Basic safety instructions Intended use The Cube M is used to measure power in the beam path of lasers. Please observe and adhere to the specifications and limit values given in chapter 15, „Technical data“, on page 30. Other forms of usage are improper. The information contained in this oper- ating manual must be strictly observed to ensure proper use of the device.

Cube M • Depending on the laser source, it may be necessary to wear suitable protective clothing or protective gloves. • Please protect yourself from direct laser radiation, scattered radiation as well as from beams generated from laser radiation (e.g. by using appropriate shielding walls or by weakening the radiation to a harmless level).
Cube M Symbol explanation The following symbols and signal words indicate possible residual risks: DANGER means that death or serious physical injuries will occur if necessary safety precautions are not taken. WARNING means that death or serious physical injuries can occur if necessary safety precautions are not taken.
Cube M Further symbols that are not safety-related: Here you can find useful information and helpful hints. With the CE marking the manufacturer guarantees that his product is in confor- mity with the EC guidelines. Call for observing (visual feedback from the device or the software).
Display On/Off button Micro-USB socket Fig. 5.1: System description of the Cube M Measuring principles The absorber of the calorimetric measurement system is irradiated by a laser for a short period of time. The temperature difference of the absorber between start and finish of the laser pulse is measured.
Cube M Installation/Removal Prepare installation Turn off the laser source. Ensure that moving parts, e.g. robot arms, etc. are at a standstill and that they cannot be set in motion unintentionally. DANGER Serious eye or skin injury due to laser radiation...
„Technical data“, page 30. The Cube M is positioned above the focus (see Fig. 7.1 on page 12). Make sure that the laser beam is convergent and the permissible power density at beam entrance is not exceeded.
The alignment tool is made of plastic. The exposure with laser radiation will destroy the alignment tool. X Remove the alignment tool before measurement. Marking Alignment tool Fig. 7.2: Alignment of the Cube M using the alignment tool Revision 05/2018 EN...
The device must not be able to move. Connect the interlock connection cable. Remove the alignment tool from the protective window of the device. Fig. 7.3: Mounting threads in the Cube M housing Remove the Cube M Turn off the laser source.
Cube M Connections Laser interlock Micro-USB socket Fig. 8.1: Connections External safety circuit (Laser interlock) The external safety circuit protects the measuring device from damages caused by switching of the laser in case of an error. If the absorber is still too hot, pin 3 and 4 are connected. If the absorber is ready for operation, pin 1 and 4 are connected.
1 Bluetooth stick, the range under free space conditions is approx. 100 m. After switching on the device, the Bluetooth connection is permanently active. The Cube M can be controlled entirely via the Bluetooth connection, and it is also pos- sible to transmit the measuring values. When the Bluetooth connection is activated, the USB interface is deactivated.

Cube M 10.1 Status messages Status message Meaning Waiting for laser beam The device is ready for operation, the laser can be turned on. Check temp. The temperature gradient (change in the absorber temperature/time) is checked. Please wait until the message disappears. Thereafter, the device is ready to measure again.
Cube M Measuring and displaying with the Cube M 11.1 Safety instructions DANGER Severe eye or skin injury due to laser radiation During the measurement the laser beam is guided on the device, which causes scattered or directed reflection of the laser beam (laser class 4).
Cube M 11.2 Laser parameter setting 11.2.1 Setting the laser rise time The applicable measurement time is between 0.1 s and 2.0 s, which has to be trans- ferred to the laser controller as pulse length. The maximum laser rise time for measuring the power cannot exceed 100 µs.
Cube M 11.2.2 Minimum energy per single measurement The energy used for the measurement must achieve a sufficiently high temperature in the absorber to be recorded with high precision. Energy of about 300 J is generally recommended, as long as the measurement duration is < 2 s.
Cube M 11.3 Single measurement Please read chapter 11.1, „Safety instructions“, on page 19 first. Press the on/off button for at least 5 seconds. The start menu appears. After approx. 5 seconds, the device is ready for operation. Turn on the laser. For a high measurement accuracy, we recommend an energy input of 300 J per measurement.
Cube M 11.4 Serial measurement Please read chapter 11.1, „Safety instructions“, on page 19 first. Always start a measurement series with the smallest power and increase it gradually. Small amounts of energy should be measured with absorber temperatures that are close to the ambient temperature.
11.6 Reading off measuring values The last 14 measuring values can be read off from the display of The Cube M. You can read off the last 30 measuring values with the optional Android™ PRIMES Cube App for mobile devices or optional LaserDiagnosticsSoftware LDS.
12.2 Measurement and evaluation with the PRIMES Cube App With the PRIMES Cube app (not included in delivery) for mobile devices with Android™ you can operate and evaluate the device via a smartphone/tablet. The PRIMES Cube App is available in the Google Play Store/Tools. The functions can be found in Tab.
The operator is responsible for determining the maintenance intervals for the measuring device. PRIMES recommends a maintenance interval of 12 months for inspection and validation or calibration. If the device is used only sporadically, the maintenance interval can also be extended up to 24 months.
