8.4.5 Flow Calibration
The flow calibration menu is only available when the internal pump option is installed (refer to
Section 3.4.12).
The internal pump requires a separate flow calibration procedure. The flow calibration detailed in
Section 5.8 must be performed after any pump service or pressure calibration.
8.4.6 Internal Pump Leak Check
The internal pump requires a separate modified procedure to leak check the system (refer to
Section 6.4.4.1).
8.4.7 Pump Control
This section describes how to turn OFF and ON the internal pump for servicing and maintenance
purposes.
Procedure
1. Open - Main Menu → Service Menu → Diagnostics Menu → Internal Pump Menu.
2. Select - Pump Control → Manual.
3. Toggle OFF - Internal Pump → OFF.
8.5 Metric Fittings Kit (PN: E020122)
The metric fittings kit allows the user to connect 6 mm tubing to the rear ports of the analyser. This
can be very handy if it is hard to source 1/4” tubing from a local supplier.
8.6 High Pressure Zero/Span Valves
High pressure span calibration valve (factory installed (PN: E020108))
High pressure zero calibration valve (factory installed (PN: E020109))
For more information on how to setup and use the high pressure valves refer to Section 5.9.
Refer to Section 9.11 for the exploded assembly drawing.
Note: Before using a high pressure span or zero as a source for calibrating the instrument, check
local regulatory requirements.
