The LAP-TEQ PLUS display module shows the horizontal inclination of the top cabinet with a resolution of 0,1° on a dot matrix LCD-display. It powers off after two minutes to save battery power. The calibration function makes it possible to recalibrate the sensor module without having to open the sensor housing. The display module is powered by a lithium polymer battery, which can be charged via USB. The memory function saves the last measured value when the device is switched off. This is displayed in a second row when the device is switched on again, thus helping to compare different line arrays.
