Returns delay time in seconds.
DELAY?
The DELAY command programs the time interval between the trigger event and the first sample event
in seconds. Although the valid parameter range is from 1E-7s to 6000s, the Model 2002 rounds any
value below 1ms (0.001s) to 1ms. Specifying a delay of 0 selects the minimum delay time possible.
Program 50ms delay.
DELAY 50E-3

DISP?
The DISP command enables/disables the multimeter's display and may be used to send a message to
the display, or to clear the display. ON selects normal operation. OFF displays a message if a valid
message parameter has been sent; otherwise, all dashes are displayed. Readings are no longer dis-
played, and the display is not updated, except to service front panel keystrokes. The MSG parameter
simply displays a message on the front panel, and the CLR parameter clears the display entirely. The
parameter is any string up to 52 characters enclosed in double quotation marks.
