6 Control lamp for measurement range overflow "OL"
This red LED lights up if
• the measured current exceeds the adjusted measurement range
• short current peaks exceed the measurement range
• the measurement is not valid due to other reasons.
7 Direction arrow
The arrow symbol shows the reference flow direction of the DC current to be
measured. If the current clamp is operated in a way that the DC current
flows in inverse direction to the displayed reference direction, the current
clamp outputs a negative voltage.
