概要（Overview）

The model EC16HA temperature testing chamber is a 6 ft3 chamber that uses 600 CFM of vertical air flow with convection style heating and has a temperature range of -184°C to 315°C (using LN2) and -73°C to 315°C (using LCO2). The EC16HA utilizes an additional 200 CFM blower to pull in ambient air from outside the chamber to assist in cooling the interior workspace. It is then vented out the chamber's 3 1/2" diameter exhaust port. This feature allows the user to conserve coolant when cooling the chamber down from high temperatures. The ambient blower is mounted on the back of the chamber and can be controlled from commands issued from the front panel, inserted in local programs or through the remote interface. The EC16HA model temperature chamber uses the advanced and extremely flexible TC10 controller to provide features such as non-volatile memory to store user temperature profiles and parameters, an additional probe (for monitoring and control of product temperature), adjustable ramp rate, power down restart, analog and auxiliary I/O. Built in IEEE-488 (GPIB), RS232/RS422 remote interfaces are standard features on the EC16HA chamber. The chamber can function on it's own in an Automated Test Environment. Standalone operation is supported by a full function keyboard with a 2 line, 16 character LCD display. The electrically isolated chamber temperature and user temperature probe readings are normally displayed continuously and either probe may be used for control to ensure the proper temperature is achieved for the DUT. User programs are easily entered into the EC16HA chamber using a BASIC like command set programming language and stored in non-volatile memory along with user adjustable controller parameters. Probe calibration procedures are built in using a local menu driven format and parameters such as the PID coefficients are adjustable from the keyboard and remote interfaces. In addition, alarm function and sound level, BAUD rate, interrupt assignments and other communication port options are configurable from the front panel using an easy, menu driven format.
