10. No signal possible LED Failure O Qn E GM Light parameter 3012 is a signal strength detected by the T Guard internal sensor going from a range of about 100 noise level to 4000 You can interpret it approximately as follows e 0 to 300 no probe is detected Temperature reading is rejected e 300 to 1000 a probe is present but exhibits a weak signal This corresponds to a power level ranging from 0 to 10 Temperature reading is rejected e 1000 to 3100 a good probe is present the higher the power the more healthy the probe The power will be more than 10 here e 3100 to 4000 probe saturation Electronic problems Tdecay parameter This is given for information only It gives no information regarding the performance of the probe To summarize a very good probe is characterized by a good power indicator gt 2500 and by a small LED intensity lt 3000 Also dirty connectors will contribute to lower probe strength always insure that all fiber connections are clean before evaluating probe performance Warning After a power on or after changing or exchanging probes or extension cords allow sufficient time for the T Guard optimization process to complete before invoking the y command it most cases it may take as much as 1 minute for this optimization to complete 5 4 Typical temperature reading sequence Once all parameters have been set the following sequence should normally be followed to extract temperature informat
