BARHOLE TESTING MODE
USER HANDBOOK
Stop purge when the live readings reach zero:
To stop purge:
• Press and hold OK .
The first barhole
screen is displayed
as shown in Fig. 6.5.
Up to six barhole readings can be stored. These are identied as
‘Barhole 1’ to ‘Barhole 6’.
After the rst reading is stored (as Barhole 1), the second reading
(Barhole 2) will be automatically selected, however, by using the
UP or DOWN buttons the user can specify where the next
reading will be stored. This may be useful if there was a problem
with the reading, e.g. sample fault.
The sequence of events will be as follows:
• Press and hold START to initiate timer and pump. Once
started, the user cannot stop a sample.
• Counter decrements from initial value.
• At ‘zero-time’, the
pump switches OFF
and the peak and
final sustained
(actual) readings are
displayed as shown in
Fig. 6.6.
