使用說明書Directions for use
u 儀表正確連接后，接通電源到額定電壓，此時綠色指示燈亮，儀表即處于監(jiān)測狀態(tài)，指針指示值即為電網(wǎng)絕緣電阻值（自檢檔除外）。After the instrument is correctly connected, connect the power supply to the rated voltage, and the green indicator light will be on at this time, the instrument will be in the monitoring state, and the indicator value is the insulation resistance value of the power grid (excluding the self check file).
u 儀表在工作時報警設(shè)定開關(guān)應(yīng)設(shè)置在所選定的報警值位置，具體報警值檔位見背面展示圖。用戶有其他要求時可在訂貨時注明。When the instrument is working, the alarm setting switch shall be set at the selected alarm value position. See the back display diagram for the specific alarm value position. Other requirements of users can be noted when ordering.
u 如需判別儀表工作是否正常時可進行自檢，將儀表后面開關(guān)設(shè)置在自檢檔位，儀表即進行自檢，儀表能進行正常自檢時指針應(yīng)指示在10KΩ位置，同時報警紅燈點亮，報警輸出端有輸出。自檢完畢后必須將儀表恢復(fù)到正常報警檔位上。If it is necessary to judge whether the instrument works normally, self inspection can be carried out. Set the switch at the back of the instrument to the self inspection gear, and the instrument will carry out self inspection. When the instrument can carry out normal self inspection, the pointer shall indicate the position of 10KΩ, and the alarm red light will be on, and the alarm output terminal has output. After the self-test, the instrument must be restored to the normal alarm gear.
