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 TigerPC (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 10.0eV 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.
Using Advanced Mode
Key A: Tube Mode
Once TACs have been detected, Tube Mode is designed to identify the level of benzene gas
Key B
In Advanced Mode, the
B
key can be configured to select multiple functions which can be accessed
by using the
