8. Fejlfinding

9. Brugertips

• For the most accurate current measurements with the clamp, ensure only one conductor passes through the jaw. ClampHvis du bevæger dig omkring flere ledere, der fører strøm i modsatte retninger, vil det resultere i en nul- eller forkert aflæsning.
• Always start with the highest range when measuring an unknown value to prevent overloading the meter.
• Utilize the 'HOLD' function when taking measurements in hard-to-reach areas where the display might not be visible during the measurement.
• The 'REL' (Relative) function is useful for nulling out test lead resistance or comparing measurements against a baseline.
