Page 5: Introduction
INTRODUCTION The K1550 instrument is a MTL gas analyser that can be used for measuring the concentration of a variety of gases using a thermal conductivity sensor (commonly called a katharometer). A microprocessor is used to control the instrument and its associated digital circuitry to provide a highly advanced, highly featured, user-friendly gas analyser. -

Page 8: Installation
INSTALLATION Unpacking and visual checking Take all standard precautions when opening packages. In particular avoid the use of long bladed cutters. Search packing before discarding it to ensure that all of the components have been removed. Check that all pipe connections have captive seal nuts. Siting The instrument is designed to be panel mounting. - Page 9 KG 1550 Gas Analyser KG1550 MTL Gas analyser 2.5% H View Edit View Edit Meas Measure Calibrate Cal Gas Panel cutout 90 x 138 (+1/–0) OXYGEN CARBON DIOXIDE HITECH INSTRUMENTS Luton England.

Page 10: Sensor And Control/Display-Unit Connections
Sensor and control/display-unit connections CAUTION The sensor and control unit are matched during manufacture. Each instrument will operate correctly only with its own sensor. The sensor serial number is recorded on the test certificate supplied with the instrument. 3.6.1 Keyboard The connections for the sensor are located inside the sensor enclosure on the circuit-board backplane, adjacent to the cable entry gland. - Page 11 113.5 MTL Gas analyser remote sensor 120-0308-6 Figure 3a - Enclosure - nylon piping version Figure 3b - Enclosure - stainless steel piping version 163.5 Dimensions in mm MTL Gas analyser remote sensor 120-0308-6 Hitech Instruments Ltd. 260-0170 issue 1 Luton, England INM MTL 130-0031 Rev 14...

Page 13: Control/Display Unit Connections
The connections for the control/display unit are located on the rear of the case - with the exception of the K1550FX model which has the connections provided at DIN-rail mounted terminals. WARNING AC mains power (115 or 230V AC) is required to power the K1550 control/ display unit. -
Page 14: Operation
K1550FX model mounted in a hazardous area Connections to this display/control unit are provided on DIN-rail mounted terminals to the left of the display. Terminal identities are provided on a label below them - see Figure 8. M20 threaded holes are provided in the front wall of the flameproof enclosure for these connections - see Figure 2. -

Page 19: Calibration
CALIBRATION General The katharometer based analysers are extremely stable instruments and require only very occasional calibration. The exact calibration period depends on the type of sample and the environment in which the instrument is placed. In practice it is unlikely that check periods of less than one month will be necessary, and three to six months will be found to be more appropriate. -
Page 20: Calibration Method
Live zero instruments require an ‘upper’ calibration gas containing 100% of Measurand, and a ‘lower’ calibration gas concentration of >80% of span concentration of Measurand in carrier gas. The lower value of the instrument must be set prior to calibration but the ‘upper’ one is fixed at 100%. - Page 21 Calibration mode View View for upper cal. for lower cal.

Page 22: Compensation Calibration
Compensation calibration Instruments with compensation inputs have no calibration facility for the compensation signal. It is the user’s responsibility to ensure the accuracy of the compensation signal. To calibrate such instruments, apply a calibration gas that does not contain the compensated gas component. -
Page 23: Servicing
SERVICING The katharometer sensor is non-depleting and will last indefinitely if not subjected to misuse. If a replacement is required, it must be returned to your local MTL Gas sales office, because the sensor can only be replaced with the use of specialist equipment. NOTE When ordering spare parts or raising queries on an instrument, it is important that the serial number is quoted. - Page 24 MTL Instruments GmbH, Heinrich-Hertz-Str. 12, 50170 Kerpen, Germany UNITED ARAB EMIRATES Cooper Industries/Eaton Corporation Tel: +49 (0)22 73 98 12 - 0 Fax: +49 (0)22 73 98 12 - 2 00 Office 205/206, 2nd Floor SJ Towers, off.
