CALIBRATING THE TESTER
Before you can start testing components, you will have to calibrate the tester. What you'll
need is a capacitor with a capacity between 100nF and 20µF.
Then follow the calibration procedure below:
1. Connect the 3 probes together.
2. Press the button on the tester and immediately press it again if you see "Selftest mode"
on the screen. If successful, you should see "R0=".
3. When you "isolate Probes" appears on the screen, disconnect all the probes.
4. When you see "1 -||-3 > 100nF" appear on the screen, connect the capacitor to probes 1
and 3.
5. After a while, the calibration should end with success.
CONNECTING A COMPONENT
Connecting a component is easy; simply connect the leads of a component to the
connectors. The order/polarity doesn't matter because the tester will figure this out on its
own.
When testing a component, make sure that you do not touch the component during the test
and that it is placed on a non-conductive pad.
EXTRA FEATURES
You can access the extra features by long pressing the button to enter the menu.
f-Generator
By using the additional "f-Generator" (frequency generator) function, the selectable
frequencies can be
switched with key presses. With a long key press (> 0.8s) you will stop the frequency
generator and
return to the function menu.
10-bit PWM
The additional "10-bit PWM" (Pulse Width Modulation) function generates a fixed
frequency with
selectable pulse width at the pin TP2. With a short key press (< 0.5s) the pulse width is
increased by 1%, with a longer key press the pulse width is increased by 10%. If 99%
is overstepped, 100% is subtracted from the result. You can exit this mode with a very long
key press (> 1.3s).
