The Microphone (MCA-BTA) output signal is sent to the interface on two different lines:
1) A signal centered at 2.5 volts is on the standard 0-5V output line.
2) A signal centered at 0 volts is on the alternate +/-10V output line.
Here is a pi...

Primary Test: Plug in the sensor and run the data-collection program. Hold the tip of the sensor in your hand and check for the tem...
The currently shipping sliding carriage on the Centripetal Force Apparatus (CFA) has a mass of approximately 51.0 g. This is an injection molded part so there will be some variation from unit to unit.
There is an older version of the sliding carri...
Yes, there are a few sensors that need to be stored properly in order to stay in good condition.
Oxygen Gas Sensors should be stored upright. This is easily done by storing them in the bottle in which they were shipped.
Dissolved Oxygen Probes...
- Set a slow drop rate. For the best, most accurate data, we recommend setting the rate at 2 seconds per drop or slower. A slow rate provides enough time for each drop of titrant to be thoroughly mixed in the solution and the pH sensor (or other sens...
The ideal technique is to use two products that were designed specifically for this situation:
Bracket that attaches the Dual-Range Force Sensor (DFS) to a Pasco cart: Adapter for PASCO Cart (PCA-DFS)
Mass that fits onto a Pasco cart with a DFS: ...
Light Sensor (LS-BTA)
Specifications and User Guide
Troubleshooting
Primary Test: Make sure that the sensor is not picking up the 60 or 120 Hz flicker from fluorescent or other lamps. Eliminate all artificial light source...
It depends on the age of the sensor. Vernier O2 Gas Sensors manufactured after April 2007 can be refurbished with a new electrochemical cell, whereas sensors manufactured before then cannot. (The newer O2 Gas Sensors can be identified by the recessed...
