Validation & Calibration

G6110:
PAH calibration chamber and PAH chamber bushing tool are included in the
Calibration Kit.
Always place the PAH chamber bushing inside the chamber type that is in use. See
Figure 6-4.
G6111:
PAH calibration chamber is included in the Calibration Kit Refill.
G6110 & G6111:
It is possible to cross check sensor performance in measuring and calibration chamber
by using e.g., bottled water as test media.
Validation routines must follow the planned maintenance schedule found in section 8 in
this manual to ensure the correct performance of the PAH module.
Calibration of the PAH module is required when:
• The displayed validation value deviates more than ±5% of sensor range or
• The displayed validation value deviates more than ±5% of the nominal standard
test concentration, whose value is not less than 80% of the sensor range.
6.3.2 PAH Sensor Ranges
There are 3 different ranges available for PAH sensor:
• Low Range: 0-100 µg/l.
• High Range: 0-800 µg/l.
• Dual Range: 0-100/800 µg/l.
In dual range mode, the PAH sensor will automatically choose the range required.
6.3.3 Before Validation/Calibration
PAH SENSOR CHECK
1. Set VALVE 4 to VENT position.
2. Remove the locking plate and remove the PAH Sensor from its measuring chamber and
park it.
3. Check the optic(s) is/are clean. This is vital, so please use a cleaning pad free from oil.
