5)Using a screwdriver that has a shaft diameter of 1/8” and a shaft length of at least 6”, turn the “Reactive” balance adjustment all the way counterclockwise (CCW) until the potentiometer stop point is reached. Turn the adjustment back clockwise (CW) 5 full turns to center the adjustment.

6)Turnthe“Resistive”balanceadjustmentallthewayclockwise(CW) untilthepotentiometerstoppointisreached.

7)Slowly turn the “Resistive” adjustment until the output reaches its lowest value. If the reading is negative adjust to the most nega- tive value possible.

8)Turn the “Reactive” balance adjustment slowly CW and CCW to obtain the lowest possible output value. Again, if the reading is negative adjust to the most negative value possible.

9)Repeat steps 6) and 7) until the output value is as low as these adjustments can make it.

10)Detune the instrument by turning the “Resistive” balance adjust ment ½ turn CW. This will bring the signal out of the baseline noise, which could otherwise cause non-linear response at the low concentration end.

NOTE: Due to minute differences between measuring cells and the electronics in the bridge circuit found in vari- ous instruments, some analyzers will have to be bal- anced at a point higher than 10% of scale while others can be balanced even closer to electrical zero. The 10% of scale recommended in step 6 of the procedure is an arbitrary starting point. If the bridge circuit can be easily balanced at this signal level, the procedure should be repeated at a point even closer to electrical zero. Conversely, if balance cannot be accomplished at 10% of scale, the operator will have to select a higher recorder set point for the procedure. In any case, the object is to accomplish dynamic balance with the lowest magnitude of analyzer cutout signal attainable with the analyzer at Range #1 sensitivity.

If a stable recording is achieved when the analyzer is operated on zero gas, erratic performance must be attributed to the customers sampling system

212R specifications

Teledyne 212R is a state-of-the-art underwater acoustic modem designed for robust communication in various marine environments. This advanced device is based on established principles of underwater acoustics and modern digital signal processing technologies, making it an optimal choice for applications ranging from oceanography to underwater robotics.

One of the standout features of the Teledyne 212R is its high data transmission capabilities, allowing for reliable communication at distances of up to several kilometers depending on environmental conditions. The modem supports various data rates, enabling flexible adaptation to the needs of different applications. This versatility makes it suitable for both low-bandwidth telemetry and high-data applications, such as video streaming from underwater drones.

The Teledyne 212R employs advanced modulation schemes that enhance its performance in challenging conditions. These modulation techniques, combined with sophisticated error correction algorithms, ensure the integrity of data transmission even in noisy environments. This resilience is crucial as it enables the modem to maintain communication in the presence of marine life, background noise, and varying temperatures.

Another remarkable characteristic of the Teledyne 212R is its compact and rugged design. Built to withstand harsh marine conditions, the modem is encapsulated in a pressure-resistant housing, making it suitable for deep-sea operations. Its durability ensures longevity and reliability, reducing the need for frequent maintenance or replacement, which can be costly in remote underwater settings.

Moreover, the modem features an array of integrated sensors that allow for real-time environmental monitoring. This capability can be pivotal for research organizations studying marine ecosystems or for oil and gas companies conducting underwater surveys. The ability to collect and transmit environmental data alongside operational data streamlines data-gathering efforts.

Ease of integration is another key aspect of the Teledyne 212R. It is compatible with a multitude of existing marine technologies and communication protocols, allowing for seamless deployment in diverse systems. This adaptability is essential for users requiring collaborative operations across multiple platforms, such as Autonomous Underwater Vehicles (AUVs) and remotely operated vehicles (ROVs).

In summary, the Teledyne 212R combines high-performance data transmission, advanced modulation techniques, rugged design, and environmental monitoring capabilities. This makes it an essential tool for anyone engaged in underwater research, exploration, or resource management, establishing it as a go-to choice in the field of underwater communication.
