-Primary Test: Does the sensor read near zero when no force is applied? Does the sensor read a positive value when pulling, and a negative value when pushing?
-Secondary Test: Point the hook downward. With nothing attached, note the reading. Then, hang a 500 g mass from the hook. Note the new reading. Is the difference approximately 4.9 N?
Confirm that the switch setting on the sensor is appropriate for the experiment. In general, you should use the +/-10 N range if you can. If the forces exceed 10 newtons, use the +/-50 N range.
Was the sensor properly zeroed? If you plan to use the Dual-Range Force Sensor in a different orientation (horizontal vs. vertical) than it was calibrated, zero the Force Sensor in the orientation in which you want to use it. This additional step makes the sensor read exactly zero when no force is applied.
-Calibrate? No. The sensor is set to the stored calibration before shipping.
-If you wish to calibrate the sensor, you will conduct a two-point calibration.
First point: Remove all force from the sensor. Enter 0 as the first known force.
Second point: Apply a known force to the sensor by hanging a mass from the hook on the end of the sensor. Enter the weight of the mass (Note: 1 kg applies a force of 9.8 newtons). For calibration using the +/-10 N range, use 300 grams of mass (2.94 newtons). For calibration using the +/-50 N range, use a one kilogram mass (9.8 newtons). Do not exceed the selected range setting during calibration.
