What are the precautions when using a Insulation Piercing Connector multimeter to measure voltage or current?
When measuring, do not touch the metal part of the test lead with your hands to ensure safety and measurement accuracy. When measuring DC current, pay attention to the polarity of the measured current. First, point the measurement to determine the direction to avoid the pointer from hitting the meter head in reverse. When measuring higher voltage or large current, do not turn the conversion switch with power on to avoid arcing and damage to the contacts of the conversion switch. After the measurement, set the conversion switch to the highest AC voltage or neutral position.
