Calibration; Measurement Procedure; Measuring By Sound Velocity Setting - sauter TD GOLD 40 Instruction Manual

f) To get into the menu selection of the material code, the Material selection key 3-5
has to be pressed. To quit the menu, material selection key has to be pressed again
or it has to be waited until the instrument- after a few seconds- changes back into
measurement mode. On the display appears `0`.

12.5 Calibration

a) 5.1 A little bit contact gel has to be dropped onto the base plate 3-12.
b) The calibration key 3-8 has to be pressed and `CAL` appears on the display.
`CAL` is the abbreviation for calibration.
c) The sensor 3-7 has to be pressed slightly on the base plate. The coupling symbol
((•)) (measurement in action) occurs, if the measuring procedure has been estab-
lished successfully by the process of ultrasound sending and receiving.
On the display appears`5.0mm` or 0.197 inch (debit thickness of the base plate) and
`CAL` in turn.
As soon as the value is stabilized, the `CAL` key 3-8 has to be pressed to confirm.
Then the instrument changes back to the measuring mode.
d) Like this, calibration has been finished and automatically saved in the instrument.

12.6 Measurement procedure

a) The Power key 3-4 has to be pressed to switch on the instrument.
b) The mm/ inch key 3-3 has to be pressed to select the correct measurement unit.
c) The sensor 3-7 has to be placed onto the material surface to be measured,
providing that the material code has been selected correctly.
Assure yourself that coupling is fine and the symbol ((•)) 3-11 is active. The meas-
urement result will be shown on the display.
d) The measurement result is saved until a new measurement is performed. The
last value is conserved on the display until the instrument is switched off.
e) The instrument can be switched off by either by the Power- on/ Power- off key or
by Auto Power off function, one minute after the last key operation.

12.7 Measuring by sound velocity setting

a) By pressing the VEL- key 3-13, the last saved ultrasound velocity is displayed.
b) Measuring of coatings & materials by a known thickness:
