TECHNICAL REFERENCE MANUAL
1.4 Measuring range
The DLS-C(H)/FLS-C(H) is an optical instrument, whose operation is influenced by environmental conditions. Therefore, the measuring range
achieved in use may vary. The following conditions may influence the measuring range:
Key Factors increasing range Factors reducing range
Target surface Bright and reflective surfaces such as the target plates
(See Accessories)
Matt and dark surfaces
Green and blue surfaces
Airborne particles Clean air Dust, fog, heavy rainfall, heavy snowfall
Sunshine Darkness Bright sunshine on the target
The measurement range may be influenced by configuring different measurement modes. See 8.3.2 Enhanced measuring Modes (sNuc) on
page 25.
The DLS-C(H)/FLS-C(H) does not compensate the influence of the atmospheric environment, which may be relevant when measuring long
distances (e.g. > 150m). These effects are described in:
B.Edlen: “The Refractive Index of Air, Metrologia 2”, 71-80 (1966)
1.5 Prevention of erroneous measurements
1.5.1 Rough surfaces
On a rough surface (e.g. coarse plaster), measure against the center of the illuminated area. To avoid measuring to the bottom of gaps in the
surface use a target plate (see accessories) or board.
1.5.2 Transparent surfaces
To avoid measuring errors, do not measure against transparent surfaces such as colorless liquids (such as water) or (dust-free) glass. In case of
unfamiliar materials and liquids, always carry out a trial measurement.
)Erroneous measurements can occur when aiming through glass panes
or if there are several objects in the line of sight.
1.5.3 Wet, smooth, or high-gloss surfaces
1 Aiming at an “acute“ angle deflects the laser beam. The DLS-C(H)/FLS-C(H) may receive a signal that is
too weak (error message 255) or it may measure the distance targeted by the deflected laser beam.
2 If aiming at a right angle, the DLS-C(H)/FLS-C(H) may receive a signal that is too strong (error message 256).
1.5.4 Inclined, round surfaces
Measurement is possible as long as there is enough target surface area for the laser spot. On irregular and round surfaces the arithmetic
average of the illuminated surfaces will be measured.
1.5.5 Multiple reflections
Erroneous measurements may occur if the laser beam is reflected by other objects than the target. Avoid any reflective object along the
measurement path.

TECHNICAL REFERENCE MANUAL
2 Device setup
We recommend that you carry out the configuration steps in an office before mounting the device, especially if you are not familiar with the
DLS-C(H)/FLS-C(H).
The DLS-C(H)/FLS-C(H) supports two types of operating modes:
•Controlled mode (Host controlled)
•Automatic mode (for use in stand-alone operation)
The first decision to be taken is the type of operating mode that will be used to transmit the distance measurement data. While the
controlled mode provides maximum flexibility and accuracy, it is often not suitable for integration into existing PLCs or analog environments.
In such cases the automatic mode might be preferred.
Influence factors controlled mode automatic mode
(with analog and/or digital outputs)
Accuracy Maximum measurement accuracy Accuracy depends on signal scaling
(see 8.3.6 Set/Get distance range (sNv) on page 27)
Flexibility Access to full command set Limited
Integration Requires protocol implementation Wiring of AO and/or DO signals
Connection Connection of up to 10 DLS-C(H)/FLS-C(H)s to a
single RS-422 line.
Point-to-point connection
The following two sections describe the configuration of the DLS-C(H)/FLS-C(H) for the controlled and automatic modes.
2.1 Connection
To be able to configure the DLS-C(H)/FLS-C(H), it must be powered and connected to a PC. Figure 2 shows the necessary connections. On the
PC, any terminal program can be used to communicate with the module. A configuration utility is also available on the web page
www.dimetix.com.

TECHNICAL REFERENCE MANUAL
2.4 Display Mode
If Display Mode is enabled, the DLS-C(H)/FLS-C(H) formats the measured
distance as ASCII string, which is understood by External Displays with a
serial interface. Since the DLS-C(H)/FLS-C(H) outputs this formatted string
automatically on the serial interface after completing a measurement.
Measurement results can be displayed on an external display without an
additional controller.
For a detailed description of this mode, please contact Dimetix or your
dealer.
2.5 External Trigger
The DLS-C(H)/FLS-C(H) includes the option of triggering measurements

ground (AGND).
Make sure, that the total resistance in the analog path is lower than 500
3.3 Alignment of the laser beam
Alignment of the laser beam is often difficult when the target is far away, as the laser spot is not visible. An optional telescopic viewfinder is
available which simplifies the alignment significantly.

4.1 Measuring accuracy
The measuring accuracy corresponds to the ISO-recommendation ISO/R 1938-1971 with a
statistical confidence level of 95.4% (i.e. ± twice the standard deviation σ,refer to
diagram on the right). The typical measuring accuracy relates to average conditions for
measuring. It is ±1.0mm for the FLS-C(H) 10, ±1.5mm for the DLS-C(H) 15 and ± 3.0mm
for the DLS-C(H)/FLS-C(H) 30 valid in the tracking mode.
Maximum deviation may occur under unfavorable conditions such as bright sunlight or
when measuring to poorly reflecting or very rough surfaces. Measuring accuracy may
deteriorate by approximately ±0.02mm/m for distances above 30m.
The DLS-C(H)/FLS-C(H) does not compensate changes of atmospheric environment. These
changes can influence the accuracy if measuring long distances (>150m) under conditions
very different from 20°C, 60% relative humidity and 953 mbar air pressure. The influences
of the atmospheric environment are described in
