calibration SeekTech SR-20
Dear Sirs We would like to know what is procedure used to calibrate that equipment , or , if OSHA 18000 has some inidcation or rule to calibrate that . Waiting your commnets JEsus Rubio
Typically calibration only needs to be done on a unit when and if the mast assembly has been dis assembled due to damage and or repairs. Calibration can only be performed at the factory. I am not familiar with OSHA 18000 or of it has any mandate on when locating tools are calibrated. If you have further questions please contact our Technical Support Department at 888-743-4333. Thank you RIDGID

What could be the ideal values of Signal Strength, Proximity Signal and Current strength of a very good locate
I had an interaction with Telecom professionals who works on laying and management of telecom OFC cables (with in built tracer lines). They had used different locators before but due to the shortcomings have upgraded to RIDGID locators. The concept of multiple ways of confirming a signal thru Signal strength, Proximity Signal and interactive trace lines were well appreciated. But they thought it would be ideal, if RIDGID can give reference values for Current strength, Signal strength and Proximity Signal which will indicate a strong locate or signal. These Reference values (in a range) can serve as a benchmark for strong locate or signal along with the current set of indicators.
One of the biggest advantages of the Seek Tech locating equipment is its ability to identify / trace a target utility with four different key indicators. What makes them all unique is the way they are calculated. Each indicator is calculated by using a different combination of antennas or calculations based on multiple readings. What this does in a sense is give the locator the built in “second, third and even fourth” opinion as to the location of the target utility. The problem with stating a certain utility should be within a certain range is that there are too many variables that the locator cannot control. The type and quality of the conductor, the soil conditions, and any interference in the immediate area can all affect the quality of a locate. What one should be looking for is the agreement of these indicators rather than a specified range for each on an individual basis. If I can get my balance arrows, my trace line, signal strength and proximity to all agree on a specific location I have the highest degree of confidence that I have made a good locate. The fewer indicators that I have in agreement, the more distortion that is present and this is an indicator that I need to change some of the things I can control, like improving my ground or changing my frequency.
