The amp shutters reduce fuse blowing and improves user safety by blocking the unused amp jacks. 

Here’s how the amp shutters affect the user operation.  When the tech moves the DMM test function from voltage to amps…..the function selector dial is blocked and it won’t move to the Amps function until the tech removes the red test lead from the V jack.  Once removed, the shutter swings up inside the DMM and then the Amps jack is opened up.  Then the red test lead can be pushed into the Amp jack.  Only after the red test lead is removed from the V jack can the operator then switch the DMM to the Amps function. 

One of the most dangerous part of operating a DMM is when a tech forgets to move the red test lead from the Amp jack back to the Volts jack and then measures AC Volts.  Hopefully, all that happens in a blown fuse, but there is a very small possibility that the fuse does not blow quickly enough, resulting in unlimited current passing through the now “in series” instrument and the DMM  in turn explodes. This is a rare occurrence, but this is why there are fuses in DMMs, to prevent them from exploding.  With the 582 meter, if the red test lead is left in the Amps jack and the user switches the DMM to AC Volts like in the above example, the dial switch won’t move.  It won't move until the user remembers to switch the red test lead back to the Volts jack and you have that potential issue corrected and avoided.
