Audiometer Calibration System - Running a Test - Model AudCal

[@torrrock1788]

Dear Sirs. The video is great, but it is possible to see a video of the 824 model .... I have the old model, I need to do a cabin measurement and I can't download the timer measurement. Please could you help me with that function however on your website there is no video or even an explanation of how to use the mode manual.
