Outline of the Product
Preface
Thank you for choosing our indoor carbon monoxide monitor EC-600 (hereinafter referred to as the
monitor). Please check that the model number of the product you purchased is included in the
specifications on this manual.
This manual describes how to use the monitor properly and its specifications. Not only the first-time users
but also the users who have already used the monitor must read and understand the operating manual and
use this product as described in this manual.
Note that the contents of this manual are subject to change without notice for product improvement. It is
also prohibited to copy or reproduce this manual, in whole or in part, without permission.
Regardless of warranty period, we shall not make any indemnification for accidents and damage caused by
using the monitor.
Make sure to read the warranty policy specified on the warranty.
Purpose of use
This carbon monoxide monitor measures carbon monoxide in the air and issues an alarm using the buzzer
and LCD backlight when carbon monoxide concentration rises over preset concentration (alarm setpoint).
While displaying measured carbon monoxide concentration on the LCD, the monitor converts it to an
analog signal of 4 - 20 mA or 0 - 1 V to output (only 0 - 1 V for the dry battery type) and outputs a two-step
gas alarm contact at a gas alarm state.
The monitor is a safety unit, not an analyzer which performs quantitative/qualitative analysis/measurement
for gas. Check the specifications before use and conduct measurement properly in accordance with
purposes.
