Use DeLogger’s form window to view the
real-time data that the DT800 is returning to
your computer.
To do this…
a) Locate the minimized form window at the bottom of
DeLogger’s main window — it’s named
Form1.dlf
— and click its Restore button.
The form window is restored from its minimized
state.
b) Make sure that the form window is in Edit Mode.
Do this by checking for any of the following:
• the word “Edit” is present in the form window’s
title bar
• the formula bar is present at the top of the form
• the Edit Mode button is in the pressed position
If the window is not in Edit Mode, choose
Edit Mode
on the Form menu (or click the
Edit Mode
button).
c) Single-click in the
Channel
column of row 1.
The Select Channel for Row 1 dialog box opens. It
contains the name DeLogger has given to your
potentiometer channel.
d) Notice that the name is composed of
• the Connection name
•
A
— the “schedule ID” (this is the default
schedule ID; it is not replaced by any schedule
ID you create in the program builder)
•
1R
— the “channel ID”, which itself is composed
of the “channel number”
1
and the
R
esistance
channel type (this is the default channel ID; it is
replaced by any channel label you create in the
program builder — you’ll do this in “Add a
Channel Label” on page 55).
e) In the Select Channel for Row 1 dialog box,
highlight (one click) your channel name and click
OK
.
See also the “Clearing the Form Window” Extras
panel (page 42).
f) Turn Edit Mode
off
(un-tick
Edit Mode
on the form
menu, or click/release the
Edit Mode
button) and —
while watching the form window’s Value column —
turn the knob on the potentiometer.
Returned data (resistance) appears in the Value
column and is updated every half-second.
g) Turn the knob in both directions and observe the
effect in the trend indicator column (shows
U
p or
D
own) and the High Value and Low Value columns.
You may need to enlarge the form window or scroll
it horizontally to see these columns.
If turning the potentiometer knob fully anticlockwise
produces a maximum reading instead of a
minimum, reconnect the potentiometer using the
green and white wires instead of those used in
Figure 9 (page 15).
h) Experiment with the
Reset High
and
Reset Low
buttons to see the effect they have on the readings in
the High Value and Low Value columns.
