Posted - 05/17/2015 : 01:56:19 Hi all, i´ve registered here,because i´ve a problem with my gmc-300. After carging the battery,i turned on the GMC-300,but the display readings are >ImSV.. I read here in the forum: http://www.gqelectronicsllc.com/forum/topic.asp?TOPIC_ID=4056 that i´ve to calibrate it. I´ve done it.But my µSv readings are now very high,about 0,5µSv/h and rapidly changing.(normally 0,1µSv/h) I can hear a quite clicking,when the GMC-300 is turned on. I measured the voltage with a Fluke multimeter,184V,with an Oscilloscope,around 350V,Oscilloscope+1Gigaohm resistor 408V. Can it be the transformer inside,or is the tube damaged? where can i get this small transformer? hope you can help me... best regards hv freak

Posted - 05/26/2015 : 10:58:48 I´ve done a factory reset,but the readings are very high. It seems that the tube don´t work correct.I´ll trie to change it against a SIG39,which i´ve here. |
