1-4 Issue 05, 01/01 Krautkramer DM4E / DM4 / DM4 DL
Introduction DM4E, DM4 and DM4 DL
Special features of all three versions
(DM4E, DM4, DM4 DL):
• Automatic probe recognition; with DIALOG probes
optimum setting and performance of the instrument;
especially for a higher measurement accuracy by
individually stored correction data in the probe
• Automatic probe zero for quick calibration
• Automatic V-path correction for measurement
linearity over the complete measurement range
• Digital resolution of 0.01 mm (for thicknesses up to
99.99 mm) and 0.1 mm (for thicknesses > 99.99 mm)
• MIN mode with increased pulse repetition frequency
for detection of the smallest measurement value
• Up to 200 hours operation with AlMn batteries
• Automatic gain adjustment
• Large, easy to read digital display with switchable
backlight
• Lightweight, ergonomic and rugged housing
Extended functions for DM4 and DM4 DL:
• Operating mode DUAL MULTI - measurement
through coatings
• Manual gain adjustment
• Programmable minimum and maximum limits with
LED alarm
• Difference mode for comparing the measured
thickness with a variable nominal value
Special features of the DM4 DL (Data Logger):
• Integrated Data Logger with a capacity for 5390
values which can be divided into 999 files
• Access to the individual measurement values and
files (viewing, editing and deleting),
• RS 232 interface for data transfer to a printer or PC
(with special software)
