Description:

The PLJ-091OLED-L1 is a cost-effective OLED display pen-style frequency counter featuring a compact, portable design. This product measures signals requiring high frequency accuracy, such as verifying the precision of microcontroller system crystal oscillators and assessing the reliability of communication port output timing.

Display Digit Specifications:

0.91-inch OLED display shows up to 8 digits. For signals exceeding 100MHz in MHz or KHz mode, the leading digit “1” is omitted. Press K2 to switch units to Hz for full display.

Notes:

1. For signal ground connections, use only the shielding layer of shielded cables; do not use the inner conductor.

2. Do not use fast-charging adapters, as they may output voltages exceeding 5V.

Troubleshooting:

1. Why does the frequency reading fluctuate?

Answer: First, ensure the input signal quality (strength, stability, etc.) meets the minimum requirements of the frequency tester. Additionally, verify power supply quality—ripples should not be excessive. Alternatively, adjust sensitivity via the trimming resistor.

2. Why does the reading fluctuate irregularly when no signal is connected?

Answer: This product has high sensitivity and easily detects environmental interference. First, check if the power supply providing electricity to the frequency tester has excessive ripple. Second, inspect for strong signal radiation sources near the frequency tester, such as computers, fluorescent lights, or switching power supplies. The display should read zero in the absence of strong signal interference sources.
