Can MSR Data Loggers be calibrated?Yes ! MSR data loggers have a unique serial number which is a prerequisite for individual calibration. Can the battery be replaced?The battery of an MSR Data Logger is rechargeable rather than disposable. It is re-charged via the USB port every time the logger is connected to the PC. One full charge is sufficient to record data for about 6 months, depending on program and environmental parameters such as interval, frequency of download and environment temperature. Is the software included in the data logger package?Yes ! MSR Data Loggers are delivered ready for use. Every package consists of the data logger, a USB lead and the combined configuration and analysis software. What is a 3-axis accelerometer?Aside from temperature, humidity and pressure the MSR Data Logger is equipped with a 3-axis accelerometer. It registers acceleration resulting from movement of the data logger in x- (backward-forward), y- (left-right) and z-directions (up-down). Taking into account the earth's permanent gravitational pull on the logger it is therefore possible to calculate the unit's actual orientation. What does "internal" and "external" sensors mean?MSR Data Loggers are equipped with sensors for temperature, humidity, pressure and an accelerometer, which are all "internal" sensors, i.e. mounted inside the logger case. Some applications, however, require the use of an "external" sensor to measure parameters more closely to where they occur. It is possible to select external temperature and/or humidity and/or pressure sensors, with an optional lead length of either 15cm, 40cm, 1m or 1.6m. My MSR145 Data Logger indicates temperature values which are far too high.The MSR145 is equipped with an internal re-chargeable battery which heats up during charging. This can lead to an increased temperature indication if an internal sensor is used while the unit is charged. Do I need the temperature sensor if I already have a humidity or pressure sensor?That depends upon your particular measurement requirements. The sensors for relative humidity and pressure each include their own temperature sensor and the temperatures they measure can be evaluated separately. However, the accuracy of the standalone temperature sensor is greater (see the technical specification of the sensors on our product pages). If your results depend upon extremely accurate temperature measurements we recommend that you use the separate temperature sensor. Can MSR measurement data be exported?Yes. Measurement data can be exported in CSV format as a text file. Furthermore, the graphs created by the Viewer software can be saved as image files in BMP and JPG format. You will find the corresponding options in the File menu of the MSR Viewer software. Can measurement data be read out from other applications or from custom programs via USB?Yes. For this purpose software developers can use our free DLLs which allow access to the measurement data. The DLLs together with examples and documentation can be requested from us. How can MSR measurement data be imported into Microsoft Excel?There is an easy solution to opening the CSV files created by the MSR software into Excel correctly.
A new file will open and you should be all set. My question is not listed here ! |
