Page 13: Sampling The Flue Gas
Sampling the Flue Gas Once the automatic calibration procedure has been completed and the specific fuel has been selected (See SELECT menu) the probe can be inserted into the desired sampling point. It is recommended that the sampling point be located at least two flue diameters downstream of any bend and that the probe tip is in the centre of the flue. -
Page 14: Regular Checks During Sampling
Regular Checks During Sampling Care must be taken at all times not to exceed the analysers operating specifications, in particular ensure the following :- • Do not exceed the maximum temperature of the flue probe. • The analyser internal temperature does not exceed normal operating range, typically 0- 40°C. -
Page 15: Electromagnetic Compatibility
Electromagnetic Compatibility The European Council Directive 89/336/EEC requires that electronic equipment does not generate electromagnetic disturbances that exceed defined levels and has an adequate level of immunity to enable it to be operated as intended. The specific standards applicable to this product are detailed in the appendices. -

Page 23: Printing Information
PRINTING INFORMATION Supplied as accessories for the KANE940 are an infra-red thermal printer or a dot matrix serial printer. Read the manual supplied with each printer prior to operation. Connections to the KANE940 are detailed below : • Infra-red thermal printer - this does not require a cable to transmit the data but uses an infra-red (IR) link similar to a TV remote control. -
Page 24: Storing And Retrieving Data
STORING AND RETRIEVING DATA The KANE940 can store up to 100 combustion tests. Once stored, the data can be viewed on the display or downloaded to a PC or printer. Storing a ‘Live’ Test While performing a test and viewing the data on the MAIN display access the STORE menu as follows :- Press STORE MENU... -
