Gas Alarm Activation

When the gas concentration exceeds the alarm level, corresponding

gas concentration will blink, buzzer will sound intermittently, alarm

lamp will blink, AL1 and AL2 will appear on the LCD, backlight will

be on, and intermittent vibration will activate.

When the gas concentration falls below the alarm level, the gas

alarm will deactivate automatically (automatic reset).

3. Turn OFF the Power

Press the [ POWER] button to turn OFF the screen.

--> After a beep, “OFF” appears, the countdown starts 3, 2, 1, and then the LCD and the

power will be turned OFF with three beep sounds.

Gas Concentration Display

Up to four types of gas concentration will be displayed on the LCD at the same time. For

2-gas or 3-gas type model, only the target gas names and concentrations will be displayed.

(The following diagrams describe for 4-gas type models.)

•

When the gas concentration exceeds the service range

(see "

Specifications

" on page 37), "OL" will be blinking

on the concentration display.

•

If the detection failure is caused by sensor error, the

error message “E-S” will appear on the corresponding

sensor display. (See “

Error Messages

” on page 27)

<OFF>

See the chart on page 12 for the details on

concentration indicating “OL”.
