Switch on both instruments after stabilisation
period.

Validator while ensuring the nozzle is as far inside
the Validator cup as is possible. Note the variation.

KM20Ref) fully into one of the holes in the Validator.
•
Insert the probe of the Instrument being verified
fully into the other hole in the Validator.
•
Allow the instruments to stabilise to environment
conditions.

Note the variation. The acceptance error will be
dependent on the specification of the unit being

the validator reaching its environment temperature, which at freezer
temperatures could be up to 2 hours.
Care must be exercised when handling the validator after
exposure to low temperatures.
