Installation

3.8.10 Instrument connections

The sensor is supplied with a cable having a LEMO connector at both ends. One end is
attached to the sensor and the other to the instrument.
A red dot can be seen on each LEMO connector and on both the sensor and instrument
sockets. Be sure to line up these red dots when connecting the cable to the sensor and
instrument. The LEMO connector can then simply be pushed into place.
Refer to the illustration of the connector panels for the correct instrument socket to attach the

Portable calibration device - K1200 sensor

The portable calibration device (part number 33088 illustrated above) is ideal for calibrating the
sensor close to its location in the sample.
The device is designed to hold a 1 liter gas cylinder (as shown above), but is fully compatible for
use with other kinds of gas cylinders. When using other types of gas cylinders, simply connect
the gas supply to the Swagelok connector (number 1 in
gas pressure does not exceed 2 bars absolute.
The gas bottle is not supplied and must be purchased locally. To ensure the calibration works
correctly, the calibration gas bottles must be of 99.999% (50) quality or better. Bottles containing
34 liters of compressed gas, with a 5/8-18 UNF (C10) fitting are compatible with the hand-held
calibration device and recommended for this purpose.
Empty gas bottles are easily removed from the device. Simply unscrew the small black screw
(number 2 in
the bottle from the pressure reducer. Follow this same procedure in reverse order to install a
new bottle.
