Additional functions in the DM4 and DM4 DL Operation
Measuring through coatings:
operating mode DUAL MULTI
With their operating mode DUAL MULTI, DM4 and
DM4 DL offer you the possibility of acurately measur-
ing the metal wall thickness under adherent coatings
(paint coatings, plastic coatings, fiber-reinforced plas-
tic sheathings, etc.).
If such a coating is not taken into account in the wall
thickness measurement, the result may be consider-
able measurement errors depending on the coating
thickness.
The operating mode DUAL MULTI avoids these mea-
surement errors without removing the coating by al-
lowing the measurement between two adjacent
backwall echoes.
H Note:
It is irrelevant for the operating mode DUAL MULTI
wether you choose the DA3 or the AUTO mode.
The following standard probes are suitable for the op-
erating mode DUAL MULTI:
• DA 301 DA 401
• DA 311 DA 411
• DA 312 DA 412
• DA 312 B16
• DA 317
• DA 319
The measuring range of the probes depends on the
type and thickness of the coating, thickness of the
metal, and the quality of the bonding between metal
and coating.
Operation:
– Make sure that the instrument is switched on and
calibrated to the selected probe and material to be
measured (please refer to chapter 5.2 Calibrating
the instrument).
H Note:
You can carry out a 1-point calibration in DUAL MULTI
mode as well if two backwall echoes are measured on
the calibration block. To do this, switch the instrument
