Fig. 6.5 Barhole Timer

Up to six barhole readings can be stored. These are

identified as Barhole 1 to Barhole 6.

After the first 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 sam-

ple.

 Counter decrements from initial value.

 At zero-time, the pump switches OFF and the

peak and final sustained (actual) readings are dis-

played as shown in Fig. 6.6.
