High Current Sensor Troubleshooting and FAQs

High Current Sensor, order code HCS-BTA, $79
Specifications and User Guide

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. We recommend a DC battery for this test, since some DC 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 has been included with the sensor. Additional replacements in packs of five can be purchased from Vernier Replacement Fuse for High Current Sensor, order code FUSE-HCS, $5.

SPECIFICATIONS
order code: HCS-BTA
12-bit resolution: 4.9 mA
13-bit resolution: 2.4 mA
Sensor range: +/- 10 A
Maximum voltage input: +/- 40 V
Replaceable fuse Current in amperes: 10A
Calibration equation: slope = 4.51 A/V, intercept = -11.31 A

CALIBRATION
Probably not needed. You may want to zero the sensor through the software. 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.
