The Answer to Locating in Steel or Ductile Iron Lines Now your locates don’t have to stop where the steel begins. Penetrating steel or ductile iron requires a very low frequency, and the 16 Hz LD Series transmitters have it. Use it with your in lines of almost any material – steel, cast iron or nonmetallic. You’ll also find that 16 Hz is far less vulnerable to electrical interference than 512 Hz. 16 Hz electronics require significant trade-off of size vs. Power, so we offer 2 versions to fit your needs: • The LD-14 is the most powerful, but may be too long for the line you’re working in. • The LD-9 sacrifices some power to gain the advantage of a smaller size.
My Noma Backup Power System 1800, which I purchased June 28 2008, stopped functioning properly and when I initially called too see what service was available and asked what the warranty period and was was told they would need a receipt before they could tell me anything.

• 16 Hz – a very low frequency with the advantage that it will penetrate steel or ductile iron lines (as well as cast iron and nonmetallic). It is compatible with any gear that operates at 16 Hz. • 512 Hz – the industry standard frequency for locating in cast iron or nonmetallic lines. It is compatible with any other manufacturer’s 512 Hz equipment. • 8 KHz – a high frequency that works in nonmetallic lines only, but is very efficient and offers good range.

Works with any 8 KHz equipment. • 223 KHz – suitable for nonmetallic environments only. Only Prototek makes equipment that operates at this frequency (AR-1 and ATP-12).
You must match the transmitter’s frequency to the receiver’s frequency. A 512 Hz Transmitter will not work with a 223 KHz Receiver, etc. The Range of a transmitter is the maximum distance, in feet, your receiver can be from the transmitter and still pick up a usable signal (using fresh batteries in both transmitter and receiver). • For 16 Hz transmitters the range is very dependent on the wall thickness of the pipe, so the range given is pessimistic, i.e., for the thickest typical lines.
Range in nonmetallic lines can be up to 3 times that in steel; the range in cast iron is slightly less than in nonmetallic. • For 512 Hz transmitters, is made specifically for cast iron but works great in nonmetallic lines to. The range of an FD-10 is about 10 feet in cast iron and 15 feet in nonmetallic. • For 8 KHz transmitters, the range is for nonmetallic lines only – its signal will not pass through any kind of metal. • For a 223 KHz transmitter (ATP-12), the range is also for nonmetallic lines only. The range of an ATP-12 flushable transmitter is about 12 feet. Its signal will not pass through any kind of metal.
Note: These Range distances apply to Prototek receivers only! We cannot guarantee your results with other receivers.
“Tone” refers to the type of signal emitted by a transmitter. All of our transmitters are one of these types; many are available either way. Which tone should you choose? Here are some considerations about each type: C – Continuous or “Solid” Tone Pros: • available on almost all Prototek transmitters • best to use for determining precise depth • compatible with most other manufacturers’ equipment Cons: • harder to distinguish signal from interference • shorter battery life B – Beeping (on/off) Tone Pros: • easier to distinguish signal from interference • longer battery life Cons: • difficult to use for determining depth • won’t work with LF2000 or LF2200, or many other manufacturers’ digital equipment.
Great, your contains between 70 and 160 characters spaces included (400 - 940 pixels). A good meta description acts as an organic advertisement, so use enticing messaging with a clear call to action to maximize click-through rate. They allow you to influence how your web pages are described and displayed in search results. Ensure that all of your web pages have a unique meta description that is explicit and contains your (these appear in bold when they match part or all of the user’s search query). Check your Google Search Console account (Click 'Search Appearance', then 'HTML Improvements') to identify any issues with your meta descriptions, for example, they are too short/long, or duplicated across more than one page.
Allows you to add a description to an image. Since search engine crawlers cannot see images,.
Alternative text also helps makes an image more likely to appear in a Google image search and is used by screen readers to provide context for visually impaired users. It looks like you're missing alternative text for 60 images on sibsamogon.ru.
Check the images on your website to make sure accurate and relevant alternative text is specified for each image on the page. Try to minimize the number of alt text characters to 150 or less (including spaces!) to optimize page load times. This value is called 'link juice'. A page's link juice is split between all the links on that page so lots of unnecessary links on a page will dilute the value attributed to each link. There's no exact number of links to include on a page but best practice is to keep it under 200. Using the attribute in your links prevents some link juice, but these links are still taken into account when calculating the value that is passed through each link, so using lots of NoFollow links can still dilute PageRank. Contain the list of your URLs that are available to index and allow the search engines to read your pages more intelligently.
