操作
按“ On/Menu ”键开机，仪表进入设定模式
可见到各步骤
1. 仪表信号
2. 软件版本
3. 共 25 秒仪表初始化倒计时
4. 自动按仪表所处环境进行调零（仪表务必处于干净无污染环境）
5. 自动测试可燃气体泄漏检测探头
然后进入仪表可用状态
如在上述自检过程中出现任何错误，请参照后面故障分析部分
按“ N/ ▼”按键可以开闭背景灯
虽然仪表自检时已进行了自动调零，但仍可随时按下‘ Y/ ▲ /zero ’键手动调零，直到下面图形出现
（调零时仪表务必处于干净无污染环境）
要关机，按“ On/Menu ”键不放，直到听到仪表蜂鸣声。

查漏模式
TPI-775 还可用于可燃气体泄漏检测追踪
1 反时针旋转拨盘直到听到“ dida ”声，
2 将探头接近泄漏区直到声音加速，然后顺时针旋转拨盘使声音减速，
3 重复步骤 2 直到查到泄漏点
4 如果声音停止，泄漏指示减低，说明已远离泄漏点，应按相反方向继续查找漏源
一氧化碳检测
按“ On/Menu ”键。每按“ On/Menu ”键一次，将使你进入下一个屏幕
记录最大读数
按 ‘ Y/ ▲ /zero ’键 5 秒可以将最大值清零。

1 anti clockwise rotary dial until I heard the sound of"Dida",
2 the probe near the leakage area until the sound speed,then clockwise rotary dial to make the sound speed,
3 repeat step 2 until to check the leak
4 if the sound stopped, indicating reduced leakage, that have been away from the leak point, should be in the opposite direction to locate leakage source
The detection of carbon monoxide
Press "On/Menu" key. Each press "On/Menu" key once,will allow you to enter the next screen
