Vernier LabPro User’s Manual B-1
Appendix B: Beep Sequences
LabPro makes four kinds of sounds or “beeps.”
 A “good” beep is a medium tone followed by a high tone.
 A “caution” beep is a medium tone followed by another medium tone.
 A “bad” beep is two high tones.
 A “tick” sound is made when a key is pressed.
The following bullets explain when beep sequences occur and what the beep sequences mean:
 When LabPro completes initialization, you will hear the startup sequence: bad beep, caution beep,
good beep (6 total beeps, plus LEDs light up in this order: red LED, yellow LED, and green LED)
 When you press the QUICK SETUP button,
 the caution beep sounds if a sensor is attached to LabPro.
 the bad beep sounds if no sensors are attached to LabPro.
 When LabPro is connected to a calculator during sampling commands,
 the caution beep sounds when initializing data collection.
 the caution beep sounds when starting data collection (transition from pre-store to store).
 the caution beep sounds when completing data collection.
Note 1: If the sampling timing causes the beeps to run together, the LabPro software may not sound all
the beeps.
Note 2: You will not get all the beeps when Fast Sampling is enabled.
Note 3: You will not get all the beeps when using triggering.
 When you set LabPro for manual trigger and press the START button, a caution beep sounds.
 When you press the TRANSFER button,
 the good beep sounds when the transfer succeeds.
 the bad beep sounds if the transfer fails for any reason.
 When an overcurrent condition is detected, five bad beeps sound. (This causes an error, which
causes even more beeps to sound.)
 When LabPro begins a full self-test, three good beeps sound.
 When self-test completes,
 the good beep sounds if self-test passes.
 the bad beep sounds if self-test fails.
 When LabPro’s base code detects an error in the commands sent from the host, a bad beep sounds
twice.
 When LabPro powers up,
 two bad beeps sound if the base code is not loaded.
 three bad beeps sound if the power-up self-test fails.
 During base code download, three bad beeps sound when any errors occur. (The unit resets and
then the two bad beeps mentioned in the previous bullet sound.)
