Page 20: Settings Menu
Settings Menu Time/Date When saving data, the meter uses time and date for the filename and the point in time at which the measurement was performed. If time is not set by the user, time and date begin with the factory setting after inserting the battery, and is then used for data storage. -
Page 21: Measuring Menu
Automatic Shutdown The meter is shut down automatically if no keys are pressed during the specified time period in order to save energy. All measured values and settings are saved and retained until the meter is switched back on again by pressing the key. -
Page 22: Storage Menu
Storage Menu All of the settings in this menu are related to the memory mode. In order for the CSV file to be read in correctly by country-specific software applications, the time format, the date format and the decimal separator may need to be adjusted. Log Interval The log interval can be set in HH:MM:SS and specifies the time interval at which measured values are written to the file during data logger operation. -
Page 23: Information Menu
Information Menu Important device information is summarized in this menu. This includes serial number, the hardware and firmware versions of the MAVOMASTER and the connected MAVOPROBE, and the MAVOMASTER’s temperature and battery voltage level. -
Page 24: Measuring Functions
Measuring Functions The user can assign various measuring functions to the F1 and F2 function keys under Settings in the Measuring menu, which appear in the display above the key as a label. Briefly pressing the function key activates the respective measuring function, and briefly pressing it once again deactivates the measuring function. -
Page 25: Int - Integral
INT – Integral The INT measuring function is used to determine the irradiation dose and integrates irradiance over time. The INT measuring function is activated by briefly pressing the assigned function key. Irradiation dose then appears at the upper display and integration time at the lower display. The INT measuring function is terminated by briefly pressing the assigned function key and a prompt is displayed asking whether the function values should be saved or discarded. -

B/A – Ratio The B/A measuring function is used for contrast measurement or to determine workplace luminance distribution. Reference value A can be frozen by pressing the HOLD key. After briefly pressing the assigned function key, the B/A measuring function is activated and the measured or frozen measured value is saved as reference value A. -
Page 28: A - Percentage Deviation
%A – Percentage Deviation Measuring function %A can be used to assess the uniformity of monitor screens, uniform illumination of projection surfaces and uniform lighting of workplaces. The value obtained at the center is usually used as reference value A. Reference value A can be frozen by pressing the HOLD key. After briefly pressing the assigned function key, the %A measuring function is activated and the measured or frozen measured value is saved as reference value A. -
Page 29: B-A - Relative Deviation
B-A – Relative Deviation Measuring function B-A can be used to determine deviation. The value obtained from the reference part is usually used as reference value A. Reference value A can be frozen by pressing the HOLD key. After briefly pressing the assigned function key, the B-A measuring function is activated and the measured or frozen measured value is saved as reference value A. -
Page 30: Log - Data Logger
LOG – Data Logger Measured values are saved at the log interval specified under Settings in the Storage menu in the LOG measuring function. A brief acoustic signal confirms each storage operation. The measuring function or the meter can only be switched off as long as the data logger is active. When the measuring function is ended, recording is stopped and the measured value file is closed. -
Page 31: Peak - Extreme Values, Mean Value
PEAK – Extreme Values, Mean Value The PEAK function acquires the largest value (MAX), the smallest value (MIN) and the arithmetic mean value (AVG) in the background during measurement. MAX, MIN and AVG values are displayed successively by briefly pressing the PEAK key repeatedly. If no further operation takes place during the PEAK display, the PEAK display is automatically exited. -
Page 32: Memory Functions
Memory Functions In addition to a display memory, the MAVOMASTER is also equipped with an 8 GB measured value memory. This makes it possible to record several measurements on site, and to read them out and evaluate them at a later point in time. Stored values are retained when the instrument is switched off, as well as when the batteries are replaced. -
Page 33: Saving Function Values
Saving Function Values A separate filename is assigned to each measuring function, which is laid out as described in section 7.2. When the measuring function is exited, a prompt appears asking the user whether or not the function values should be saved. If “Yes” is selected, a measured value file is saved to the daily folder. Storage is acknowledged by an acoustic signal and “saved”... -
