Calibration Procedure - KM820/V

Verifying Infra-Red Non contact thermometers

• Insert the reference thermometer probe (e.g.

KM20Ref) fully into one of the holes in the Validator.

• Allow the instruments to stabilise to environment

conditions.

• Switch on both instruments after stabilisation

period.

• Point the Infra-Red thermometer at the base of the

Validator while ensuring the nozzle is as far inside

the Validator cup as is possible. Note the variation.

(acceptable error 2.5°C)

Verifying Contact Thermometers

• Insert the reference thermometer probe (e.g.

KM20Ref) fully into one of the holes in the Validator.

• Insert the probe of the Instrument being veried

fully into the other hole in the Validator.

• Allow the instruments to stabilise to environment

conditions.

• Switch on both instruments after stabilisation

period.

• Note the variation. The acceptance error will be

dependent on the specication of the unit being

veried.

Note: The time for the instruments to stabilise will be dependent on

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.
