Advantages :

• Fine and High Precision
• Small Size
• Cheap to Build
• Less Components
• AutoRange

Specifications :

• Measure Inductance Range : 0.01uH to 999H
• Supply Voltage Range : 3 to 5V DC
• Currect Consumption : 40mA Max
• Measurement Rate : 3/sec for Lx < 500mH and 1/sec for Lx > 500mH

Program the MCU on PCB

the "J3" Connector is used for Program MCU (STM8S003F3) with ST-LINK Programmer and SWIM Protocol.

J3 Pin Description :

Pin 1 : GND
Pin 2 : SWIM
Pin 3 : RESET (RST)

Note :

Your need Connect Power Supply to J1 for Programming.

Calibration :

Calibration is required before the first use of the device.

• Connect Power Supply to Inductance Meter
• Connect Lx Probes to together
• Press the Inductance Meter Button
