the measuring head: Move the measuring slide upward until the stop; exert a force on
the handwheel, like if you would do a probing up; this will lock the transport carriage on the
measuring carriage. To unlock the carriage do the same, but in the opposite direction.

The TESA-Hite 400 / 700 is powered by a 6V rechargeable battery (N° 00760157). This is recharged
using the mains adapter N° 04761054 and the cable EU N° 04761055 or US N° 04761056
(see chapter 7.2 – Charging the battery).

Measuring system
The TESA-Hite Magna 400 / 700 incorporates the magnetic measuring system magna
µ
system which
digitally records the measured dimension, called the mesurande (TESA patent). From point A, the
reading system can be moved downwards to the respective trigger points. Once one of these points
has been reached, the reading of the value is triggered, that is to say that the position of the
measuring head in relation to the magnetic scale is read off by the sensor. The distance C,
symmetrical in relation to the position of each trigger point in the travel of the measuring system is
kept for seeking the culminating point when probing cylindrical surfaces. (Read section 4.7 also).

It is agreed that a perfectly accurate measuring instrument is impossible to produce. Therefore, the
value indicated by any instrument comprises a deviation from the true value; this deviation is
composed of the bias errors and the random errors. Random errors cannot be predicted since they
are the result of influences that cannot be controlled, e.g. the value dispersion. Bias errors, on the
other hand, as for example the deviations of the scale divisions on the material measure or the form
and positional errors of the measuring head guides can be corrected once they have been measured.
To correct length measurements, after the TESA-Hite Magna 400 / 700 has been completely
assembled; the actual errors are determined step-by-step by means of a system of stepped gauge
