1. This trainer adopts modular structure, the experiment items and experiment circuits possess same or

    similar character are made into independent module. The modules can be combined flexibly according to

    training requirements of different levels, which is ideal for students to learn and operate.

2. Independent heat source and digital smart temperature control regulator are adopted to make it stable

    during experiment and avoid aging caused by traditional built-in heat source.

3. It is mainly composed of digital smart temperature control regulator (comes with independent heat source),

    mainframe box (including voltage source, constant current source, signal source, measuring meter),

    various sensor modules, sensors, etc.

1. Digital smart temperature control regulator: measuring range 0~400oC, comes with heat source and
    temperature control circuit.
2. Mainframe box:
    (1). DC signal source: 1K~10KHz, amplitude Vpp=8V
    (2). DC stabilized power supply: ±5V, ±12V
    (3). Constant current source: 0~20mA output, digital ammeter indication
    (4). DC voltmeter: measuring range 0~2V, 0~20V
    (5). Digital frequency meter: measuring range 0~100KHz
