New battery internal resistance tester with ESR measurement function

I. Overview:
HR530 is a small ESR milliohm meter, which can measure the ESR value of electrolytic capacitors (measure the battery internal resistance and battery voltage value), and can also measure the resistance milliohm meter, easy to use.
 
Product application:
● Measure the ESR value of electrolytic capacitors;
● Measure the resistance value;
● Measure battery internal resistance and battery voltage value;

Third, the technical parameter table:

Fourth, the interface description and related operations
P1 wiring definition:
No. Symbol Meaning
1 VDD Positive power supply of the module (7V ~ 12V)
2 GND Negative power supply of the module

P2 wiring definition:
No. Symbol Meaning
1 TP + connected to the measuring (battery connected to the positive electrode)
2 TP- connected to the measurement (battery connected to the negative electrode)

Fourth, the key description
FUN: Set the ESR value of the measurement capacitor or the internal resistance and voltage of the battery.
Mes / Cal: Calibration (short-circuit measurement line calibration)

Note: The display has backlight and standard LCD1602 interface.

Recently, I often encountered some customers asking these questions, and explained:

Question: This HR530 meter measures the ESR value of the capacitor. Can it also measure the capacitance?

HR530It is a table for measuring the ESR value of a capacitor. It is specifically designed to measure the ESR value of a capacitor.

In the LCD1602 display screen below, the letter "10000.0uF" in the lower line shows that this value is not the capacity value of the capacitor under test. This value is only a reference value. For details, please checkESR capacitor-resistance reference table.

ESR capacitor-resistance reference table:
