Have you tested the rain gauge using the calibration procedures on page 21 of the manual? Specifically confirming that the bucket is emptying about every 25 drops. https://www.acurite.com/media/manuals/01536-instructions.pdf

It's not clear what your question is.

If you select current measuring (A or mA) and have the test lead connected to V then you get this alarm. Same thing if you select Voltage measuring and the lead is connected to a current terminal. Check the connections and the selector setting.

Depends on the make of the scales. Check manufacturer.

can the battery be replaced. If so, how? open the cover on the back of the device. this is done by squeezing the cover of the battery sector slightly. then remove the old batteries and replace the new ones (I assume you have the AAA) and put the new ones in keeping with the polarity for the device to work properly and then close the battery compartment cover in reverse order

Sure, I'd be happy to help you recalibrate your Super Pro moisture meter. Here are the steps you can follow:

1. Find a reference sample: You will need a sample of maize that has a known moisture content that is different from the current reading on your moisture meter. You can either purchase a certified reference sample or make your own by drying a sample of maize in an oven or using a moisture analyzer.
2. Adjust the calibration: Turn on your Super Pro moisture meter and press the "calibrate" button. Using the reference sample, adjust the calibration of the moisture meter by adding or subtracting the required percentage points to match the known moisture content of the reference sample. For example, if the reference sample has a moisture content of 14% and your moisture meter is reading 16%, you will need to subtract 2% from the calibration.
3. Verify the calibration: After adjusting the calibration, test the moisture meter again using the reference sample to verify that the readings match the known moisture content. If the readings do not match, adjust the calibration again until you get an accurate reading.
4. Document the calibration: Once you have verified the calibration, document the adjustments you made and the reference sample used for future reference.

It's important to note that different types of maize can have different calibration requirements, so it's a good idea to recalibrate your moisture meter regularly and for different types of maize samples. You can also refer to the manufacturer's instructions for specific calibration procedures for your Super Pro moisture meter.
