1.3 電源オプション

The signal generator offers flexible power supply methods:

• External 24VDC Terminal: Connect a 24VDC power source to the designated terminals.
• USBタイプC: Use the provided USB Type-C cable to connect to a power adapter or computer.
• Rechargeable Li Battery: The device supports an internal rechargeable lithium battery (not included). When a battery is installed, it can be charged via USB Type-C or external 24VDC while in use.

1.4接続図

Refer to the following diagram for proper terminal connections. Terminal numbers are read from left to right (1-9).

図1.4: Terminal Connection Diagram.

• GND（1）： Power supply negative (input). This is the same as 9-GND and can be arbitrarily connected.
• 24V（2）: Power supply positive (input). External power input to power or charge the meter.
• mA i (3): Current signal input positive.
• Vi (4): 巻tage signal input positive.
• LP+ (5): EXT 24V input (passive mode).
• mA o (6): Current signal output positive. The current output is commonly used in active mode. The output of the meter 6-mAo 9-GND corresponds to positive and negative current input of the PLC.
• Vo (7): 巻tage signal output positive. The voltage出力 7-Vo 9-GND corresponds to the positive and negative voltage input of the PLC, or it can be measured directly with a multimeter.
• PWM (8): PWM output positive.
• GND（9）： Signal common ground (internal connect to ①-GND).

Current Sink Two-Wire Output: 接続する 24V + に 5-LP+ terminal of the meter head, and output from the 6-mAo terminal to control the current of the external 24V. The meter head is equivalent to a variable resistor, so it is called passive mode. Direct measurement cannot detect the current, and it can be directly replaced with a passive two-wire pressure/temperature sensor, etc.

2. 操作手順

2.1 ユーザーインターフェースとディスプレイ

The device features a 2.0-inch TFT color screen (320x240) that displays all values clearly on one screen. It supports both Chinese and English interface switching. The large digital encoder knob allows for easy and precise adjustments.

2.2 DCVol。tageと電流出力

• 巻tage DC Analog Output Range: ±12V (with short circuit protection).
• Current DC Analog Output Range: 0-24mA (short circuit protected).
• 出力調整: Users can freely set the output range, such as 0-20mA, 4-20mA, 0-10V, 0-5V, etc. The corresponding engineering display values can also be set.

2.3 PWM Pulse Square Wave Output

• 調整可能な周波数: 1-150kHz。
• Adjustable Duty Cycle: 0～100%。
• 高いレベル： 5V。
• 応用： PWM pulse output high level is 5V, low level is 0V. It can directly drive buzzers, LEDs, optocouplers, etc., or connect to 12V/24V systems through external level conversion modules.

2.4 Input Measurement

• 巻tage 測定範囲: ±50V。
• 電流測定範囲: ±50mA.

3. メンテナンス

To ensure the longevity and optimal performance of your Luqeeg Signal Generator, follow these maintenance guidelines:

• クリーニング： Use a soft, dry cloth to clean the device. Avoid using abrasive cleaners or solvents, which can damage the casing または画面。
• ストレージ： デバイスは、直射日光、極端な温度、高湿度を避け、涼しく乾燥した場所に保管してください。
• 取り扱い： Handle the device with care to prevent physical damage. Avoid dropping it or exposing it to strong impacts.
• Battery Care (if installed): If using a rechargeable Li battery, ensure it is charged regularly, even if not in frequent use, to maintain battery health. Do not expose the battery to extreme heat or puncture it.
• 保護フィルム: The surface protective film of the sticker can be peeled off for clearer viewing。

4。 トラブルシューティング

This section addresses common issues you might encounter with your signal generator.

• デバイスの電源が入っていない:
  • 電源スイッチが「オン」の位置にあるかどうかを確認します。
  • Ensure the USB Type-C cable is securely connected and the power source is active.
  • If using external 24VDC, verify the power supply is connected correctly to the terminals and is providing the correct voltage.
  • If using a rechargeable battery, ensure it is charged.
• 出力信号なし:
  • Verify that the output parameters (voltage, current, PWM frequency, duty cycle) are set correctly on the display.
  • Check all connections to the output terminals for proper contact.
  • デバイスの電源がオンになっていて機能していることを確認します。
• Incorrect Output Readings:
  • Confirm that the measurement range is appropriate for the signal being measured.
  • Check the calibration settings if custom ranges have been configured.
  • すべての接続が安全であり、干渉がないことを確認してください。
• PWM Output Compatibility:

  注記： The PWM output of this device is not suitable for 12V or 2V systems, as 5V is regarded as a low level in these systems. For such applications, an external level conversion module is required.
