Questions to ask before buying a PID
Does it come with instructions for this PID?
Not only on boot up but in the menus Does it display two rows of four zeros (0000/0000) as needed?
Will it allow changing the LCK setting,
Will it allow the P setting to be set to 0000,
Will it allow access to and changes to the COD and the COD1 menus?
When changes are made is the setting saved permanently?
Do the instructions explain how to display 1/10 and 1/100 of a degree?
Do the instructions explain how to adjust the number of degrees variance (over or under temperature) the
PID will allow?
Is this PID designed to work with an SSR?
