POWER BUTTON

The SR850 is turned on by pushing in the power button. The video display may take a few seconds to warm up and become visible. Adjust the bright- ness until the screen is easily readable.The model, firmware version and serial number of the unit are displayed when the power is turned on.

A series of internal tests are performed at this point. Each test is displayed as it is performed and the results are represented graphically as OK or NOT OK. The tests are described below.

RAM This test performs a read/write test to the processor RAM. In addition, the nonvolatile backup memory is tested. All instrument settings are stored in nonvolatile memory and are retained when the power is turned off. If the memory check passes, then the instrument returns to the settings in effect when the power was last turned off. If there is a memory error, then the stored settings are lost and the default settings are used.

ROM This test checks the processor ROM.

CLR This test indicates whether the unit is being reset. To reset the unit, hold down the

backspace [←] key while the power is turned on. The unit will use the default set- tings. The default setup is listed in a later chapter.

CLK This test checks the CMOS clock and cal- endar for a valid date and time. If the there is an error, the time will be reset to a default time. Change the clock settings using the SYSTEM SETUP menu.

DSP This test checks the digital signal processor (DSP).

VIDEO DISPLAY

The monochrome video display is the user inter- face for data display and front panel programming operations. The resolution of the display is 640H by 480V. The brightness is adjusted using the brightness control knob located at the upper left corner. As with most video displays, do not set the brightness higher than necessary. The display may be adjusted left/right and up/down in the Screen Settings function in the SYSTEM SETUP menu.
