Page 4: Components
The TC-10 temperature control system is designed for heating purposes in electrophysiological experiments. The TC-10 system is housed in a 19 inch standard cabinet, with a built-in power supply and cooling elements for the power devices. The TC-10 guarantees low noise operation and has special protection features to prevent the preparation from damage. -

Page 11: Modes Of Operation
0 V to 12 V. The ALARM circuit (see below) is disabled in this mode. The TC-10 is designed with an unipolar output (0-12 Volt DC). If a resistive load is used, the system can be used for heating purposes in all modes (SENSOR and DIRECT). -
Page 12: Setting The Desired Temperature
1. The easiest way is to use the digital potentiometer DESIRED TEMP. / °C. The temperature can be set from +03.0 °C to +60.0 °C, resolution: 0.1 °C. If the TC-10 leaves this temperature window the internal shut-off unit disconnects the power output. -

SENSOR are using the same channel. Otherwise the heating device may be damaged due to overheating. In the following it is assumed that you use heating devices delivered by npi or ALA Scientific Instr. with 12V operating voltage. Please follow these instructions step by step to avoid problems in adjusting the instrument. - Page 17 As mentioned above it is very important that the sensor element and the heating element are in good thermal connection. In Figure 6 the time course of temperature regulation of the TC-10 is shown. As resistive load a bulb (12V, 21W) was used. The temperature sensor was fixed directly on the bulb and sensor and bulb were wrapped with foam.

TC-10 User Manual ________________________________________________________________________________________________________________ 6.1. Operation with HPT-2A Heated Perfusion Tube (discontinued) For use with HPT-2A from ALA please follow these hints. Always use the LIMITER. Do not set the LIMITER to more than 50% for a longer time, since the HPT-2A will melt if operated at more than 5V. -
