Press the key again for a combination of the audible and visual alarm. Pressing the key a third time will return the unit to its initial audible only tting.
2. 警报设置键:当打开此组件时,能听到警报响声。第一次按警报设置键时,能打开视觉警报(可视警报)功能;再按一次警报设置键时,可同时打开听觉、视觉警报功能;第三次按警报设置键时,只有听觉报警功能开启。
3.SENSITIVITY Key: The LS790B offers 10 ranges of nsitivity that may be lected depending on the type of refrigerant you're working with and the size of the leak. The lowest nsitivity range is automatically lected each time the instrument is switched on. Depress and hold the SENSITIVITY key to change the nsitivity range. The LED will move left to right (LO to HI) until the key is relead.
3.敏感测试键:LS790B测漏仪提供10个敏感等级。这十个等级是由您使用的冷却剂种类和泄露面积所决定的。其中,最低敏感等级是在此仪器打开之后自动启动的。您可以通过长按敏感测试键的方式来改变它的敏感度范围。仪器上的LED灯将会在您长按按键的同时从左到右移动,改变敏感度等级,直到您停止长按按键。

This mode of operation measures and records in memory the highest concentration of refrigerant gas detected since the mode was lected or the RESET button was depresd. Any concentration of gas less than highest recorded concentration is locked-out or ignored, thereby eliminating the effects of background contamination. A distinct two-tone alarm will sound when the probe is in the area of the highest refrigerant concentration. This will be the leak source.
4.锁定键:在高度污染的环境中搜寻泄漏源时,您可以使用这一功能。这一操作模式的启动可以通过按LOCK OUT键(锁定键)或RESET键(重新设定键)的方式启动。此操作模式旨在测量并记录能够测量到的最高浓度的冷却剂气体的位置。任何低于最高浓度的冷却

剂气体或者被锁定,或者被自动忽略。通过此方式来排除背景污染物的影响。当探测器处于冷却剂浓度最高的地方时,您将会听到探测器发出响亮的两声为一组的报警。此时探测器的位置就是泄漏源。
