TE-BBR Instruction and Operation Manual
Check Function of TE-BBR Cooling Modules
This technical note provides a preliminary procedure for checking function of the thermoelectric cooling
modules mounted internally to the TE-BBR bath. The procedure will check the integrity of the electrical
circuit defined by input and output leads from the modules.
Tools Required: Phillips screwdriver, multimeter
Procedure
1. Remove power from the TE-BBR unit and unplug the MAINS power source.
2. Using a Phillips screwdriver, remove the four screws securing the left rear side panel of the TE- BBR.
Remove the panel to reveal the internal electronics. Refer to Figure 27.
Caution: The TE-BBR is designed with a capacitor capable of holding a strong
charge. Do not touch the capacitor or other internal components unless
specifically instructed to do so in this procedure.
