What's happening at NETS?



After a long dormant period, the batteries will lose some of their charge. Reset your 3440 and 4640 battery life to peak life at 190 hours and clear the elapse time back to zero.  If you are unsure of how to reset the battery life refer to our FAQ page and follow the steps found there.  Then plug the gauge into the charger and allow charging overnight (or at least 8 hours).  This will give the batteries top charge and will avoid the battery low indicators or worse, it just won’t turn on, during the first trip out.



An excellent way to start the spring is to take standard counts at the shop.  Make sure that no other nuclear gauge is within 25 feet of the gauge standardizing.  This is very important.  Otherwise, the counts will be off.  Take up to five standard counts, making sure you save the counts, reloading the memory with fresh standards should help increase accuracy.  Check these new counts with the last counts preformed.  They should be within ASTM standards for accurate test results.  If you have any concerns, please feel free to contact John at 410-751-5090.



Occasionally, the bottom of the gauge needs to be cleaned.  Make sure nothing is stuck to the bottom and that the source rod moves freely.  Remove the four base plate screws and the sliding block, and clean thoroughly.  This should help the rod move smoothly.  Do this whenever the rod becomes too stiff to work properly. Follow your operators’ manual for exact procedures for your gauge.  

These few steps will help the first time in the field go without problems.

Winter is a popular time for gauge calibrations, but not the only time.  As your gauge calibrations come due, NETS will continue to ensure your nuke gauge will come back looking and working its best.  During the calibration process, we clean and occasionally paint the topshells to look almost new.  We clean and lubricate the bottom assembly and lube the source rod shaft so the rod works easily.  We check the voltage on your batteries and their ability to take a charge.  We inspect and adjust the electronics (and we have technicians with electronics degrees).  Then we employ a 3 block system utilizing a low, med and high-density blocks and a high moisture block as well.  A “statement of traceability “ regarding these blocks accuracy is including within the calibration report.  A gauge safety checklist and a leak test (if applicable) are also included with the calibration report.  See our CALIBRATION page for more info.


NETS hopes all of our current and future customers have wonderful holidays and a Happy New Year.
