2.3.3.5 Trigger Delay
The trigger delay is the amount of time between the activation of a trigger (via IEEE, Handler or
front panel) and the 1855 making the measurement. The delay time can be programmed from
0000 to 9995 seconds. The instrument default value is 0000 seconds. To change the TRIGGER
DELAY press [SYSTEM SETUP], [SYSTEM CONFIG] and the down arrow [⇓] until the box
next to TRIGGER DELAY is highlighted, then press [F1] = DIGIT UP to increase the delay
time, [F2] = DIGIT DOWN to decrease the delay time or [F3] = DIGIT to move over a decimal
place.
