4�6�1 Removal of the Pump Adapter
To ease the removal of the Pump Adapter, follow the steps below.
1. Support the end of the Pump Adapter close to the inlet port using the
thumb of one hand.
2. Press on the top of the clip using the thumb of the other hand until a click
is heard.
3. Lift the Pump Adapter clear of the instrument.
4�7 Menus
While the gas monitoring screen is displayed, pressing the 3 button will provide
access to menus, depending on the model.
Calibration is not permitted until the sensors have warmed-up and been self tested or
if the pump is running. If you access the user menu under any of these circumstances
the Calibration option will not be available. The Safelink option (where applicable)
will not be available when the internal sample pump is running or when the batteries
are low (i.e. there is less than 1 bar on the battery indication meter).
4�7�1 Flammable Gas Selection
For catalytic sensors, it is possible to set the display to read for specific flammable
gases. Select the required flammable gas. The instrument will automatically adjust
its internal correction factors.
