3. はじめに: セットアップ
バッテリーの取り付け
The Fluke 325 requires two AA batteries (included). To install or replace batteries:
- メーターがオフになっていることを確認してください。
- メーターの背面にある電池ボックスを見つけます。
- ドライバーを使用して電池ボックスのカバーを開きます。
- 正しい極性に注意して、単三電池 2 本を挿入します。
- 電池カバーを取り付けて、ネジで固定します。
テストリードの接続
巻の場合tage, resistance, continuity, frequency, temperature, and capacitance measurements, connect the test leads to the appropriate input jacks:
- 黒いテストリード線を COM (共通) ジャックに挿入します。
- Insert the red test lead into the VΩHz jack for most measurements.

4. Operating Your Fluke 325
機能セレクターダイヤル
The large yellow rotary dial on the front of the meter is used to select the desired measurement function. Turn the dial to the appropriate setting for your task.
AC/DC電流測定（Clamp)
AC または DC 電流を測定するには:
- Turn the function dial to the ∼A (AC current) or =A (DC current) position.
- clを開くamp レバーを押すとジョーが開きます。
- Place the jaws around a single conductor. Ensure the jaws are fully closed.
- ディスプレイ上の現在の値を読み取ります。

巻tage測定（AC/DC）
ACまたはDCvolを測定するにはtage:
- Connect the test leads as described in the 'Connecting Test Leads' section.
- Turn the function dial to the ∼V (AC voltage) or =V (DC voltage) 位置。
- テストプローブを回路のポイントに接触させて、tage を測定する必要があります。
- 巻を読むtagディスプレイ上のe値。
抵抗と継続
To measure resistance or check continuity:
- テストリード線を接続します。
- Turn the function dial to the Ω (resistance/continuity) position.
- コンポーネントまたは回路パス全体にテスト プローブを接触させます。
- For resistance, read the value on the display. For continuity, the meter will beep if a continuous path is detected.
Frequency, Temperature, and Capacitance
The Fluke 325 also offers specialized measurements:
- 周波数（Hz）： Select the Hz function to measure the frequency of AC signals.
- 温度（°C/°F）: Use the included temperature probe and select the temperature function to measure temperature.
- キャパシタンス： Select the capacitance function to measure the capacitance of components.
True-RMS Accuracy
The True-RMS feature ensures accurate measurements of AC voltage and current, even when waveforms are distorted or non-sinusoidal. This is crucial for modern electrical systems with non-linear loads.
バックライトディスプレイ
The Fluke 325 features a backlit display for improved visibility in dimly lit environments. Press the backlight button to activate or deactivate the backlight.

5. メンテナンスとケア
クリーニング
To clean the meter, wipe it with a damp 布と中性洗剤で拭いてください。研磨剤や溶剤は使用しないでください。使用前にメーターが完全に乾いていることを確認してください。
バッテリー交換
When the battery indicator appears on the display, replace the batteries as described in the 'Battery Installation' section.
ストレージ
メーターは直射日光や極端な温度を避け、涼しく乾燥した場所に保管してください。長期間保管する場合は、液漏れを防ぐため電池を取り外してください。
6. 一般的な問題のトラブルシューティング
- ディスプレイ/電源なし: 電池の取り付けを確認し、電池が消耗していないことを確認してください。
- 不正確な読み取り: Verify correct function and range selection. Ensure test leads are properly connected and not damaged. For current measurements, ensure the clamp jaws are fully closed around a single conductor.
- 導通ビープ音が動作しない: Check if the function dial is set to continuity and test leads are making good contact.
- 「OL」ディスプレイ： This indicates an overload or out-of-range measurement. Select a higher range or ensure the measured value is within the meter's specifications.
