CALIBRATION
-Calibrate? No. The sensor is set to the stored calibration before shipping.
-No calibration process is given in the sensor booklet.

ZEROING
If the sensor is not reading zero in the orientation in which you are using it, follow the procedure below:
1. Hold the Hand Dynamometer in the same orientation you plan to use it. Do not put any force on the pads of the
Hand Dynamometer.
2. When the readings stabilize, click or tap the Force meter and choose Zero. The readings for the sensor should be close to zero.

BATTERY TROUBLESHOOTING
If the sensor can be turned on when connected by USB but not when disconnected from USB, it is likely that the battery just needs to be charged. In this case, charge the sensor for several hours and try again. If, however, the sensor won’t turn on regardless of whether the USB cable is connected or not, and you are confident that the USB cable is good by having tested it on another sensor, then the battery has likely reached its end of life and can no longer hold a charge. In this state, the sensor cannot be used even if connected by USB, so the battery will need to be replaced. The rechargeable battery in this sensor is covered by a one year warranty but should last two to five years in typical use. Note that if the battery is less than one year old and the sensor cannot be turned on even when connected by a working USB cable, another possibility is that the USB port is bad. In this case, contact Vernier technical support for assistance.
