The amount of mounting medium selected works fine sometimes but at other times it does not – what is the problem? FAQ Report A:Different amounts of medium may be required at different times of the day The viscosity of mounting media is temperature-dependent. As a rule of thumb, the viscosity of the medium becomes lower when ambient temperature rises. You may need to change the general settings (e.g. reduce volume, type, nozzle size) at certain times of each day, if you experience such problems. We recommend reading the operator’s manual first. There are several options to de- and increase the volume, type (pressure) and/or the installation of a nozzle with a larger diameter.
