have been set for –10 dBm and the display units are subsequently changed from dBm to Watts, the system still checks for the reading to rise above –10, even though the display units type has been changed. Enter a value from:

Units	Min	Max

dBmV	–53.00	147.00

Select ON or OFF to enable or disable low limit checking.

If FAIL HOLD is ON, both the screen FAIL indicator and the BNC output are held in the fail state whenever the limits specified for the channel have been exceeded, regardless of whether the reading subsequently goes into pass or not. This state remains until FAIL HOLD is turned OFF.

BEEP	If BEEP is ON, and FAIL HOLD is OFF, whenever the limits speci-
[FBEEP]	fied for the channel have been exceeded, a single beep sounds.
	If fail BEEP is ON and FAIL HOLD is ON, whenever the limits
	specified for the channel have been exceeded, a beep will sound
	once every second until FAIL HOLD is turned OFF, or the CLEAR
	key (CLR) is pressed.
	The FAIL indication is not affected by the CLEAR key, and can only
	be cleared by turning FAIL HOLD off. If a limit fail happens again,
	the alarm will sound again.
