UEi Test Instruments CO91KIT - Manual (Page 4)

After the countdown is finished and the meter is correctly set up, take
the meter into the room to be tested, make sure its pump is on and use
the probe to draw in ambient air for the meter to measure.
• Only switch on the meter in OUTDOOR, FRESH AIR
• Do not exceed the meter’s internal temperature operating range
• Do not put the meter on a hot surface
• Do not expose yourself and others to dangerous levels of CO
Printing Test Information
An optional accessory for the CO91 is an infrared thermal printer. Read
the manual supplied with the printer prior to operation. Connection to
the Co91 is detailed below.
• Infrared thermal printer - this does not require a cable to transmit
the data but uses an infrared (IR) link similar to a TV remote
control. The IR emitter is positioned on the top of the CO91 and
the bottom of the printer. Ensure they are pointing at each other
and within 3 feet (1 meter), with not obstructions in the way. Data
may be lost if transmission is interrupted. Keep the CO91 pointing
at the printer until the printout has finished.
During combustion tests the CO91 will print data on request. With the
analyzer showing the “MAIN DISPLAY” press “ “ and current
data will be sent to the printer.
The display will show “PRINTING” until data transmission is complete.
After Using The Meter
After using the meter to test appliances, remove it’s probe from the flue
- IT WILL BE HOT - and let it cool. Do not put the probe in water which
will be sucked into the meter, damaging its pump and sensors.
When the meter readings return to ambient levels, switch off. The
meter counts down from 30 before switch off with the pump running
to self-clean its sensors.
Empty the water trap and check filter prior to storage and next use.
