4.3 2-Point Calibration
Two-Point Calibration is recommended if calibrated weights are available to perform the calibration.
Point 1 is with no load and Point 2 is with load. You could calibrate Point 2 at full load or at the
maximum weight range you would be using.
• Ensure
UNIT and LC commands have been setup prior to starting the calibration.
• To select the 2 point calibration mode, type: CAL 2 <Enter>
• Remove all loads, type: 2PCAL xyz <Enter>. (Note: xyz is the weight to be loaded for
Point 2.)
• DI-100 responds with “Apply Point 1 Load of 0, LB Press C when ready or Q to quit”.
Ensure no load is applied to the load cell and type: C
• DI-100 responds with “Apply Point 2 Load of xyz, LB Press C when ready or Q to
quit”. Load the calibrated weights, stabilize the load, wait 10 seconds, and type: C
• DI-100 responds with a number and “Calibration complete!” message. The number
reported represents the computed mV/V rated output.
Please note both UNIT and LC have to be correctly configured for DI-100 to properly compute the
mV/V. The calibration data and parameters are saved permanently on the DI-100 until you perform
another 2-point calibration. You may start to use your load cell now:
• To tare (i.e., reset the zero) the load cell, type: TARE <Enter>
• To view current weight once, type: W <Enter>
• To view current weight continuous, type: WC <Enter>
• Pull or push on the load cell, the weights should change accordingly.
• Press
<Enter> to stop the scrolling.
