When a photogate is used with a LabPro in time-based data collection, photogate data is sent by the LabPro to the computer at the end of data collection. If you choose to stop data collection early by clicking the Stop button, the data will not be se...

Primary Test: Make sure that the sensor detects sunlight. A bright sunny day should approach a thousand Watts/square meter in irradiance.
Secondary Test: ...
There is no exact conversion factor.
The problem is that lux and W/cm2 are not simply different units, rather they are units for different measurements.
mW/cm2 is a unit for irradiance (energy falling on a surface) and lux is a photometric uni...
This is likely the result of the LabQuest desktop software not functioning as expected. To verify this, close all applications and quit the LabQuest Application (File > Quit). If the LabQuest shows a blue screen with Vernier on the side, the desktop ...
LabQuest platforms include an internal speaker and the Audio Function Generator app. The speaker can be used to hear a waveform produced using the Audio Function Generator, but due to the small size of the speaker, harmonic distortion is significant...
In September 2012, we updated the Conductivity probe with a new calibration on each switch setting to optimize it for small improvements in the hardware.
Pre-Sept 2012 Calibration values:
Low Setting = 65.7 uS/cm
Middle Setting = 847.2 uS/cm
...
The LabQuest internal temperature sensor measures temperature inside the LabQuest case. Its calibration is adjusted to approximate ambient temperature, but can deviate depending on the battery charge state and freshly powered warm-up time.
The ...

If the screen is not responding, try pressing the Home hardkey on the face of the unit. If the menu comes ...
The High Current Sensor uses a Hall-Effect sensor to measure the current. The Hall Effect is a magnetic phenomenon, so a strong magnetic field in the area the HCS-BTA sensor could cause a erroneous reading. Examples might include a electric motor or ...
