Introduction
The TNT 12000 is a calibrated instrument. Fluke Biomedical recommends a calibration
period of one year. To help make sure the TNT 12000 stay in calibration, prevent
mechanical abuse during operation and storage.
W Caution
To prevent damage to the TNT 12000, always operate the TNT
12000 in the specified operation temperature range and
humidity in the specifications.
Ion Chamber Care
When the ion chamber is not connected to a cable, put the dust cap on the connector.
The dust cap helps keep contaminates out of the connector, decrease damage to the
connector, and assures a long service life without electrical leakage.
Install the dust cap on the Dosimeter Detector input connector when it is not connected to
an ion chamber.

Clean the TNT 12000 external surfaces with a damp cloth and weak detergent.
W Caution
To prevent damage to the TNT 12000 or an unwanted effect on
performance, do not apply liquids as a spray or put in liquids.
