The degree fraction figures are highlighted.
4. Turn the control to select the desired fraction of a degree.
5. Press the control to accept the value.
Connecting to tap water
When using tap water:
1. Make sure the tap water is conveniently located near the TGA 4000.
2. Connect one hose to the Cooling Liquid In tube. Place a hose clamp around the hose
and tube to secure the hose in place.
3. Connect the other end of this hose to the tap.
4. Connect the other hose to the Cooling Liquid Out tube. Place a hose clamp around the
hose and tube to secure the hose in place.
5. Connect the other end of the hose to a suitable drain.
The temperature of the cooling liquid should not change more then 0.4 °C/hour in the case
of tap water.
CAUTION
ATTENTION
The heat exchanger of the TGA 4000 will NOT accept pressure.
Therefore, flow regulation should be done before the water enters the
TGA 4000.
L'échangeur de chaleur du TGA 4000 n'acceptera PAS la pression. Par
conséquent, la régulation du débit devrait être effectuée avant que l'eau
entre dans le TGA 4000.
CAUTION
ATTENTION
It is essential to maintain a very constant flow rate of approximately 5
l/h (80–90 ml/min). The liquid should be free of air bubbles. Changes in
the liquid flow rate or the presence of air bubbles will negatively
influence the quality of the measurement signal.
Il est essentiel de maintenir un débit très constant d'environ 5 l/h (80-90
ml/min). Le liquide doit être exempt de bulles d'air. Les changements
dans le débit de liquide ou la présence de bulles d'air influenceront
négativement la qualité du signal de mesure.
