Troubleshooting
- Primary Test: Plug the probe into an interface and run the data collection program. Use wire leads to connect the probe to a DC supply with a known resistance. Use a voltage probe or voltmeter to measure the voltage. Compare the measured current against the theoretical reading. Note: We recommend a DC battery for this test, since some variable power supplies may not deliver clean DC voltage.
- Secondary Test: The sensor contains a replaceable 10 A fuse. If the sensor stops measuring current, you may need to replace a blown fuse. Turn the sensor over and remove the four screws on the back. The fuse can be seen from the top. Use a small screw driver to remove the fuse. Insert a replacement. One replacement fuse has been included with the sensor. Additional replacements, in packs of five, can be purchased from Vernier.

Calibration
Calibrating the sensor is usually not needed prior to use. You may want to zero the sensor through the software; connect the sensor’s terminals with a single wire/alligator clip first. When measuring currents that are less than 0.6 A, we recommend our Current Sensor (DCP-BTA). If you use HCS-BTA to measure small currents, e.g. less than 1 A, you might want to calibrate the sensor.
