    I have the sman460 and I don’t live too far from the fieldpiece store in Orange County, California. I had them replaced once because a sensor was bad, customer service is great! In regards to the temp clamps, I feel like they’re not accurate sometimes. Someone from fieldpiece calibrated them for me but I sometimes get weird reading out in the field regarding superheat and subcool. Might it be that the copper line are rusty and I don’t get good temp reading? Or should I get better temp clamps? Any suggestions? Great video!

    • @briand4000
      @briand4000 6 лет назад +2

      Yeah, me too. I will scrub off the tube with a scotchbrite pad if it's really oxidized and temporarily put both clamps on the same tube to cross check them to each other. Can also tape on another bulb from a separate thermometer to verify. I use the 360 as it has no bluetooth which is required where I work for security reasons (DOE nuke lab). The Fieldpiece is an excellent unit and gets a lot of runtime on a set of batteries.

    • @acservicetechchannel
      @acservicetechchannel  6 лет назад +1

      Thanks Armando and Brian, I put out a calibration video for checking the temp sensors. I would only use Fieldpiece temp clamps in their ports. Make sure to only use the specific sensor that was calibrated for that gauge set wire connection. If you switch the temp clamps with each other or put in a bead type sensor in without recalibrating then the temp reading will be off. I always use the Fieldpiece ST4 if I question a temp reading. I keep the bead type temp sensors in the ST4. Sometimes I prefer the bead type over the clamps for accuracy since they are small and you can insulate over them with armoflex if needed, thanks!

    • @OcRefrig

  • @Jiggywithfacts
    @Jiggywithfacts 6 лет назад +3

    Great video as always. Do you need a different Manifold gauges for each different type of refrigerant ? Cuz the Mansfield is capable of reading many refrigerant so I have to buy a new Mans field gauge for r22, and another one for r410a and so on. That can get expensive.

    • @acservicetechchannel
      @acservicetechchannel  6 лет назад +3

      With the yellow jacket gauge sets yeah we usually keep one set for use with each type of oil but I don't expect people to have 2-3 of the SMAN460's. You could blow it out with nitrogen for each use or keep two sets of hoses, one set for POE and one for Mineral oil. We do what we can without going crazy, thanks JiggyPatel and great question!

    • @OcRefrig
      @OcRefrig 6 лет назад +2

      No, You Don't Have to Have Different Manifolds for Different Refrigerants. Just Keep Your Manifold & hoses Clean and clear of Debris. Keep hose ends capped with brass flare caps. Keep knobs in the center position , and NEVER keep pressure in your hoses and manifold.allways keep caps loose on hoses and valves in center position. Keep your manifold in a Hard case or Hang in your truck in a safe spot. Digital Manifolds Need to be Treated Like the high priced piece of test equiptment they are. the More u Protect them and take care of them the Longer they will last and Give u better service. That said, you Need to Keep at at least two manifolds on your truck at all times. manifolds will leak after a period of time deending on manifolds. its best to own a set of analog manifolds too. they are better for checking compressor valves on pump down and have no digital sensor lag. they are also more durable than digitals. i personally recommend imperial 600 or 800 series analog manifolds for day to day use. they have served me well for 37 years. check out nor-cal refrigeration page for the manifold he uses too analog type. i think its a yellow jacket. titan or brute one or the other. best to allways have one Analog and one Digital manifold on the truck. at least minimum.

    • @acservicetechchannel
      @acservicetechchannel  6 лет назад

      I have always had good experience with those simple yellow jacket 2 port manifolds and it was always easy enough to have three sets of them in the truck with their hoses. Imperial is certainly good too! Yeah I don't think it is worth having more than 1 SMAN in the truck. The issue always is always how to keep the hoses clean. I do agree not to tighten the hose ends but do cap them off. The problem is if you get humidity into the hoses and we all hang our sets like a U with the hoses coming back up and connecting at the port at the bottom of the SMAN, the oil collects in the bottom of the U and doesnt get a chance to get out. That oil can mix with the air and contaminate it and then we put that small amount of oil in the system possibly or accidentally. You can blow those hoses out and the SMAN with some nitrogen every once in a while if you aren't naturally doing it with pressure tests. That is nice that OC puts his manifold in a case when he is not using it. We do what we can but like I said, don't drive yourself crazy. We do what we can for the quality of the equipment and for the customer, thanks JiggyPatel and OC!

    • @acservicetechchannel
      @acservicetechchannel  6 лет назад +1

      This is just my personal preference but as an apprentice I would buy the three appion valve core removal tools, the cps micron gauge and a 3 port manifold gauge set, hoses with valves on the end. We do vacuums without the manifold gauge set involved mainly nowadays. You can always move up into the digital gauge set as time goes on, especially with the comparison of price between the two being close to 7 times more expensive. I would like to see you get more of the smaller tools needed first such as valve core removal tools, vacuum hoses and the ST4 dual temp reader. I have these tools linked at amazon.com/shop/acservicetech as well I put them below.
