ESR02 pro Digital Component ESR Meter Multi Function Tester
Product Details:
The Digital Component ESR Meter Multi-function Tester Model
ESR02 pro is a versatile device designed for testing electronic
components. It is equipped with various functions and features to
provide accurate and reliable results.
Function Testing:
The ESR02 pro can perform a wide range of tests on electronic
components. It is capable of measuring the Equivalent Series
Resistance (ESR) of capacitors, making it ideal for troubleshooting
and diagnosing faulty components. Additionally, it can test SMD
devices, electrolytic capacitors, and discharge capacitors.
Usage Instructions:
- Power ON: Before using the ESR02 pro, press
the POWER/TEST button to turn on the device. - Test: To start a test, press the POWER/TEST
button. The meter will automatically recognize the pin’s function
and layout on the screen, regardless of the pin sequence. - Power OFF: The ESR02 pro will automatically
power down if there is no button operation within 20 seconds. - Test Socket: The device is equipped with three
test sockets: SMD socket, plug-in devices socket, and probe socket.
The ports 1, 2, and 3 of each socket are the same and connected
internally. - SMD Device Test: To test SMD devices, you can
use either the SMD socket or the probe. When using the SMD socket,
apply some pressure on the device for better connection. - Electrolytic Capacitor Discharge: The ESR02
pro supports the discharge of electrolytic capacitors with a
maximum capacity of 2000uF/50V. It has an internal 1K/1W resistor
for discharge, and the discharge time should be at least 2 seconds.
For capacitors with a higher capacity, it is recommended to use an
external discharger. - Discharge Function: The discharge function is
standalone and does not require the device to be powered on or any
button to be pressed.

Function Testing:
Usage Instructions:
a. Power ON: Press “POWER/TEST” button before using. b. Test: Press “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. c. Power OFF: Automatically power down if no button operation in 20 seconds. d. Test Socket: With 3 test sockets, SMD socket, Plug-in devices socket and Probe socket. The port 1,
2, 3 of each socket are the same, they are connected internal. e. SMD Device Test: Test via SMD socket or probe. While using SMD socket, put some pressure on
device for better connection.
f. Electrolytic Capacitor Discharge Support max 2000uF/50V capacitor discharge with the internal 1K/1W resistor, and discharge of 2 seconds at least. Use external discharger while the capacity is higher. Discharge is standalone function, no need to power on or press button.
g. 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, return to transistor test. Frequency: reserved. f-Generator: with the button press can select different frequencies output from T2 (Test Port 2), and T1, T3 will be the reference ground. Frequencies selectable from 1 Hz to 2 MHz, amplitude is 5V. 10-bit PWM: Generates a 7.8KHz frequency with selectable pulse width at the 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 33to 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 connection them to the tester. Power down the equipment if test components mounted in a circuit. If using DC supply, please choose DC 9V-12V adapter (including 9V and 12V). When the battery power is under 6V, please replace a new one.
Calibration:
Short T1, T2, T3 to one, then press button. When LCD shows “Selftest mode.. ?”, press 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”.
