CT-2000 Instruction Manual
Caution: The bath must be placed in its intended final position before adding
bath fluid. Never move the CT-2000 when filled with bath fluid.
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. Refer to Appendix II: Choosing a Temperature Bath Liquid.
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. Refer to Figure 16.
Figure 16: Filling the Bath
3. Continue to add fluid until the bath liquid level has risen to within 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 to 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 fluids expand at different rates. Be careful not to overfill
the bath.
