Diagnosis

怎样判断灯条状态How to check LED strips

• 同型号、同规格灯条在相近亮度下，测试电压应大致接近。
• 同组灯条测试电压相差超过约 3V 时，该灯条可能存在异常。
• 不亮时先交换正负极并检查接触，再与同型号良品对比。
• 维修判断只需点亮即可，不要长时间调到过亮。

• Matching strips should show similar voltage at similar brightness.
• A difference above roughly 3V within a matching set may indicate a fault.
• If dark, reverse polarity and check contact before comparing with a known-good strip.
• Use only enough brightness for diagnosis; avoid prolonged over-bright testing.

Safety

高压输出安全注意High-voltage safety

严禁双手分别触摸正、负输出端。半隔离 / 电容限流只能限制电流，不能消除触电风险。

Never touch the positive and negative outputs with separate hands. Capacitive current limiting does not eliminate shock risk.

• 只握表笔绝缘柄，勿湿手、赤脚操作。
• 不用时关闭电源并拔下插头，正负表笔分开放置。
• 建议约每使用 2 小时，拔掉电源休息 5 分钟。
• 异常发热、异味或损坏时立即停用，禁止自行拆机。

• Hold insulated grips only; never operate with wet hands or bare feet.
• Switch off and unplug after use; store probes separately.
• After about two hours, unplug and rest the unit for five minutes.
• Stop immediately if overheating, odor or damage occurs; do not open the enclosure.
