PIERRE, S.D.(KCCR)- Two ballot tabulating machines to be used on election night next week passed a public testing of the devices on Wednesday.

Hughes County Finance Officer Thomas Oliva says test went as expected…very well.

Oliva says the tabulating machines are secured with a number of security measures to indicate possible tampering.

To prevent having to break the seal to start the machine in the event of failure, back-up batteries and generators are on stand-by to keep the machines in working condition on election night.
