2.7 Instrument Use And Controls
With four front-panel buttons and one handle button (as seen in front-panel drawing in front
of manual), the Ludlum Model 3014 offers many features in a small package. Each button
may be pressed and held for a predetermined length of time, signified by instrument beeps,
to access unique instrument features. As the button is pressed, the instrument will beep to
indicate the user has reached a new level of button access.
• A short press and release, or one beep, indicates the instrument button is at the first
level of operation.
• A long press and release, or two beeps, indicates the instrument button is at the second
level of operation.
• An extra-long press and release, or three beeps, indicates the instrument button is at
the highest level of operation.
By default, the majority of functions are assigned to short presses of the buttons.

• Power On: Press for approximately one second and release (all LCD segments will ac-

• Power Off: Press and hold for approximately five seconds. The display will show a 3,

will return the device to the previous state of operation. At completion of the shutdown
count, the LCD will go blank (unless a USB cable is connected in which case the USB
icon will flash).
