Page 3: Introduction
1 Introduction 1.1 MSE The MSE series colorimeter offers a unique combination of high speed and accurate colour measurement capabilities packed in a robust jacket. The MSE colorimeter is available in 10mm spot size and M8 fibre connector version. The fibre version is available with several optics, custom optics can be applied on request. -

Page 6: Trigger In/Out
2.3 Trigger in/out 2.4 Power connections The MSE has two trigger connections. One trigger output and one trigger The MSE should be connected to USB with enough supply or using a 9V input (SMA connectors). The MSE can be triggered when it is operating in DC power supply to the RS232 connector. -
Page 7: Communications Protocol
When the MSE colorimeter is connected to the host, it will start the MSE colorimeter firmware. As soon as the firmware is idle to receive commands, the Power LED goes to the on state. The Admesy bootloader is a RAW USB device and in order to use this device in Windows, a driver must be installed which is supplied by Admesy. -

Page 17: Auto-Ranging
7 Auto-ranging 7.1 Introduction 7.2 How auto-ranging works The MSE includes an auto-range function. This function is useful in case The auto-ranging works, by first setting a default integration time. If this the measured object shows an unknown luminance value. In this case, the already meets the criteria for a good measurement, the measurement will MSE will try to find the optimum setting which is a trade-off between speed be done using that integration time. -

For this test, a 20” TFT display (standard desktop the adjmax level. The latter one is fixed by Admesy. LCD) was used with black at 0.2 cd/m² and white at 187 cd/m² and a frame ... - Page 19 The test patterns consist of two sets, each containing 24 colours: The results of auto-ranging show a stability level of approximately +-0.001 on color. A higher adjmin level will logically improve this, though it Unsaturated set (figure 6) increases the total measurement time. Note that the wait time after setting ...

Page 21: Auto-Ranging Recommendations
7.6 Auto-ranging recommendations It is recommended to apply auto-ranging in case process variation is high or in case various grey scales are measured. In cases where luminance settings are know, it may be desirable to turn off auto-ranging to save additional measurement / test time. -
