Still baffled.Does the test line have to be darker than the control line for a true positive or can it be the same color as the control line?

the instructions state a true positive is the same color as the control linebut on the day I was sure I was ovulating mine was a little darker

Same color. I like to take more then the standard number, and you can see it start to get darker the days before. As soon as it gets to the same color it is a positive.

I dont even think its going to be the exact same color. It's just that the test line will be really prominent. I just happened to be ovulating today and I took a photo of it. I have confirmed it with clearblue ovulation kit as well, so I am definitely ovulating. Hopefully this link works. If it doesn't, copy paste it. It's a photo of my test indicating I am ovulating. http://imgur.com/XeSMMP5

for ovulation they must be the same color or the test line must be darker. I always have 2 lines to, but a positive was obvious when I finally got one :)

The test kit will turn green in the presence of coilform, which means you need to treat your well. The black light is needed to reveal e-coli, but if the sample turns green why bother?

You may initially have only the control line, then for a few days you may have the control line and a faint line (this just means continue testing) Until your second line is AS dark or DARKER than the control line. You do not have a positive test UNTIL the two lines are at least the same color. The instructions inside the box should have covered all this info.

I really havn't had the unit long enough to know, have you given any thought to the fact that most pc moniters often give different color values than in the original input ????

All the tests are based on color . For the lead test, it's a line indicator.

I was looking online, and from my understanding, the pH won't be accurate, and the colors on the color cards won't be accurate, so you will not be able to interpret the readings, but the test results should be the same. Here's one forum that I looked at that can give you more detail:http://www.fishlore.com/fishforum/test-kits/41915-use-sw-master-kit-fw.html

Thanks, i'll check for the switch on the back tonight. i'm sure the polarity is correct, red to lead (+) and black to ground (-) right?

Sorry, I did not post any images so I wouldn't know how to tell one from the other in the images. If C is for color I know mine is in color and not monotone.

Take a multimeter and measure the DC voltage across the hot lead and ground for both lights. If voltage is same then brightness should be same. If voltage is different you need to trouble-shoot the source of the voltage drop. It could be a corroded ground connection or it could be a poor hot wire connection. I did not use the blue snap-on connectors provided by the OEM. I used the grey twist-on connectors and sealed the ends with marine grade RTV silicone. I suspect you have a bad ground. Pull off the light and take a wire brush to the mounting holes. Make sure you have no paint which is interfering with the ground connection.

Not 100% sure. There might be some traces present if line is faint. When I tested it the lines were very strong lines.

For pregnancy test, even a faint second line is positive. For ovulation tests, the line must match the control line. Congratulations!

If you haven't noticed, it has the text in two directions. The test light should be on the bottom right corner, but there could be applications where you would need to reverse the direction (i.e., ceiling mounted).

Hold on here for those 2 answers.. There will ALWAYS be a test line and a control line no matter what time of the month you take the test. The control line will be dark. A negative ovulation test will have a dark control line, and a light test line. Because you always have LH in your system. When you are having an LH surge (ovulation) it will have a dark control line, and the test line will be just as dark if not darker then the control line.

Intermittent faults trigger the wiring path lights and they stay in the "faulted" state until you press the reset button. So if a short across two cable conductors presents itself to the tester while testing, another LED indicator will light up in addition to the correct cable connection path LED's, indicating not only the correct cable path but also the "short" (multiple paths indicated). The LED's stay that way until the reset button is pressed. Note that there may be additional erroneous LED's lit when each cable is first connected to the tester, so each time you insert a cable for testing you should press the reset button to ensure a clean test start.

I haven't had a chance to test the tester out. There are sites on the internet you can check on and I tried to find some instructions on this - sorry.

My strip were colored also. They do work. It is like the red ph liquid tester that only changes color when ph lower than 7.8 is present.
