Compact Measuring and Display Device with a Diverse Range of Functions

The compact MAVOMASTER measuring and display device includes a high-contrast graphic display with adjustable background illumination for displaying the various measured values obtained by the connected measuring probe along with their units of measure, or quantities calculated from these values. The basic meter also serves as power supply, display, control unit, and data storage module – all in one. Its data can be read out via the USB interface, via which the meter can also be controlled. When plugged into a computer, the MAVOMASTER functions like an external drive.

Functions and Features:

• NORMAL MEASUREMENT – continuous measurement and display of absolute measured quantities.
• INDIVIDUALIZED CONFIGURATION – available measuring functions can be freely assigned to the F1 and F2 function keys.
• RELATIVE MEASUREMENT – continuous measurement and display of absolute measured quantity(ies) / reference value(s) when the measuring mode is started.
• INTEGRAL MEASUREMENT – integration of the measured quantity over time, display of the integral value as well as the time elapsed since activation – determination of the irradiation dose.
• RASTER MEASUREMENT – storage of individual measurement points and continuous calculation of mean, minimum, and maximum values, as well as uniformity and non-uniformity – workplace illumination.
• B/A RATIO MEASUREMENT – continuous calculation of the ratio of the measured value to the reference value when the measuring function is started – contrast measurement, luminance distribution.
• B-A DEVIATION MEASUREMENT – continuous calculation of the relative deviation of the measured value from the reference value when the measuring function is started – matching of luminance values and lighting.
• %A DEVIATION MEASUREMENT – continuous calculation of percentage deviation of the measured value from the reference value when the measuring function is started – uniformity of luminance and illumination.
• DATA LOGGER – continuous recording of measured quantity time curves. Measurement data are written to a data file at adjustable time intervals.
• PEAK – acquisition of minimum, maximum, and mean values.
• HOLD – freezes the measured value display.
• MEM – storage and deletion of individual measured values.
• LARGE MEASURED VALUE MEMORY – 8 GB, readable via USB, functions like an external drive.

Newly developed from the ground up, MAVOMASTER and MAVOPROBES elevate light metering and certification to an entirely new level: a universal, basic MAVOMASTER meter can now be easily and flexibly combined with a diverse range of MAVOPROBES (measuring probes). For example with classified measuring probes for illuminance in accordance with DIN 5032-7 class B or C, luminance in accordance with DIN 5032-7 class B or with a UV-A/LUX combination probe for non-destructive testing – for efficient light testing and certification in a great variety of applications.

Each MAVOPROBE is balanced prior to shipment and can be connected immediately to any MAVOMASTER. The classified MAVOPROBES transmit acquired measurement data to the MAVOMASTER in digital format. Furthermore, it’s also possible to connect the measuring probes directly to a computer using an optional USB adapter cable. A single to multi-channel measuring system can thus be implemented with the measuring probes. The measuring probes can also be consolidated using a USB hub and supplied with voltage from a power pack. The open interface protocol makes it simple and easy to integrate the measuring probes into your own applications. The firmware for all of the probes and the basic meter is updated via the USB interface. The system concept also offers advantages for calibration because the measuring probes can be calibrated separately – for simplified shipping and reduced downtime.

The intelligent components of our light metering system open up new possibilities – whether a stand-alone measuring instrument is required or when setting up single or multi-channel measuring systems. Various measuring requirements specified in the fields of photometry and radiometry are covered by the individual MAVOPROBE measuring probes. All of the intelligence required for the processing of measured values is now located in the probe, thus permitting universal use and separate calibration.

Each probe can be used with a MAVOMASTER as a stand-alone measuring instrument. The probes can also be used cost-effectively in single or multi-channel measuring systems with an optional USB adapter.

With optional 3, 5, and 10 m measuring probes extension cords.
