Multipoint Calibration
Step 12: Load the machine to a desired load and press <ENTER> to set a calibration point (voltage measurement). The voltage value
is NOT displayed but it has been saved to nonvolatile memory. Write down the corresponding engineering unit value for
each calibration point. Repeat this step until all readings are taken.
Step 13: Press <STORE> to exit the measurement mode if fewer than five calibration points are used. (The program will
automatically proceed from Step 12 to Step 14 after the fifth reading.
Two Point Shunt Calibration
Step 12: Toggle Shunt to ON by pressing the 1) key and then and press <ENTER> to set a calibration point (voltage measurement).
The voltage value is NOT displayed but it has been saved to nonvolatile memory.
Step 13: Press <STORE> to exit the measurement mode.
Step 14: Input the corresponding engineering unit value for each measurement point. After all values have been entered, the
program will automatically generate the corresponding scale factors and store them to permanent memory.
DONE! READY TO VERIFY CALIBRATION
Step 15: To verify the calibration, exit out to the Indicating Screen and apply specific loads to the machine and compare the reading
on the controller with the standard.
5.3. What Occurs During Calibration
The calibration procedure allows up to five calibration points to be entered. Each successive pair of points is connected by a straight
line and the slope of each line is the calibration scale factor used for that region. This results in a piecewise linear function which
maximizes accuracy.
5.4. Saving Calibration Data
All calibration data can be transferred to and from the GaugeSafe Data Exchange software.
5.5. Setting Gage Length for an Adjustable Extensometer
Select Utils --> Transducer --> Cailbration. Enter the password. Contact ADMET techincal support if you have lost the password.
Select Strain (Encoder) press enter to leave pulses as is. Set the gage length to the current actual value and press enter to exit the
calibration screen.
