For correct analysis results it is important to avoid rubbing of the balance pedestal at the
borders of the notch at the lower heating element.
b.)
To arrange the pedestal at the notch loosen the screw at the upper left edge of the
board and hinge it down (RHS).
c.)
At the underside of the balance there are two adjustable feet, that can be turned
simultanously to move the pedestal at the right position.
For the weighing and effective analysis it is necessary to program the balance. For
programming of the balance please read operation manual of the balance. The required
allocations for the use of the balance at Thermostep are:
1.1.4
unstable surroundings
5.1.7
9600 Baud
6.1.3
auto sense stability
1.7
Control of voltages
Required tools:
voltage measuring device
These are the different supply voltages of the controller of the analyser. These are shown at
form
Status
and support the following components:
24 V: supply voltage of the board
18 V: supply voltage of the balance
(not measurable)
12 V: supply voltage of the board
