The weight deviation in the upper range on our HI 2151/30WC has been growing slowly over the last couple of months. I noticed that the status LED's for Alarm 1 + 2 were blinking alternatively with the LED's for 'Zero Track' + 'Motion' + 'CTR Zero'. The weight reading on the display was normal. After switching the module off and on the LED's were still blinking. Measurement of Excitation, Sense and Signal wires gave normal results. The unit was switched off and on once again, after which the LED's were not blinking anymore. Could you give me an explanation for the blinking LED's? Could this also cause a weight deviation?
