Power
The power switch is on the rear panel. The SR830 is turned on by push-
ing the switch up. The serial number (5 digits) is shown in the CH1 and
CH2 displays and the firmware version is shown in the Ref display at
power on.
A series of internal tests are performed at this point.
DATA Performs a read/write test to the processor RAM.
BATT The nonvolatile backup memory is tested. Instrument settings are stored
in nonvolatile memory and are retained when the power is turned off.
PROG Checks the processor ROM.
DSP Checks the digital signal processor (DSP).
rCAL If the backup memory check passes, then the instrument returns to the
settings in effect when the power was last turned off (User). If there is a
memory error, then the stored settings are lost and the standard (Std)
settings are used.
Reset
To reset the unit, hold down the [Setup] key while the power is turned on.
The unit will use the standard settings. The standard setup is listed on
the next page.
