grammed event is required to cause a measurement
(device action).
The instrument is placed in the external trigger mode by
pressing the EX TRIG key. In this mode, a device action
(measurement) will occur when the TRIG key is pressed,
a bus trigger (*TRG or GET) is received, or an input trig-
ger via the TRIGGER LINK connector is received. After
the device action (measurement), an output trigger
occurs and is available at the TRIGGER LINK connector.
Refer to the Model 2010 User’s Manual for details on
using the trigger link. Pressing EX TRIG a second time
returns the instrument to continuous operation.
Delay — A programmable delay is available before the
device action (measurement) occurs. It can be set man-
ually or an auto delay can be used. To set a delay, press
SHIFT and then DELAY. Use the

times are listed in Table 3-2 of the Model 2010 User’s
Manual.
