i.)
Control the correct position of the sensor by lifting up and down the caroussell and
check if the status is indicated correctly by the software.
j.)
Use the same method for the sensor of the lid-caroussell.
k.)
Adjust the speed of the considered caroussell by the particular choke (upper choke:
up; lower choke: down). You reduce speed by closing the choke more and vice
versa.
l.)
The setting of the chokes should be fixed by the lock nut.
m.)

Measurement of grounding conductor resistance
For reasons of safety the check of the grounding conductor resistance is done before delivery.
For measurement of the grounding conductor resistance you need an appropriate electric
measuring instrument. Check all metal surfaces of the instrument.

Programming of Balance, Adjustment of glass chimney
The balance resides inside the TGA (Display: LHS; cable: RHS). The weighing is done by the
pedestal, that reaches the balance at the interior of the analyser. At the scale plate an
adjustable glass tube is assembled, that should reach up to 5 mm to the underside of the lower
heating element. It is important that the height is adjusted correctly.
a.)
The glass tube is build of two parts connected via a ring. To adjust height of the tube
loosen the screw of the ring (LHS) and slide the upper part of the glass tube carefully
upwards.
