I would check the pulse and analog HV values. If they reached ~ 1800V and 3300V accordingly, you will need to replace the EM detector. If EM tune fails but your calibration is fine, you can still measure. You just need to be sure that EM is replaced soon, if the thresholds are reached for pulse and analog regions.
