3.4/ OVERLOAD INDICATION
Detection of overload of the range of the clamp is indicated by the red light 

➄

. This

indicator flashes for a peak current greater than 60 A on the 40 A range (10 mV/A)  or
600 A on the 400 A range (1 mV/A).

3.5/ AUTO OFF
The clamp has an Auto Off feature which switches off 10 minutes after the clamp has been
switched on, without the controls being used.
When the clamp is switched off by this automatic function, the switch 

➆

 must first be set to the

OFF position before being switched on again.
This function can be overridden by the user when switching on. Simply press the auto zero
button 

➃

 at the same time as setting the switch 

➆

 from the OFF position to the 1 mV/A or

10 mV/A position. If the green indicator 

➅

 flashes whilst the zero reset button is being pressed,

this indicates that the auto off function has been inhibited.
