WWH-Battery internal resistance tester ESR capacitor circuit tester

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 Remark 1 measuring range of 0.001 ~ 120 O resistor 2 1 mO sense resistor differentiate degrees 3 measuring battery voltage 0 ~ 25 VDC 4 measuring 0.01 VDC battery voltage differentiate degrees 5 100K Hz output frequency measurement 6 7 ~ 12 VDC operating voltage 7 working current <50 mA 8 Operating temperature -40 °C ~ 65 °C Celsius 9 Storage temperature -40 °C ~ 65 °C Celsius 10 Size 57 * 45 * 20 mm Length X Width X Height Fourth, the interface description and related operations P1 wiring definition: No. Symbol Meaning 1 VDD positive power module (7V ~ 12V) 2 GND negative power module P2 wiring definition: No. Symbol Meaning 1 TP + connected measurement devices (batteries then positive) 2 TP-contact measurement devices (batteries then negative) Five Key Description FUN: 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: The HR200 table is measured capacitance ESR values, it can not be measured capacitance it? HR200 is a meter capacitor ESR 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 Contrast ESR Capacitor - Resistor reference table.
