· Additional information.
Avoiding personal injury/damage to equipment
Do 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. Do 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. Do 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, DECT 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:
Deactivate Bluetooth function
Main menue - Settings - Buetooth - deactivate Bluetooth (Off)
Protecting the environment
Take faulty rechargeable batteries/spent batteries to the collection points provided for them.
Send the product back to Testo at the end of its useful life. We will ensure that it is disposed of in an environmentally friendly manner.
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 327-1 (O2, CO): Infrared interface
·testo 327-2 (O2, CO): Infrared / IRDA interface, memory, automatic sensor
diagnosis, option: Bluetooth (data interface)
Specifications
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 Data).

First steps
Charging rechargeable battery
Charge the rechargeable battery fully before using the measuring instrument.
The rechargeable battery can only be charged at an ambient temperature of 0...+35 °C. If the rechargeable battery pack has discharged completely, the charging time at room temperature is approx. 5-6 hrs.
Charging the rechargeable battery in the measuring instrument: The measuring instrument must be switched off.
1Connect the plug of the mains unit to the mains unit socket on the measuring instrument.
2Connect the mains plug of the mains unit to a mains socket.
-The charging process will start. The charge status will be shown on the display. The charging process will stop automatically when the rechargeable battery is fully charged.
Charging the rechargeable battery in charger 0554 1087 (accessory): Refer to the documentation that comes with the charger.

10 First steps
Operation with the mains unit
If the mains unit is connected, the measuring instrument is automatically powered from the mains unit. It is not possible to charge the rechargeable battery in the measuring instrument during operation.
1Connect the plug of the mains unit to the mains unit socket on the measuring instrument.
2Connect the mains plug of the mains unit to a mains socket.
-The measuring instrument is powered via the mains unit.
-If the instrument is switched off and a rechargeable battery is inserted, the charging process will start automatically. Switching the measuring instrument on has the effect of stopping rechargeable battery charging and the measuring instrument is then powered via the mains unit.
Switching on/off
Switching the instrument on:
Press .
-Initialisation phase:
·All display segments are lit (length of time: 3 s).
·Serial number, firmware version, instrument designation, date, time and countryspecific version of instrument are displayed (length of time: 5 s).
-The Measure flue gas option is displayed.
Switching the instrument off:
Press .
-sometimes: The pump starts and the measuring cells are rinsed until the
switch-off thresholds (O2 >20 %, other parameters 50 ppm) are reached. Rinsing lasts no more than 2 minutes.
Performing instrument settings
Performing settings:
1Press .
2Select Settings using / and confirm entry with the OK function key.
