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.
