4. Calibration and Setup
It is important to ensure that the initial set up of all types of sensor is
performed to ensure that they are wired correctly and pre calibration set ups
have been observed and are used in the manner described.
4.1. Zero Adjustment
Enter the sensor zero mode using the menu system. The zero is now set on
the display by using the UP and DOWN buttons. It is important to ensure
that the sensor being zeroed is not exposed to any gas whilst this is
happening, refer to sensor information to ascertain if any particular gas is
required to zero the instrument. Once zero is set press the SELECT button.
4.2. Span Adjustment
MUST ONLY BE DONE WITH CALIBRATION GAS and by qualified personnel.
Enter the sensor span mode using the menu system. Apply the gas to the
sensor in the manner prescribed by the sensor manufacturer and with the
correct gas. The level indicated on the display is then adjusted up or down
with the UP and DOWN buttons. The level is adjusted to read that indicated
on the span gas being physically applied to the sensor. The span/calibration
factor is then stored in the memory by pressing the SELECT button.
Do not adjust the span without gas on the sensor as this will effect the
calibration of the sensor on that channel.
