5-3. Change of the measuring mode (only for fumigation

gases)

The measuring mode of the detector (for fumigation gases) can be switched from "concentration measuring
mode" to "differential measuring mode", where lower concentration detection can be conducted.

1

On the "MODE CHG"
screen in the display mode,
press the POWER button.

The detector enters the setting
to switch the measuring mode.

2

Press the MODE or AIR
button to select the
measuring mode.

The measuring mode switches
to the other every time the
button is pressed.

<Concentration measuring

mode>

<Differential

measuring mode>

3

In the appropriate
measuring mode, press the

POWER button.

"END" is displayed, returning to
the display mode.
