5.4.5 SAMPLE INITIATION using External Contact
The following sequence of entries are made
on the Touchpad to form a basic operating
parameter for operation of the sampler. This
will determine the time between samples
being taken. The ACTIVE SETTINGS are
not being altered.
1. Press the SET key.
2. Press the SAMPLE INITIATION key.
3. Press an ARROW key. Continue until
External Contact is shown on the display.
4. Press the ENTER key.
The display will echo the last entry with
<ENTERED>.
The controller has now been given a new
value for SAMPLE INITIATION. The new
value resides in the NEW ENTRIES area of
the controller memory. To make this change
active, press the RESTART key, then again
press it to confirm your choice. The
controller will then wait until a contact
closure has been received before taking a
sample.
Summary of Sequence:
