Which of the following most accurately describes the problem?

Engineering staff could be trained to read way a vehicle was driven—this was the theme of a lecture to the IRTE by Mr. F. Moon in London last week. Fairly )le analysis and comparison of tachograph ts would indicate why certain vehicles I much more fuel than others, why some more tyre and brake wear, and even the .e of otherwise mysterious engine and ;mission failure.

a placed the greatest emphasis on chart ysis; with the aid of a device marketed by ograph manufacturers it was shown that iled analysis could give a foot by foot and Ind by second account of a vehicle's prog, the information required when legal eedings followed an accident or, more Ily, a starting point to see where costs

J be cut.

r. Moon gave a brief historical backnd of the instrument from its early begins in Poland in the 1920s to the requireby legislation in Germany in 1952 folig union pressure. By 1970 all goods les over 3,5 tons g.v.w. in Germany will tted with tachographs.

eta ils of various types of instruments were 1, the main difference being in the clock, r the 24-hour type which uses one rding chart, or the eight-day type which eight charts, each changed over autocally by the operation of the clock. The mation recorded was usually time, vehicle and mileage but some instruments also rded engine revolutions. It was possible ave an instrument that would show dart recordings for up to three drivers by of special keys. Efforts by drivers either abotage tachographs or to try to record information would be completely useless. ful analysis of the charts would immedihighlight any attempts at either.

le necessity for having tachograph instalns accurately calibrated to the individual Ile means. said Mr. Moon, fitting would to be done by specialists whose services Id also be required for the annual checkrid calibration of units. The need for this d be gauged by the fact that Keinzle s 555 effectively different sets of adaptor s to give drive-speed accuracy to within per cent.

was stressed that the Keinzle instrument f was accurate to within plus or minus 3 cent on speed recordings and on time rding to within plus or minus 2 min in question came up as to the availability of eh-made instruments; a representative UK manufacturer answered that this ed on the MoT's draft specification which not yet been announced.
