Product Overview:
The PLJ-091OLED-L1 is a high-performance pen-style frequency counter featuring an OLED display. Compact and portable, it is designed for precision frequency measurement applications such as testing crystal oscillator accuracy in microcontroller systems and evaluating communication port timing reliability.

Features:
1. Core Technology: Sanjian Studio SJ8K24P-T dedicated chip (100MHz capacity)
2. Premium Build: Acrylic housing + 0.91" blue OLED display
3. High-Precision Reference: KDS VC-TCXO (±2.5ppm stability)
4. Advanced Algorithm: Unique gate control with precision timing (non-interrupt driven)
5. Dual Gate Times: 0.1s/1.0s selectable (10Hz/1Hz resolution)
6. Smart Display Modes: MHz/kHz/Hz unit switching for optimal readability
7. Dual Input Methods: Signal probe needle or IPEX port (high sensitivity)
8. Type-C Powered: 5V operation with low current consumption
9. Auto Memory: Settings preserved after power cycle
10. Applications: MCU crystal oscillator verification,Radio communication equipment testing,Frequency generator calibration,Educational electronics labs

Specification:
- Frequency Range ： 200 Hz – 100 MHz
- Resolution ： 10 Hz (0.1s gate) / 1 Hz (1.0s gate)
- Time Base Stability ： ±2.5 ppm
- Input Impedance ： High Z
- Frequency Reference : 3.000MHz VC-TCXO (KDS)
- Operating Voltage ： DC 4.5–5.5V (5V recommended)
- Current Consumption : ≈30mA @ 5V
- Display : 0.91" OLED (8-digit capacity)
- Connectors : IPEX (RF IN), Type-C (Power)
- Dimensions : 138×18×11mm

Operation Guide:
- Gate Time Selection: Press button to toggle between 0.1s (faster refresh) and 1.0s (higher accuracy)
- Unit Display: Cycle through MHz/kHz/Hz modes for best reading format
- Note: Signals >100MHz show truncated display in MHz/kHz modes - use Hz mode for full resolution

Input Options:
- Use needle probe for direct IC testing
- Use IPEX port for cable connection

Package Included:
1 x Frequency meter
1 x Power connection cable
1 x Signal ground connection line

Setup Guide

1
Identify the pins
Locate VCC (power), GND (ground), and data pins (SDA/SCL for I2C, MOSI/MISO for SPI, or TX/RX for UART). Refer to the pinout diagram on the product page.
2
Wire to your microcontroller
Connect VCC to 3.3V or 5V (check the module spec), GND to GND, and data pins to the appropriate GPIO pins on your Arduino or Raspberry Pi.
3
Install libraries
In Arduino IDE, go to Sketch → Include Library → Manage Libraries and search for the sensor library. Install the recommended version.
4
Upload example sketch
Open File → Examples → [library name] → Basic Example. Upload to your board and open Serial Monitor to view output.
5
Calibrate if needed
Some sensors (temperature, humidity, distance) may need a short warm-up period or calibration. Run the calibration sketch if provided.
