Pay particular attention to information emphasised by the following symbols:
· With the signal word Warning!:
Warns against hazards which could result in serious physical injury if
the precautionary measures indicated are not taken.
· With the signal word Caution!:
Warns against hazards which could result in minor physical injury or
damage to equipment if the precautionary measures indicated are
not taken.
· Additional information.
Avoiding personal injury/damage to equipment
o not make measurements with the measuring instrument and its sensors
on or near live components unless the instrument is expressly approved for
current/voltage measurements!
Never store the measuring instrument together with solvents and do not use
any desiccants.
Only operate the measuring instrument properly, for its intended purpose
and within the parameters specified in the technical data. o not use force.
Only carry out the maintenance and repair work that is described in the
documentation. Follow the prescribed steps exactly. Only use original spare
parts from Testo.
Any additional work must only be carried out by authorised personnel.
Testo will otherwise refuse to accept responsibility for the proper functioning
of the measuring instrument after repair and for the validity of certifications.
Temperatures given on probes/sensors relate only to the measuring range of
the sensors. o not expose handles and feed lines to any temperatures in
excess of 70 °C unless they are expressly permitted for higher temperatures.

Products with BluetoothÒ(Option)
Changes or modifications, which are not expressly approved by the responsible
official body, can lead to a withdrawal of operating permission.
Interference with data transfer can be caused by instruments which transmit on
the same ISM band, e.g. microwave ovens, ECT telephony, non-secure
software in cellphones when telephoning, transmitting/receiving text messages
etc.
The use of radio connections is not allowed in e.g. aeroplanes and hospitals.
For this reason, the following point must be checked before entering:
eactivate Bluetooth function

Specifications
Functions and use
The testo 327 is a hand-held measuring instrument for the professional flue gas
analysis of domestic and light commercial gas and oil boilers and appliances.
This includes condensing boilers and gas heaters. The unit is designed to carry
out tests shown in BS 7967, and has a timed tightness test, let by test and a
timed CO function.
These systems can be adjusted using the testo 327 and checked for
compliance with the applicable limit values.
The testo 327 is available in four versions; the scope of function varies
according to the version:
· testo 327 O2: Infrared interface
· testo 327 CO: Infrared interface
· testo 327-1 (O2, CO): Infrared interface
· testo 327-2 (O2, CO): Infrared / IR A interface, memory, automatic
sensor diagnosis, option: Bluetooth (data
interface)
Warning The testo 327 must not be used in areas at risk of explosion,
for long-term measurements or as a safety (alarm) device!
The testo 327 with the Bluetooth option may only be operated in countries in
which it is type approved (see Technical ata).

Connecting probes/sensors
The instrument needs to detect which probes or sensors are connected, before
switch on. If you fail to do this simply turn off instrument connect probe and
re-start unit.
CCoonnnneeccttiinngg tthhee pprroobbeess::
Insert the connector into the flue gas

There must be no more than one extension

instrument and the flue gas probe.
CCoonnnneeccttiinngg tthhee sseennssoorr::
If no ambient air temperature sensor is connected, the temperature
measured by the thermocouple of the flue gas probe during the zeroing
phase is used as the ambient air temperature. All dependent parameters
are calculated using this value. This method of measuring ambient air
temperature is sufficient for systems dependent on ambient air. However,
ensure that the flue gas probe is near the intake duct of the burner during
the zeroing phase.
If an ambient air temperature sensor is connected, the ambient air
temperature is measured continuously by this sensor.

AAmmbbCCOO: current ambient CO value in ppm.
aavveerr..:average ambient CO value in ppm. Every minute the average
value is calculated. If the measured value is lower than the min value,
the min value will be set to the current value. If the measured value is
higher than the max value, the max value will be set to the current
value.

- Alarmlevels:
Current value > 10 ppm: The value blinks (1 sec on / 1 sec off).
Current value > 30 ppm: The value blinks (0.5 sec on / 0.5 sec off).
- After measuring time the average ambient CO value is displayed.

Condensate trap
The fill level of the condensate trap can be read from the markings on the
condensate trap.
EEmmppttyyiinngg tthhee ccoonnddeennssaattee ttrraapp
Flue Gas condensate consists of a weak mix of acids. Avoid contact with the
skin. Make sure that the condensate does not run over the housing.
Caution! Failure to empty the condensate trap when the fill level is
reached results in condensate entering the sensors and pump. This
voids the warranty and results in costly repairs and replacements.
o not empty the condensate trap while the flue gas pump is in
operation!
11Keep measuring instrument in an upright
position (condensate outlet pointing upwards).
22Open the condensate outlet on the
condensate trap: pull out approx. 7 mm to
the stop.
33Let the condensate run out into a sink.
44Mop up any remaining drops on the
condensate outlet using a cloth.
55Close the condensate outlet.
The condensate outlet must be completely
closed, otherwise measuring errors could occur if external air gets in. It is
advisable to empty water trap at regular intervals, (preferably daily).
