First, an overview :HR530 is a small ESR ohm meter can measure electrolytic capacitor ESR values ( measurement of battery internal resistance of the battery voltage value ) , but also measure the resistance milliohms table to use, simple to use.Second, product applications: measuring electrolytic capacitor ESR values ; Measure the resistance value ; measure battery internal resistance of the battery voltage ;

Third, the technical parameters:No. Item Parameter Unit RemarkA measuring range of 0.001 ~ 120 Ω resistor2 1 mΩ sense resistor differentiate degrees3 measuring battery voltage 0 ~ 25 VDC4 measuring 0.01 VDC battery voltage differentiate degrees5 100K Hz output frequency measurement6 7 ~ 12 VDC operating voltage7 working current <50 mA8 Operating temperature -40 ~ 65 Celsius9 Storage temperature -40 ~ 65 Celsius10 Size 57 * 45 * 20 mm Length X Width X Height

Fourth, the interface description and related operationsP1 wiring definition:No. Symbol Meaning1 VDD positive power module (7V ~ 12V)2 GND negative power module

P2 wiring definition:No. Symbol Meaning1 TP + connected measurement devices ( batteries then positive )2 TP- contact measurement devices ( batteries then negative )

Fourth, KEYSFUN: Let the measured capacitance ESR values or change the battery internal resistance and the voltage .Mes / Cal: calibration ( short-circuit measurement line calibration )

Note: The display has a backlight , standard LCD1602 interface.

Recently often encounter some customers ask these questions , explain:

Problem: TheHR200 table is measured capacitance ESR values , it can not be measured capacitance it?

HR200Is a capacitor ESR meter values , specifically measured capacitance ESR value can not be measured capacitance .

The following diagram LCD1602 display , the following line of letters in the display "10000.0uF", this value is not measured capacitance value , this value is just a reference value. Specific ContrastESR Capacitor - Resistor reference table .

ESR Capacitor - Resistor reference table :

Resistor 22R

Measuring resistance 0.22R

Measuring capacitance 3300uf
