总述
TPI-720b是一种先进的探测仪器可测试可燃气、非可燃气、及有毒气体。
下面是可检测的部分气体
丙酮、酒精(乙醇)、氨气、蒸汽、CO(一氧化碳)、丁烷、汽油、喷气燃料、硫化氢、烟气、工业溶剂
甲烷、油漆稀料、石脑油、丙烷、天然气。甲苯、丁酮
*不可用于测量CO的浓度值因(无数字显示)
操作指南
1. 洁净环境下开机,将开关打倒“ON”位置
2. 电量充足的话绿色灯点亮,预热时红色LED灯闪烁,嘀嗒报警声也会响起,要消除该报警声,将转盘逆时针旋转到底。
3. 要调节“嘀嗒”声速率可用拇指顺时针旋转拨盘直到听到均匀一致的“嘀嗒”声。此时红色LED灯将闪烁
4. 将探头接近怀疑有泄漏的地区直到“嘀嗒”声开始加强,此时轻微反时针旋转拨盘使“嘀嗒”声减弱,然或继续将探头靠近泄漏区域,声音大时再调小速率,直到找到泄漏位置为止。
5. 如果绿色LED灯闪烁,表示需更换电池。
6. 如果环境嘈杂,可以使用耳机(将耳机插入耳机插口)。
7. 如果仪表不工作或故障,请遵循手册后面的工作检查部分进行检查。
更换电池
工作检查
开机并使机器预热1分钟,将探头暴露于已知的气体源比如未点燃的打火机气体(丁烷),接近气源响声应加速,远离气源声速应减慢,否则的话需要更换探头或作进一步维修检查。
注意:本仪器须送到指定维修厂进行维修
更换探头
1. 将仪表关机
2. 取下探头帽
3. 取下旧探头
4. 更换传感器及探头帽
5. 重新开机并进行“工作检查”步骤

Overview
TPI-720b is a kind of advanced detection instrument cantest gas, non combustible gas, and toxic gas.
The following is part of the gas can be detected
Acetone, alcohol (ethanol), ammonia gas, steam, CO(carbon monoxide), butane, gasoline, jet fuel, hydrogen sulfide, flue gas, industrial solvents
Methane, paint thinner, naphtha, propane, natural gas.Toluene, butanone
* cannot be used for measuring the concentration of COvalue for (non digital display)
Operations Guide
1 a clean environment to boot, the switch down "ON"position
2 of electricity enough green lights, blinking red LED lamp preheating, ticking sound the alarm will besounded, to eliminate the alarm sound, the turntable isfully counterclockwise.
3 to adjust the "tick" sound speed available thumbclockwise rotary dial until you hear a uniform "tick"sound. The red LED lights will flash
4 the probe near the suspected leakage area until the"tick" sound began to strengthen, the slight anti clockwise rotary dial to "tick" sound is abate, natural orcontinue to probe near the spill area, large sound again when the overshoot rate, until you find the leak location.
5 if the green LED lights flashing, said the need toreplace the battery.
6 if the environment is noisy, you can use the headset(plug headphones into the earphone socket).
7 if the instrument is not working or fault, please follow the manual work behind check parts for inspection.
Replace the battery
Check the work
The boot and the machine 1 minutes warm-up, gassource will probe exposure to known for example notignite the lighter gas (butane), close to the source ofnoise should be accelerated, away from the gas velocityshould be slow down, otherwise need to replace or repairthe probe further examination.
Note: this instrument shall be sent to the designatedrepair factory repair
Changing the probe
The 1 instrument shutdown
2 remove the probe cap
3 remove the old probe
4 replace the sensor and probe cap
5 re boot and "inspection".
