<p><b>New page</b></p><div>== Build ==<br />
Attach all the parts from the lower to higher, attach all the resistors and inductors firstly, be careful of the value, then the capacitors and rest items.<br /><br />
Check all the values of resistors:<br /><br />

<br />
Check all the details below and make it wrong.<br />
* The direction of electrolytic capacitor<br />
* The direction of two titanium capacitors<br />
* The direction of push buttons, marked as vertical line "|" should towards to bottom<br />

=== Debugging ===<br />
After build, do not attach the IC and 1602 LCD first, connect your multimeter at the socket pin 7 and 22, voltage value should be 5V, then it is correct.<br />
<br />
== Calibration ==<br />
* After Build, adjust the potentiometer on the top for the brightness of the LCD<br />
* Connect your own multimeter to the pin marked as "TP", and adjust potentiometer 5K near it until the multimeter show the voltage and 3.16V <br />
[[File:Build CIM 07.JPG|thumbnail]]<br />
* After these two steps, calibration is done.<br />
And double check:<br />
* Check IC socket pin 7 and 22 (VCC and GND), when 9V input is provided, the volt here should be 5V<br />
* setOK and should show, F=430684hz, 1842.2pf, 74-76uf, slightly difference will be fine.<br />
<br />
== Usage ==<br />
=== Start and calibration ===<br />
* This normally takes one minute, wait until you see the screen info below:<br />, normally value should be nearly 0 pf when NC connect<br />
* around 74-76uH inductor value is fine.<br />
* Do not connect anything after you see this message on the LCD<br />
* Now press the button to switch to different measurement function<br />

=== Testing Capacitor ===<br />
Attach the capacitor on "C" and middle "COM"<br /><br />
