    The Fluke 754 is WAAAYY better than the Slap-Chop! You really can set it and forget it. One of the hardest things things learning the 754 is figuring out the menu structure and where to find everything. I learned how to use it several years ago and it wasn't all intuitive but its worth a little effort. What is really nice is that it will document your calibrations and troubleshooting. Many people ask if you can calibrate an RTD. The answer is no. Thermocouple? The answer is no. Can you calibrate an analog card. Sometimes. Can you calibrate a temperature transmitter? Sometimes. ?? Many of them you can, some transmitters do not have any adjustment except possibly by the factory. Can you verify all of these things? YES. AND you should be verifying your instrumentation is accurate to ensure efficiency and safety. Because the Fluke 754 documenting calibrating is a little tricky at first. I thought I would provide a few steps on how to set it up to perform a temperature calibration because those can be very time consuming. 1. Connect your leads to your transmitter. 2. Turn on the calibrator. 3. Select the measure/source button (this toggles between 3 screens). 4. Set your measurement up for mA. 5. Select measure/source button. You will select drywell. (This will only work with certain model drywells and you need to have the correct cable RS232. As well as, the correct processor). 6. Select Menu and enable Loop Power. 7. Exit the Menu and go to your split screen by selecting measure/source. 8. Select As Found at the bottom (F1) 9. For Temperature Transmitters select Instrument. 10. Enter in your signal (usually 4-20) enter tolerance %. The delay is very important with drywells because it takes time to get to the desired setpoint. I usually do about 10 mins on the 9100S. Enter your LRV and URV. Select your strategy (3 up/down, 5 up/down, etc.). 11. Select Auto Test. 12. Go do other calibrations or troubleshooting while your calibration is running. 13. Come back and ensure your test points are recorded. 14. Select done. 15. Enter in a transmitter tag. 16. If out of tolerance, adjust the error. 17. Select "as left". 18. Repeat. Its pretty easy once you do it a few times. Also, its a huge time saver if you have a lot of work to do. Please let us know if you need help with your calibrations, loop checks, troubleshooting or installation. In case you need help: We are a UL508A panelshop. We are a licensed electrical contractor. We offer NIST traceable calibrations. We do PLC and HMI programming and troubleshooting. We help crosstrain electricians and technicians into the field of instrumentation and controls.

    We installed a bunch of level and flow meters for chemical storage and dosing sites over a year ago. We went back 1 year later to verify flows and levels are reading accurately. So far, so good. My favorite level transmitters have bluetooth capabilities to configure, troubleshoot, verify and trim if needed. #instrumentation #E+H #Easy
