Using Current Indications During Locating

Both the Transmitter and Receiver will indicate cable current. These current indications will help to select a trace frequency, identify the correct cable and troubleshoot the set up.

When using the direct connect method, the Transmitter output current number is displayed. A "LO" display, or number less than 50, indicates a weak tracing signal. A number higher than 70 represents a strong tracing signal. When the Receiver is used to find the cable near the Transmitter connection point, the current number displayed in the Receiver should correspond (within 5 points) to the Transmitter number if: you are over the correct cable, and most of the signal is flowing in that cable.

Note: On the Transmitter every ten units on the current display represents a factor of two in current magnitude. On the receiver, trace current readings for 512Hz, 560 Hz and all additional auxiliary frequencies (except 31.5 kHz) are now displayed in milliamps. For all other trace frequencies every ten units on the current display represents a factor of two in current magnitude.

When the Transmitter signal is applied using the Dyna-Coupler, the Transmitter current display indicates the current in the coupler and not in the cable. In order to get a measure of the cable current, point the Receiver at the exposed cable about two feet from the Dyna-Coupler. This will be the current number that should be used to identify the correct cable.

In general, when the Transmitter is set up to apply more current on the target cable than any other cable, the cable can easily be identified because the Receiver current reading will be highest.

Note: Since some of the signal in the cable will bleed into the earth, it is expected that the Receiver current indication along the cable will decrease gradually away from the Transmitter. This effect is more pronounced at higher frequencies.

2273 specifications

3M 2273 is a high-performance double-sided tape that is engineered for a variety of demanding applications in both industrial and household settings. This tape is particularly well-regarded for its versatility and strong bonding capabilities, making it a popular choice among professionals and DIY enthusiasts alike.

One of the standout features of 3M 2273 is its robust adhesive technology. It utilizes a proprietary acrylic adhesive that provides excellent bonding strength on a wide range of surfaces, including metals, plastics, glass, and painted materials. This versatility allows users to apply the tape in different scenarios, whether it’s for mounting, joining, or attaching parts. The ability to adhere to challenging substrates without the need for additional primers or surface treatment simplifies the application process.

The tape is designed with a unique combination of a thick carrier film and a high-quality adhesive layer, which contributes to its durability and reliability. The thick backing provides excellent conformability, allowing the tape to maintain its adhesion even on irregular or textured surfaces. This feature is particularly valuable in automotive, aerospace, and construction industries, where the integrity of bonds is crucial.

Another key characteristic of 3M 2273 is its temperature resistance. This tape can perform effectively in a wide temperature range, making it suitable for applications exposed to heat or cold environments. Whether it’s used in manufacturing processes or for outdoor projects, the tape maintains its bonding properties, ensuring long-lasting performance.

The transparency of 3M 2273 adds to its appeal, particularly for applications where aesthetics are important. The discreet appearance allows for clean finishes, making it ideal for use in electronic devices, graphics, and signage where visible seams could compromise visual appeal.

Furthermore, 3M 2273 is easy to manipulate, allowing for quick and efficient application. The tape is available in various widths and lengths, catering to the diverse needs of users. It also boasts excellent shear strength, which helps it resist slippage and provides a secure hold over time.

In summary, 3M 2273 stands out in the realm of double-sided tapes due to its exceptional bonding capabilities, temperature resistance, and versatility across a variety of substrates. Its reliable performance and user-friendly design make it an essential tool in both industrial settings and everyday applications, ensuring that it meets the rigorous demands of users worldwide.
