2  TECHNICAL CHARACTERISTICS

CO Display Range ............... 0-1999 ppm CO
Accuracy .............................. ±10 ppm or ±5% of reading 
 

whichever is greater*

Response Time ..................... 90% of fi nal value within 40 sec.
Battery Requirements ........... 1.5 V, “C” cells, Qty. 4
Operating Time** ................ 14 to 16 hours, alkaline cells
Operating Temp. Range ....... 23 to 104°F (–5 to 40°C)
Relative Humidity ................ 10 to 85% non-condensing
Weight (w/o batteries) .......... 12 ozs. (341 grams)
Dimensions .......................... 8.6 x 3.5 x 2.9 in. (218 x 89 x 74 mm)

To prepare the instrument for operation, you 
must install four “C” size batteries, and (if 
desired) install the hose and probe as described 
in the following paragraphs.

For your convenience, and to ensure that the 
instrument will provide reliable CO indications, 
the CO sensor is installed and the instrument 
calibrated on 500 ppm of CO at the factory.

3.1  Battery Installation

Detach the elastic strap's metal clip at the bottom 
of the instrument, and slide off the battery cover 
as shown in Figure 2. Then while observing 
proper battery polarity, install four “C” size 
batteries into the instrument’s battery compart-
ment. (Recommended battery types: Duracell 
Alkaline or equivalent). After the batteries 
are installed, replace the battery cover and the 
elastic-strap clip.

*  Tighter accuracy in the lower ranges, up to ±2 ppm, may be attained if 

lower range calibration gases (eg. 100 ppm) are utilized.

** Times are with the backlight turned off. Continuous use of the backlight 

will decrease battery life.
