ION Science recommends that personnel responsible for equipment use
institute a regime of regular checks to ensure it performs within calibration
limits, and that a record be maintained which logs calibration check data.
Calibration
TIGER offers the following calibration options:
• Factory Calibration is set by ION Science Ltd during instrument manufacture or on re-
calibration by an ION Science authorised service centre, for example during an annual
service. Factory Calibration offers a safe set of three-point calibration data. This should be
used if the current custom calibration fails and will keep the unit working until a good
custom calibration is completed. Please contact ION Science Ltd or your local distributor for
further information.
ION Science Ltd recommends annual servicing and calibrations for users who require
traceable calibration records. During this service, the Lamp and MiniPID 2 Sensor are
brought back to factory specifications and new Factory Calibration data is loaded.
• Custom Calibration is performed by the instrument user and should be carried out as part of
regular instrument maintenance. Before doing so, first set up the calibration parameters in
TigerPC.
TIGER scales its linear output across a Zero level (clean air reference) and the SPAN 1 user-
defined gas concentration. Due to the linear output of the ION Science MiniPID 2 Sensor, a
two-point calibration is often adequate. However, for more exacting requirements, TIGER
therefore offers a three-point calibration which uses an additional SPAN 2 higher gas
concentration.
Custom Calibration
Before proceeding, ensure the calibration parameters are set in TigerPC:
TIGER allows you to custom calibrate using any gas from the Gas Table at any concentration from 10
ppm. You will need a cylinder of the gas at the chosen concentrations.
