The maximum opening of the clamp head: 1.96 inches 14. LCD size: 0.78 inches×1.92 inches 15. Body color: black 16. Standard accessories: clamp meter; test pen; leather case Note: 1.During the use of the multimeter, the metal part of the test pen cannot be touched by hand, so that on the one hand, the measurement accuracy can be ensured, and on the other hand, the personal safety can be ensured. 2.It is not possible to shift gears while measuring, especially when measuring high voltage or high current. Otherwise, the multimeter will be destroyed. If you need to change gears, you should first disconnect the test leads and then measure them after shifting. 3.The measured value must be estimated before the measurement. If it cannot be estimated, the gear position measurement will be reduced from the maximum gear position. 4.After use, turn the gear knob to the highest voltage file to prevent the next use, and the gear position will not damage the multimeter correctly. And turn off the power.
