When using current clamps that do not come from the MAVOWATT range of accessories, please note that the current measurement input of the MAVOWATT 30/40/70 has a measuring range of up to 1.5 V. With current clamps with higher output voltages, the measuring range can only be used up to 1.5 V. However, the start of the measuring range is 10% of the original full-scale value.
