3 Quick Start Guide - Normal Operation
Below is a general guide to get started but first ensure that the SDHmini
Portable Sample System (SDH-PSS) is located on a flat level and non-slip, safe
surface close to the sample point (gas source).
For faster results we recommend the sampling line to be as short as possible to
reduce the purging time. Please read this section carefully and understand it.
3.1 Installing the SDHmini into the Portable Sample System
Connect the SDHmini to the Portable Sample
System using the appropriate connecting tubes
supplied and ensure a gas tight seal on both sides
of the instrument (
Fig. 1
).
The user will need a 14 mm (⁹/₁₆”) open ended
spanner/wrench size and a 16 mm (⁵/₈”) holding
spanner/wrench to prevent rotation of the
bulkhead fittings.
Ensure the instrument Head is down fully (
Fig. 2
).
The instrument Head must be in the down,
closed position at this stage.
Ensure that (if
fitted) the pressure
regulator valve is
turned fully anti-
clockwise and is
fully closed (
Fig. 3
).
If a needle valve is fitted then ensure that this is
closed by turning fully clockwise (
Fig. 4
).
