any voltage source before removing battery door. - Page 18 ENGLISH CLEANING Be sure meter is turned off and wipe with a clean, dry lint-free cloth. Do not use abrasive cleaners or solvents. STORAGE For everyday storage turn meter off, disconnect test-leads, and store in the carry case provided for the meter. NOTE: Storing the meter for any period of time in the carrying case with the test-leads inserted is not recommended.
