3.5/ AUTO OFF

The PAC 11 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 ’
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  at the same time as setting the switch ’ from
the OFF position to the 1 mV/A or 10 mV/A position. If the green indicator
‘ flashes whilst the zero reset button is being pressed, this indicates that
the auto off function has been inhibited.
