Some programmer have problem with 12f675. Do a Google on "12F675, programming problems, internal oscillator".
Keep in mind that the calibration oscillator value should be stored on address 0x3FF as a retlw instruction.
If you've erased or written to the chip already, perhaps you've already destroyed the calibration value. Do e Google search.

Hello Gianni,

i would like to ask for advice. I am doing school project. And i need to use some simple voltmeter which will measure 230V AC and then send the value by serial link. Could be your voltmeter used like that?
