Really? so you can't understand the meaning of using electronic methods instead of bogus experimenting? Let me translate it into a short statement that maybe you can understand more easily:
It looks like you lied to us again about measuring voltage inside the Ranger Tell. You don't have a clue of how to use a voltmeter to make millivolt readings, as you followed the misinformation shown on the Ranger Tell page rather than showing us any readings you want us to believe you made inside the enclosure.
Max is correct. The calculator does produce small voltages.

You are correct. The calculator does use current to light up the digits in the LCD display. This is easy to measure on a calculator. Simply wind a small coil around a steel core using the same wire as you use to make a detector search coil. You can make this coil the size of a coin wrapped around a steel bolt, or up to the size of the calculator. Connect the ends to an oscilloscope and scan the calculator for magnetic components of a field. You will see the voltages inside the calculator, you will see some in the audio range that you could actually hear if you connected the coil ends to an audio amplifier. And you would also hear sounds change if you start to press buttons. You will find you can also measure some of the internal calculator operations with other odd tools instead of a coil. Maybe connecting the voltmeter to an old circuit board with some components on it placed near the calculator will give a reading, or a coat hanger wire with a transistor soldered to the end.
Inside the calculator
Whether the power comes from a battery or solar panel, a small amount is used to power each segment of the display as well as the processor and controllers in the main processor chip. While the statement that the calculator frequency varies is false, there are several fixed frequencies inside a calculator beginning with the main clock, and then lower frequencies used to drive the display and scan the keypad to detect buttons being pressed, and a few other functions. These frequencies don't change. If a number is entered into the calculator, the only change involves shift registers storing the numbers entered, and the display driver electronics sending impulses to the display segments. The frequency of the display driver does not change. Only the power sent to segments changes as different segments are switched on at this constant frequency.
Reading the rise and fall of these small switching circuits by using a coil outside the calculator is enhanced by a grid of keypad conductors which carry the low-frequency keypad scan strobe to a planar array that almost has the form of a kind of antenna printed on the circuit board. In addition, the voltage impulses sent to the LCD will show a pulse train with varying lengths and durations within the same frequency, in order to select which segments to light up. This pulse train is carried through a short ribbon cable usually. While these are the two most likely places to see a low frequency component perhaps in the audio range, there are other higher frequency components that happen only momentarily while the calculator is processing a user input or making a calculation. In the quiescent state, the only active circuits are the clock refreshing the memory, the keypad strobe, and the display driver. None of these frequencies change. But they can be measured on an oscilloscope or heard a sensitive audio amp.
How to promote bad science
Now if you wanted to use the voltage transients that are generated by a calculator to collect lots of money, or to prove some stupid concept of pseudoscience, first you would need to find a source of people who have little knowledge of the workings in a calculator, and don't have much experience using test equipment. Then direct them to use a millivolt meter in a way prone to electrical interference and use sloppy testing methods that are guaranteed to produce errors. This will make a good blend between the errors and calculator measurements. By using this technique, you may be able to convince a non-technical person that the calculator is finding gold, or that the readings prove you can extract free energy from a vacum. You might even convince him to send you a large sum of money to buy your calculator apparatus.
Think I am wrong? Think the Ranger Tell really does signal the presence of gold in the distance? Then try the experiment I described in the post above to remove the fake readings, and see for yourself.
