ASSEMBLY GUIDE

1 Getting Started

1. Test the Main Board: Connect the USB Cable to the Micro-USB port on the Main Board and a USB power source.
2. Ensure your M162 main board boots up correctly. When powered on, the LED (D1) will blink twice. The display will then go through two splash screens and enter a state similar to the illustration. The values shown on the display are random and can be ignored; ensure the display is normal.
3. Apply power.

Troubleshooting: If your M162 main board does not power up, or powers up with a blank screen, please contact support@jyetech.com. Do not solder any parts onto the board if you encounter any issues, as this will void the warranty.

2 Main Board Assembly

Required Tools:

• 1: 25W Soldering Iron
• 2: Soldering Wire (Rosin-core Recommended)
• 3: Digital Multimeter
• 4: Screwdriver - Philips #1
• 5: Flush (wire) cutter
• 6: Tweezers
• 7: Micro-USB power cable

Components:

Strip Sockets:

• J4: 12x1 strip socket

Pin Headers:

• J5: 12x1 pin header
• J8, J9: 2x1 pin header

Push Buttons:

• SW1, SW2, SW3: 6.2x6.2x9.5 mm tact switch

Contact Arms:

• J13, J14, J15, J16, J17, J18: Provided with the kit

3 Analog Board Assembly

Resistors:

• R1, R2, R4, R5, R8, R11, R15, R16, R19, R20: 1kΩ
• R3, R12: 100Ω
• R6: 560Ω
• R10: 100kΩ
• R14: 5.1kΩ
• R17, R21, R23, R24: 6.2kΩ
• R18: 47Ω
• R27, R28: 10Ω

Use a multimeter or a resistor color code chart to identify the resistor values.

Capacitors:

• C9, C10, C11, C12, C13: 100μF, 16V

Ensure the polarity of the capacitors is installed correctly. The positive pole goes into the holes of the square pads.

Other Components:

• SW4: SK-22D037 slide switch
• J11: XH2.54 2-pin header (optional)
• BOB1: JYE118 battery charger breakout board (with 5x1 strip pin header) (optional)

Close JP1: Short the two pads with solder. (Note: skip this step if the battery charger board is installed.)

4 Verify Voltages

1. Apply 5V power supply via the micro-USB connector on the analog board.
2. Spot check the voltages on the board at the test points labeled to ensure they measure to the voltages in the chart below. Use the GND connection for your multimeter's negative probe.

3. Once the device starts up, hold down the RCL button to bring up the menu. Select the "Default" option to set all parameters to their default values.
4. Test measurement with the provided resistors (1Ω & 1MΩ), capacitor (0.1µF), and inductor (1mH), or with your own components. Note: The provided resistors are 1% tolerance. The capacitor and inductor tolerance can be 10% or higher. If the measured values are away from their labeled value, they might not reflect a problem with the meter. Further confirmation is required.

5 Quick Test

1. Attach the main board to the analog board.
2. Apply power supply via the micro-USB connector on the analog board and slide the power switch to the ON position.
3. Insert the assembled main board-analog board with the analog board fitted into the standoff slots near the bottom ends.
4. Assemble the front piece. Ensure the standoffs are at the correct orientation.

6 Enclosure Assembly

1. Identify the ends of the standoffs: Longer, Shorter, Bend.
2. Assemble the two side pieces and back piece. Ensure the standoffs are at the correct orientation.
3. Assemble the top and bottom pieces with screws. Remember to attach the 3 caps to the pushbuttons before securing the top piece.
4. Assemble the front piece. Ensure the standoffs are at the correct orientation.

This is how your M162 LCR Meter should look once enclosure assembly is complete.
