Description:
Product categories: Digital Transistor Tester
Parameters:
Resistance: 0-50M. Resolution: 0.01.
Capacitance: 25pf-100mf. Resolution: 1pf.
Inductance: 0.01mH-20H. Resolution: 0.01mH.
Measuring capacitance ESR resolution: 0.01_
Things to note:
Before testing the capacitor, be sure to discharge it, otherwise it may damage the internal circuit.
If using DC supply, please select DC 9V-12V adapter (including 9V and 12V).
Can be powered by a 9V 6LR61 battery (not included), when the battery power is under 6V, please replace a new one.
How to use instructions:
Push "POWER/TEST" to power on and start a test, multiple measurements can be repeated by this key, auto power off 20 seconds after measurement.
Provide three kinds of sockets, each socket pin 1, pin 2 and pin 3 are connected.
There is a table "typical ESR value of electrolytic capacitor" at the back, it is for guiding only, these are typical values for standard grade electrolytic capacitor at room temperature.
Calibration:
Short the test pin 1, 2, 3 together and push "POWER / TEST" button, then the screen prompts to enter calibration, push the button again within 2 seconds to confirm. Few seconds latter the screen prompts to release pin 1, 2, 3, release them and wait for calibration finish.
Packing:
1 x ESR02 PRO Digital Transistor Tester
1 x English User Manual
1*Test clip
1*packing box
The different screens can cause the color of the item in the image to be a little different from the actual one. The allowed measurement error is +/- 1-3 cm.
