TEST LEAD (Standard Accessory) Testing of the grounded lead should be avoided, unless absolutely necessary. If a part such as the lead must be tested, be sure to connect the low-side crocodile clip (black) to the grounded end of the lead. Connecting the highside crocodile clip (red) to the grounded end of the lead may result in electric shock or damage to the equipment.
