Maintaining the Instrument
The primary maintenance procedures described in this section are the customer’s responsibility. Any fur-
ther maintenance should be performed by a representative of TA Instruments or other qualified service per-
sonnel. Consult TRIOS software Online Help for further information.
CAUTION: Before using any cleaning or decontamination method except those recommended by
TA Instruments, check with TA Instruments that the proposed method will not damage the instru-
ment.
MISE EN GARDE: Avant d'utiliser une méthode de nettoyage ou de décontamination autre que
celle recommandée par TA Instruments, vérifiez auprès de TA Instruments que la méthode proposée
n'endommagera pas l'instrument.
Conditioning the Balance
Balance conditioning is required for the Discovery TGA in order to achieve optimum performance from
your instrument and keep the balance housing dry. Perform a balance conditioning when the instrument is
first installed and whenever the balance housing is opened.
In order to ensure an inert atmosphere, the balance housing will need to be flushed of air. This could take
up to 12 hours.
To maintain a dry balance after conditioning, use a balance purge rate of 10 mL/min for an IR and EGA
furnace or 40 mL/min for a wire-wound furnace.
Cleaning the Furnace
After extended use, the inside of the furnace may become coated with sample and therefore require clean-
ing. Periodic cleaning is recommended for optimum operation and performance.
See TRIOS software Online Help for furnace cleaning instructions.
DANGER: Because of the high power circuitry in this instrument, untrained personnel must not
attempt to test or repair any electrical circuits.
DANGER: À cause de la présence de circuits électriques de grande puissance dans cet instru-
ment, le personnel non formé ne doit pas essayer de tester ou de réparer les circuits élec-
triques.
