(b) The envelope shall not be opened until at least one inspector of election from each of the political parties is present at the polling place and shall have examined the envelope to see that it has not been opened. Prior to opening the envelope, all election officials present shall examine the number on the seal on the machine and the number registered on the protective counter to see if they are the same as the corresponding numbers on the envelope.

(c) In the event that they are not the same, the machine shall not be opened until the custodian shall be re-examined the machine and certified that it is properly arranged.

(d) In the event that the numbers on the seal and protective counters are found to correspond with the numbers on the envelope, the election officials shall carefully examine every counter and see that it registers zero.

(e) In the event that any counter is found not to register zero, that machine shall be disqualified from use until the designated election officials have determined and certified that the machine in question has been fully tested and rendered operational and in compliance with all election statutes guaranteeing the accuracy of the machines.

(f) The machine or device shall remain locked against voting until the polls are formally opened and shall not thereafter be operated except by voters in voting.
