When enabled, all available channels aredenoted by channel LEDs that are turned on (dimly lit or brightly lit). Channels not availableare denoted by channel LEDs that are turned off.Contrast between on and off LEDs can be increased by disabling the LED Graticule.

Each LED is either off or brightly lit.NOTEIf the main CPU firmware is not compatible with the LED display firmware,the following error will occur when trying to disable the LED Graticule.ERROR:ID CODE = +551Incorrect software revisionIf this error should occur, contact Keithley to resolve the firmware incompatibility.Programmingexample10 OUTPUT 707; “:disp:wind3:grat on; grat?”20 ENTER 707; A$30 PRINT A$40 ENDLine 10Disables the LED Graticule and then queries the state of the LED Graticule.5-74
