Dwyer Instruments 1205A-5 Installation And Operating Instructions

Model 1205A-5 Handheld CO Analyzer provides a simple, cost effective
answer to detecting and monitoring colorless, odorless, toxic carbon monox-
ide. The portable, battery operated unit measures CO from 0 to 2000 ppm
and can record maximum CO values. Use a Type K thermocouple (sold
separately) to measure temperatures. Simultaneously display two differ-
ent functions on the large two-line alpha-numeric LCD. Quickly program
time, date, engineering units, language and other display functions. The
rotary dial allows easy function selections. The analyzer features auto
zeroing, battery indication, infrared printer link, and a backlight display for
low light areas. The Model 1205A-5 is ideal for ambient air monitoring in
residential and commercial markets, flue testing in small boilers, and source
investigation in areas where CO monitors have alarmed. The unit includes
a stainless steel flue probe with filter and flexible tubing, batteries and
instruction manual.
INTRODUCTION
The 1205A-5 meter tests CO levels in heating appliances, ambient air,
around fossil fuel appliances like cookers and grills. It also helps you test
residential and commercial CO alarms and also shows CO MAX - the max-
imum level of CO recorded.
The 1205A-5 can also be used as a digital thermometer, ideal for testing
hot water or refrigeration.
A large backlit display shows 2 readings, and all data can be printed via
an optional printer. The printout shows complete data and includes the
date and time.
The 1205A-5's protective rubber boot has a magnet for "hands-free" oper-
ation when using probe to test combustion appliances and ambient air.
The 1205A-5 is controlled using 4 buttons and a rotary dial.
The four buttons (from left to right):
1. Power Switch to turn the meter on and off.
2. Print actual or frozen data and switch on and off the backlight.
3. Switch on and off the pump.
4. "Freeze" or hold data.
The buttons with UP, DOWN and ENTER arrows also change settings
such as date, time and the display's top line.
The rotary dial changes the display's second line and also accesses the
menu to allow changing the date, time, etc.
