Maintenance and repair of the TE-1500 Applications The TE-1500 is designed to be used for precise kinematic viscosity measurements between the temperatures of +10°C and -30°C. Because of its temperature stability and ease of use, it is also suitable for use in other applications where temperatures must be maintained within close tolerances.
Assorted hoses, tubes, and connecting cables Temperature selection A selector dial on the front panel of the TE-1500 Control Chassis permits convenient temperature selection at 10, 0, -5, -10, -15, -20, -25, and -30°C for kinematic viscosity measurement. After the dial has been set, the bath will equilibrate at or near the desired temperature.
All technicians who use the TE-1500 should follow these basic safety procedures: Do not place the TE-1500 system on an unstable cart or stand. The TE-1500 should be placed on a stable laboratory table or bench. Keep the TE-1500 away from tubs, sinks, or other water vessels. If...

Do not attempt to service to TE-1500 system by removing panels and trying to effect repairs. Contact CANNON ® Instrument Company for all service and repair needs. Use a bath fluid appropriate for the desired test temperature and operational environment. Use all proper safety precautions when handling the bath fluid in use (refer to the Material Safety Data Sheet included with the bath fluid for more detail).

Bath Liquid Guidelines When selecting a liquid for use in the TE-1500, keep the following guidelines in mind: c s i y t i i t a i t s i r r e f f i t c i l e .
Procedure The bath liquid in the TE-1500 should be removed by siphoning action. A general purpose siphon (see Figure 6) is available wherever kerosene heaters are sold. This simple plastic device has an integral squeeze pump to start the siphoning with a long, straight input hose and a flexible output hose.
Control Chassis rear panel. This will empty any remaining fluid from the Overflow Jar and connec- tion hoses into the bath. Turn off the TE-1500 after the remaining fluid has been returned to the bath vessel.
BATH OPERATION Setting the temperature Front Panel Description The controls for the TE-1500 are divided into 4 different “control areas”, as shown on the front panel (see Figure 7). In this manual, the four control areas will be abbreviated as follows:...
CAUTION Do not operate the TE-1500 with an inadequate volume of liquid in the bath vessel. 3. Turn on the LIGHTS switch on the front panel and verify that the lamps illuminating the interior of the bath are on. Temperature control options There are two ways to set the TE-1500 Bath temperature, preset or custom temperature selection.

Otherwise, the temperature stability of the Bath will not be optimum. 4. After the bath equilibrates, release the lock on the TA - VARIABLE switch. ® TE-1500 Thermoelectric Constant Temperature Bath CANNON Revision 1.1b—November, 1998; CANNON ® Instrument Company...

2. Turn the TA - FIXED dial to the midpoint (500). 3. Move the TA-SELECT switch to the right (the VARIABLE position). 4. Adjust the +10°C trimpot until the thermometer in the TE-1500 Bath indicates that the Bath is now controlling at +5°C (this may also involve adjusting the TA - FIXED dial).

Appropriate eye protection (safety goggles) is also required. Cleaning the painted surfaces and front panel The finish of the TE-1500 is a baked-on epoxy enamel in colors of almond and black. This paint is virtually immune to most solvents, however, if acetone is rubbed on the painted surfaces, the paint will be removed.
Eye protection should always be worn when using compressed air. Cleaning the bath window The viewing window on the TE-1500 is constructed with four panes of low emissivity glass with all panes tempered for safety. The space between these panes are filled with a gas and sealed to provide a frost-free viewing win- dow.
