Access to any channel parameter is provided through the front panel or via the computer interfaces. The SR630 can store up to nine entire instrument configurations, including thermocouple type and temperature limits for all 16 channels. There are four analog outputs on the rear panel of the instrument. These outputs have a full scale range of 10.0 VDC, with 5 mV resolution. The outputs can be set directly through the computer interfaces, or they can output a voltage proportional to the reading on channels one through four.
X is either temperature or voltage, depending on the setting for each channel.
You may use the analog output to drive chart recorders, or they can provide a feedback signal for proportional temperature control systems. They may also be used as general purpose analog control signals, since each level can be set via the computer interfaces to a fixed value. Each channel can be programmed individually with an upper and lower temperature limit. An audio alarm and a relay closure indicate when any channel exceeds its preset temperature or voltage limits. The front-panel LED display will indicate which channel has exceeded its limit.
