ASSEMBLY GUIDE
M162 LCR Meter Diy Kit
| MODEL | M162 |
|---|---|
| PCB VERSION | MAIN: 109-16202-005 |
ANALOG: 109-16201-00F
FIRMWARE| 113-16202-060
Getting Started
TEST THE MAIN BOARD
-
Connect the USB Cable to the Micro-USB port on the Main Board and a USB power source.
-
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 into a state similar to the below illustration. -
The values of the numbers are random. Please ignore them and just ensure the display is normal.
(PCB
109-16202-00B shown)
If your M162 main board does not power up, or powers up with a blank screen,
please contact us at [email protected].
Do not solder any parts onto the board if you encounter any issues as this
will void the warranty.
REQUIRED TOOLS
- 25W Soldering Iron
- Soldering Wire (Rosin-core Recommended)
- Digital Multimeter
- Screwdriver – Philips #1
- Flush (wire) cutter
- Tweezers
- Micro-USB power cable

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 to identify the resistor values.
SLIDE SWITCH
- SW4 SK-22D03T
CAPACITORS
- C9, C10, C11, C12, C13
| 100μF, 16V
---|---
Ensure the polarity of the capacitors are installed correctly. The positive pole goes into the holes of the square pads.
| CONNECTOR (optional) | CHARGER BOARD (optional) |

board (with 5×1 strip pin header)
CLOSE JP1
( Note: skip this step if the battery charger board is installed.)
- JP1
Verify Voltages
- Apply 5V power supply via the micro-USB connector on the analog board.
- Spot check the voltages on the board at the test points labeled to ensure they measure to the voltages in the chart below.
REFERENCE
| Test Points | Voltage |
|---|---|
| Min | Typical |
| V+ | 3.60V |
| VS+ | 3.60V |
| AV+ | 310V |
| V- | |
| VS- | |
| AV- | -2.20V |
| V1 | |
| V2 | |
| V3 | |
| V4 | 1.40V |
Quick Test
-
Attach the main board to the analog board.
-
Apply power supply via the micro-USB connector on the analog board and slide the power switch to ON position.
-
Once the device starts up, hold down RCL button to bring up the menu. Select the “Default” option to set all the parameters to their default values
-
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 of the meter. Further confirmation is required.
Enclosure Assembly
-
Identify the ends of the standoffs.
-
Assemble the two side pieces and back piece. Ensure the standoffs are at the correct orientation.
-
Insert the assembled main board-analog board with the analog board fitted into the standoff slots near the bottom ends.
-
Assemble the front piece. Ensure the standoffs are at the corret orientation.
-
Assemble the top and bottom pieces with screws. Remember to attach the 3 caps to the pushbuttons before securing the top piece.
-
This is how your M126 LCR Meter should look once enclosure assembly is complete:
