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.<\/li>\n<\/ul>\n<ul class=\"wp-block-list\">\n<li><b>Secondary Test:<\/b> 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.<br \/><a href=\"\/product\/replacement-fuse-for-high-current-sensor\/\">Replacement Fuse for High Current Sensor<\/a> (<nobr>FUSE-HCS<\/nobr>)<\/li>\n<\/ul>\n<div style=\"height:20px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n<h3 class=\"wp-block-heading\">Additional Troubleshooting<\/h3>\n<ul class=\"wp-block-list\">\n<li><a href=\"\/til\/2765\/\">Why is my High Current Sensor is giving inconsistent readings?<\/a><\/li>\n<li><a href=\"\/til\/1973\/\">How do I measure currents larger than 0.6 amperes?<\/a><\/li>\n<li><a href=\"\/til\/2765\/\">Why is my High Current Sensor is giving inconsistent readings?<\/a><\/li>\n<li><a href=\"\/til\/1139\/\">How can I measure currents outside the range of the Vernier Current Probe?<\/a><\/li>\n<\/ul>\n<div style=\"height:20px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n<h3 class=\"wp-block-heading\">Specifications<\/h3>\n<ul class=\"wp-block-list\">\n<li>Resolution<br \/>\u26ac 12-bit: 4.9 mA<br \/>\u26ac 13-bit: 2.4 mA<\/li>\n<li>Sensor range: \u00b110 A<\/li>\n<li>Maximum voltage input: \u00b140 V<\/li>\n<li>Replaceable fuse Current: 10 A<\/li>\n<li>Calibration equation<br \/>\u26ac slope = 4.51 A\/V<br \/>\u26ac intercept = -11.31 A<\/li>\n<\/ul>\n<div style=\"height:20px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n<h3 class=\"wp-block-heading\">Calibration<\/h3>\n<p>Calibrating the sensor is usually not needed prior to use.
