My partner and I are doing the Electrolyte challenge that we found on the science buddies website. The experiment says to set our multimeter to 200 milliamps and we did for both orange juice and water but we keep getting the same reading. "1 ." What does this mean and how do we fix it? Please help soon because this is due on Wednesday the 12th of February.

eckeizeredwards - Possibly a setup problem with your meter. Are your probes in the proper sockets? The BLACK probe in the COM socket and the RED probe in the V-Ω-mA socket. Make sure you are not using the 10 Amp socket. Is your meter set properly to mADC, or milliamps DC? Is your battery fresh and your sensor coil not shorted out? Check your setup for these common errors. Let us know if the problem persists. Often a single digit "1" without other digits is a sign of an 'over-range' measurement.
