The Taser fired at Dalian Atkinson was working properly in tests carried out after the former football star's alleged murder, a court has heard.
PC Benjamin Monk, 42, is accused of using unlawful force by kicking the ex-Aston Villa striker in the head with 'substantial force', while PC Mary Ellen Bettley-Smith, 31, is accused of assaulting him with a baton.
Atkinson, 48, was tasered three times and had two bootlace prints on his forehead after the incident in Telford, Shropshire on August 15, 2016, the court has been told.
He subsequently died of cardio-respiratory arrest in hospital.
PC Monk denies the murder and manslaughter of Mr Atkinson and is on trial at Birmingham Crown Court where proceedings have entered their second week.

Today, an authorised Taser download officer told the jury that data was downloaded from the weapon after its use in Meadow Close, Telford, Shropshire, in August 2016.
The download officer, Sergeant Michael Waterworth, showed jurors the yellow X26 model Taser, held in a clear plastic exhibit bag, while giving evidence at Birmingham Crown Court on Wednesday.
Sgt Waterworth said he carried out tests to ensure that a single press of the trigger produced a standard five-second Taser cycle, and that a safety switch deactivating the weapon was working.
A third test was also conducted by Sgt Waterworth to ensure the Taser's 'extended' cycle - with the trigger pressed for longer than five seconds - was also functioning.
Jurors have heard that Monk is alleged to have fired the Taser at Atkinson three times - with the final deployment lasting 33 seconds.
After Sgt Waterworth described how he had downloaded data from the Taser on to a desktop computer at Shrewsbury police station, Alexandra Healy QC asked him: 'Did the Taser appear to have been operating properly as far as you were concerned?'
The officer replied: 'Yes, it was.'

On the downloaded data, Ms Healy asked: 'Did you notice anything about the length of the activations when you did that download?'
Sgt Waterworth responded: 'Yes, it was a long cycle.'
Asked if the long activation period was something he was used to seeing during a Taser download, the officer said: 'That's very difficult to say.'
Monk, 42, is alleged to have intended to cause really serious injury to Atkinson, who also played for Sheffield Wednesday and Ipswich Town, after two initial uses of a Taser proved ineffective.
Monk's colleague and then partner, Pc Mary Ellen Bettley-Smith, 31, is also facing trial.
She denies a charge of assault occasioning actual bodily harm.
The trial continues.
