Does the tacho head record the exact same info as what’s on your card ?

At the start of my shift I put my card in, did checks, drove to jet wash, then to trailer and finally onto a bay then I went for a break, when I returned I noticed that I hadn’t clocked up any drive time on the Tacho but on the dash computer (I understand that this is only a trip computer) it stated 3 minutes driving and I wondered if I had been pulled and they downloaded from the Tacho head would it have shown this movement or would it simply match my printout ■■

how long was your break ■■

do a printout and see what that says

Were those 3 movements less than 30 seconds into each full minute?

I am thinking that modern digis record what was done for the most of each individual full minute …

I meant to do a printout and look but forgot, I’m laid on the settee watching Thomas the Tank engine for the hundredth time today and was just wondering :grimacing:

It is a modern Tacho so there will have been no more than 30 seconds in a minute driving, I just wondered if the Tacho head recorded any movement at all or just did the same as what’s on a card printout ?

if its not on the card then the tacho head will be the same. You cant have one recording one thing and the other recording something else :smiley: :smiley: :smiley: :smiley:

That’s what I thought but just wondered after seeing it was registered on the dash computer :smiley:

The VDU will record exactly the same as your driver card.

I would guess that on your vehicle the dash display is not linked to the tachograph and is a vehicle trip display run by the vehicle on-board computer, there may be exceptions but generally I’ve found that the vehicle trip meters are not anywhere near as accurate as a digital tachograph.
