Key A: Tube Mode
Tube Mode is designed to accurately measure the level of benzene gas present using the
Benzene Pre-filter Tube. The initial benzene test has a test time which varies with temperature. This
test time is required to condition the tube, which then offers a proportional output relating to the
benzene being sampled.
Important
: A
must be carried out before Tube mode can be used.
The following icon will appear until a calibration is carried out:
.
The Tube Mode results will be automatically logged. They can later be reviewed in the Health &
Safety screen in Tiger PC (if available).
Important
: When entering Tube Mode, the pump will stop until the test cycle
begins. This is not a fault condition. The initial gas sample from the tube is used to
set the Zero, therefore it is essential that a clean tube is used.
Key B: Calibration
When selected, the user is presented with two options:
PID Calibration
•
Factory
: You can set your instrument to operate using the factory calibrated values.
These are set by ION Science Ltd or authorised service centres.
•
Custom
: You can carry out a Custom Calibration with the 10.0 eV MiniPID. Custom PID
calibration should be carried out as part of regular instrument maintenance.
•
Zero
:
This option is used to set the instrument either to the selected calibration Zero
(Absolute Mode), or to Zero against the ambient (Relative Mode):
Absolute Mode
uses fixed calibration Zero (either Factory or Custom
Calibration).
Relative Mode
sets the Zero level to the ambient.
Refer to
for details of calibration procedures.
