Hi, I'm Gao from China! I have bought your GHL machines. There is a bug when I plug the PL-1258 in the P3/P4 host of GHL or the first and second generation of expander, the temperature showed on the hosts or expanders is normal, but the temperature shows by the probe plugged in the PL-1258 is not correct. For example, if the probe plugged in the hosts or expanders increases two degree centigrade, the probe in the PL-1258 will show the temperature decreased by the same two degree centigrade, I think it's the software bug not the hardware problems, because I tested on the P3/P4 hosts and first/second generation of expander, it showed the same problem, only the probe on PL-1258 goes wrong. Please check how can I solve this problem! Thanks and best regards!
