katranji ESR02 pro Digital Component ESR Meter Multi Function Tester
Product Details
Function Testing
Usage Instructions
- Power ON: Press the “POWER/TEST” button before using.
- Test: Press the “POWER/TEST” button to start a test. Regardless of the pin sequence, this meter will recognize the pin’s function and layout on the screen.
- Power OFF: Automatically power down if no button operation in 20 seconds.
- Test Socket: With 3 test sockets, SMD socket, Plug-in devices socket, and Probe socket. The ports 1,2, and 3 of each socket are the same, they are connected internally.
- SMD Device Test: Test via SMD socket or probe. While using an SMD socket, put some pressure on-device for better connection.
f.Electrolytic Capacitor Discharge Support max 2000uF/50V capacitor discharge with the internal1K/1W resistor, and discharge of 2 seconds at least.
- Use an external discharger while the capacity is higher.
- Discharge is a standalone function, no need to power on or press a button.
- Selection Menu: A long button press (>0.5s) will enter the selection menu for additional functions.Short button press to switch different functions and long button press (>0.5s) to enter Submenu.
- Switch off: Long button press to power Off immediately.
- Transistor: exit Selection Menu, and return to the transistor test.
- Frequency: reserved.
- Generator: with the button, the press can select different frequencies output from T2 (Test Port2), and T1, and T3 will be the reference ground. Frequencies are selectable from 1 Hz to 2 MHz, the amplitude is 5V.
- 10-bit PWM: Generates a 7.8KHz frequency with selectable pulse width at pin T2. With a short button press (<0.5s) the pulse width is increased by 1%, with a longer button press (>0.5s,<1.3s) the pulse width is increased by 10%.
- C+EST@TP1:3: It’s a stand-alone capacity measurement with ESR measurement at the test pins T1 and T3.
- Rotary Encoder: Reserved.
- Self-test: Full self-test with calibration.
- Contrast: Contrast value for a graphic display, selectable from 33 to 55.
Note: In selection mode, the Tester will auto power off after 8 minutes without any button press.
Attention
- Always be sure to discharge capacitors before connecting them to the tester.
- Power down the equipment if test components are mounted in a circuit.
- If using a DC supply, please choose a DC 9V-12V adapter (including 9V and 12V).
- When the battery power is under 6V, please replace a new one.
Calibration
- Short T1, T2, and T3 to one, then press the button.
- When LCD shows “Selftest mode.. ?”, press the button within 2 seconds to enter calibration mode, otherwise will come into transistor test mode.
- Tester automatic calibration until LCD shows “isolate Probes!”, then separate T1, T2, and T3.
- Wait a few seconds until LCD shows “Test End”.
