The Russian MP gauge measures in mmHg (torr) which is conveniently 3/4 (0.7500615 to be pedantic) of your (UK) altimeter millibar reading ... i.e. 1000mb equates to 750mmHg. Easiest way to calculate this is to take 3/4 of ambient pressure variation from 1000mb and factor this against 750mmHg ... so 1020mb => 3/4 x (1020mb - 1000mb) = 15mmHg + 750mHg = 765mmHg The manifold gauge is only marked in 20mmHg divisions so this will not give a particularly accurate reading ... especially as its probably never been re-calibrated since manufacture. However it should be good enough to ascertain whether the MP gauge is working or not to help with your fault finding. FYI ... on my 52 the MP gauge reads 10mmHg low against the altimeter reading. Hope this helps.

But when installed, it sometimes works, sometimes does not. I discovered that I only have 3 volts on the supply wire when switching on the "radio" button on the front panel. First I thought it was the battery, but I checked it, and it's in perfect shape. One of the symptoms : I hear some "clicking" or "ticking" in the headset, and usually after 3 to 4 minutes, it switches on. As if one or another relay tries to switch on ? It's definitely not the new radio, since I am using a provisional bypass, connecting it immediately to the battery - until the problem is solved. The problem is not introduced with the new radio either, since with the old radio, I had the same problem. This is the reason why I was forced to replace the old radio (thinking it was dead). Any idea ? Best regards, Jan Mevis Yak 50 RA2005K
