Filling the Bath
Make sure that the bath is placed in its intended final position before adding bath fluid. The CT-500
should not be moved with bath fluid in the bath jar.
Warning: Never use flammable bath liquids.
1. Make sure that the instrument power is OFF and select a bath liquid appropriate to your
operating temperature range (see
Appendix II – Choosing a Temperature Bath Fluid
).
2. Fill the jar with bath liquid at ambient temperature to a level sufficient to engage the float
switch. This float permits bath operation when the minimum amount of fluid has been added to
the bath jar.
3. Continue to add fluid until the bath liquid level has risen to approximately 40 mm (1.5") of the
top of the jar.
4. Turn the instrument power ON and incrementally heat the bath to desired control temperature
while monitoring the bath liquid level carefully. The bath level must be 15 mm - 20 mm
(approximately ½" to ¾") from the top of the jar at the control temperature. If it becomes
apparent that this liquid level will not be achieved, return the bath to within 10 °C of ambient,
turn the instrument power OFF and add or remove liquid as necessary.
5. Repeat step four until you have attained the proper bath liquid level at the desired control
temperature.
Caution:
Different bath liquids expand at different rates. Do not overfill the
bath.
Warning: Monitor the level of bath liquid closely when operating the CT-500 at
higher temperatures (80 °C to 100 °C). The bath liquid expands as the
temperature increases. The CT-500 bath jar is not designed to contain liquid
under pressure. If the bath is overfilled it may overflow.
