- TWA alarm is the lower value between TLV-TWA and allowable concentra on.

- When TLV-STEL is not speci!ed, it is set to three mes the TWA alarm value.

- This indicator measures the concentra on in the air of chemical substances, which became to gas, by

using a high sensi vity gas sensor.

How to Set “Gas Type (Gas No.)”

Select “Gas type (Gas No.)” at “Gas type se ng” in user mode.

1. User Mode and Switching Items

1) To start User Mode, press and hold [AVE. switch] and [ON/OFF switch] together while the power is

OFF un l the countdown of “USEr” !nishes.

be displayed with beep sounds.

2) Press [AVE. Switch] to switch items.

⇒ By pressing the switch, it switched sequen ally, in the order of "tyPE" (gas type se ng) to

"LGdL" (logging data erasing) to "AL" (alarm ON/OFF) to "bAL" (alarm test) to "diSP" (LCD

display test).

3) Select “tyPE” (gas type se ng) and press [ON/OFF switch].

⇒ See page 3 for se ng method.

2. End User Mode

The user mode ends by pressing [ON/OFF switch] un l "oFF" countdown !nishes while even under

se ng, and the power goes o".

Item Se ng Method

Gas type se ng Press [ON/OFF switch] when “tyPE” is displayed.

⇒ The ini al value “1” or the current status (from “1” to “17”) will blink.

To select gas number, press

[AVE switch] (in order: 1, 2) or

[AIR/Bz VOL switch] (backorder 2, 1)

Select gas number and press [ON/OFF switch] (s ll hasn’t been set),

“no” will !ash on the screen.

To save the se ng, press [AVE. switch] to blink “yES”, then press

[ON/OFF switch] to execute to override the se ng and it returns to the

“tyPE” display.

To not save the se ng, press [ON/OFF switch] while “no” is blinking, it

returns to “tyPE” display.
