I need to calibrate my T1 DYNO load cell. How?

Solution

Before you calibrate the load cell, you need to have the "E-Cal Output" value from your load cell's calibration certificate. This should be a value in pounds in the 32,500 - 33,500 range. (If it's a little outside this range, that's alright.) It's listed in the right-hand column of numbers, about halfway down the page. If you don't have the calibration sheet, find the serial number of your load cell (it's printed on a label on the load cell) and contact Theta Enterprises for assistance.

Once you have the E-Cal Output value, here is the procedure. It can be done in the office, with the T1 Dyno (and load cell) on the desk next to you:

  1. Make sure the load cell is connected to the T1 Dyno, that the T1 Dyno is connected to the computer's serial port, and that the T1 Dyno is turned on.
  2. Start DYNOSTAR, then enter the Options dialog by selecting the Tools menu, then the Options... item.
  3. In the Measurement Settings box, make sure that "Theta Enterprises T1 Dyno" is your dynamometer type.
  4. Click the Configure... button. You'll get a new dialog box called "Configure T1 Dyno Interface."
  5. In the Horseshoe Load Cell box, click the Calibrate Now... button. You'll get a new dialog box called "T1 Dyno Load Calibration Assistant."
  6. At the bottom of the dialog box, you should see a "Nominal load" value. This tells you that all the connections are working. If you see a message that tells you the "dyno does not appear to be responding," check the connections.
  7. If the connections are OK, then, with no load on the load cell, click the "Measure zero load" button in step 1 of the dialog box.
  8. While holding down the "LOAD CAL" switch on the T1 Dyno, click the "Measure calibrated load" button in step 2 of the dialog box.
  9. Enter the "E-Cal Output" value from your calibration certificate into the indicated field in step 3 of the dialog box.
  10. Click OK on the three dialog boxes to return to DYNOSTAR.
