How hot is HOT
As we all no about the heat problems you folks had last summer (E) I thought seems how it's summer here how hot does it really get and Sh%t that V1 does get hot! . I happen to find in my hands a wee laser temperature thermometer. You know like the ones they were sticking in peoples ears at airports when SARS was about a few years ago. Anyway I stuck me V1 in my car window just to see how fast and how hot it got and to my surprise.........
The cars a Mercedes ML 270 (CDI) and was parked up my drive with the window mounted V1 in direct sun light. Before the V1 had been mounted it had a set point temp of 88F top and bottom the cars dash had been in the sun for a while and was 150F! Funny thing was the outside air temperature was only 70F
With no air con the temp was (windows up)
Within 3 mins the V1 had raced to
@ 2 min intervals
T 115 123 130 135 137 140 148
B 109 117 122 129 130 135 141
T 150 151 152 152 152
B 141 142 142 143 143
Turning on the engine and air con turned to full (front window)
within 3 mins
@ 1 min intervals
T 139 136 132 128 124 119 115
B 134 130 123 119 116 111 109
T 113 111 109 107 105 104 103
B 106 104 102 101 99 97 96
T 102 100 97 98 97 96 96
B 95 95 92 92 92 91 91
As you can see with only 70F outside and direct sunlight you can cook your Detector pretty fast So no wounder with the heat you guy's got the poor little V1 couldn't keep cool. I would recommend yall drive with your air con cranking or use a visor mount.
Gentlemen, This is an informative post. Nice work Ghz!
I thought the "E" prob had nothing to do with heating up...............
I think people are confused about VR adding a temp conversion or compensation (I forget the correct wording now) analog to digital. I dont think the "E" has anything to do with actual temp. Although it is not good to let any RD to get really hot. -Just a hunch.
I thought that I heard somewhere that if a V1 displays an E it could be 1 of a thousand things wrong with including but not limited to a temperature problem. Not sure, but when I got an E on my 3.854 (5 total) that is what they said to me.

Ace racer if your V1 is in the window and your getting E's why not try the Visor mount see what happens.
Anyways outside of that I found it very interesting how hot it got and how fast. Also how uniformed the temp was top and bottom when all the sun was directed at the top of the detector, sucks in heat at the top lets it out at the bottom :wink:
Very interesting post GHz1 :wink: The heat would have to play a small part in performance, not unlike radar antennas?
Very nice and informative post, will have to keep this stuff in mind.
Valentine One is capable of handling:
Temperature Range: Operating: -20°C to +70°C (-4°F to +158°F)
Storage: -30°C to +85°C (-22°F to +185°F)
