Specifications: 1. Overview: HR530 is a small ESR milliohm meter, which can measure the ESR value of electrolytic capacitors and (measure battery internal resistance and battery voltage), as well as resistance milliohm meters. It is easy to use.
2. Product application: ¡Ü Measure ESR value of electrolytic capacitor; ¡Ü Measure resistance value; ¡Ü Measure battery internal resistance and battery voltage value; 3. Technical parameter table: No. Item Parameter Unit Remarks 1 Measuring resistance range 0.001¢¦120 Ω 2 Measuring resistance resolution 1 mΩ 3 Measuring battery voltage 0¢¦25 VDC 4 Measuring battery voltage resolution 0.01 VDC 5 Output measuring frequency 100K Hz 6 Working Voltage 7¢¦12 VDC 7 Working current <50 mA 8 Working temperature -40¡É¢¦65¡É Celsius 9 Storage temperature -40¡É¢¦65¡É Celsius 10 Dimensions 57*45*20 mm L×W×H 4. Interface description and related operations P1 wiring definition: No. Symbol Meaning 1 VDD module's power supply positive pole (7V~12V) 2 GND module's power supply negative pole P2 wiring definition: serial number symbol meaning
4. Button Description FUN: Set and change the ESR value of the measured capacitor or the internal resistance and voltage of the battery. Mes/Cal: Calibration (short-circuit measurement line calibration)
Note: The display is backlit, standard LCD1602 interface. Recently, some customers often ask these questions, and explain: Question: This HR530 meter measures the capacitor ESR value, can it also measure the capacitor capacity? HR530 is a meter for measuring capacitance ESR value, it is designed to measure capacitance ESR value, but it cannot measure capacitance. In the LCD1602 display shown in the figure below, "10000.0uF" is displayed in the lower line of letters. This value is not the capacity value of the capacitor under test. This value is just a reference value. Please refer to the ESR capacitor-resistance reference table for details. ![](https://img.alicdn.com/imgextra/i2/94736924/T2u3iqXDXXXXXXXXXX_!!94736924.jpg)
