Current Probe (DCP-BTA)
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 in series with a known resistance. Use a voltage probe or voltmeter to measure the voltage of the supply. Compare the measured current against the current calculated from Ohms Law. We recommend a battery for this test, since some DC power supplies may not deliver clean DC voltage.

CALIBRATION
-Calibrate? No. The probe is set to match the stored calibration before shipping.
-If you choose to calibrate the probe, conduct a two-point calibration using two known currents.
-You may also zero the probe by shorting out the leads and then choosing the Zero option in the data collection program. If you zero the probe, it will adjust the calibration offset but does not adjust the calibration gain.
