Chapter 5 Getting Started
5.1. Initial Setup
Set the device on a benchtop. Make sure the device is switched off and the power cord is disconnected. All wiring
and configuration should be done before the unit is powered on.
5.2. Heater Connection
Most resistive heaters do not have a polarity, so simply wire the heater to pin 1 (Output Heater +) and pin 2 (Output
Heater -) of the Hirose connector on the front panel, as shown in Figure 3. The TC300 is compatible with most
resistive heaters but can achieve maximum efficiency when paired with heaters with 12  resistance.
Figure 3 Heater Connection
5.3. Thermal Sensor Connection
The TC300 is compatible with a variety of different types of temperature sensors including:
 Thermistors
 Platinum Resistance Temperature Sensors
 Thermocouples
 AD590
Each one requires a slightly different wiring and set up.
5.3.1. Thermistors
The TC300 is compatible with thermistors with resistance ranging up to 999 k. Most thermistors do not have a
polarity. To connect a thermistor to the TC300, simply wire the thermistor to pin 4 (Sensor +) and pin 5 (Sensor -)
of the Hirose connector as shown in Figure 4.
