Hardwired Telemetry
DATAPAQ TP3
Resetting and Starting the Logger When Using Hardwired
Telemetry
The logger is reset and started exactly as for a normal (non-telemetry) profile
run (see p. 41), except that:
•
In the Reset dialog, select Hardwired Telemetry. (This option is not
available if Bluetooth communication is being used for the reset – thus,
ensure that logger and PC are connected by the communications lead.)
•
Multiple-run mode (p. 45) is not available with hardwired telemetry or
with Bluetooth telemetry (but is available with the TM21 radio-telemetry
system).
•
For use of multiple events with telemetry (different sample intervals and
trigger modes for different stages of the profile run), see p. 45.
•
After clicking OK in the Reset dialog:
○
If enabled, the Select Process dialog or the Select Oven, Recipe and
Product dialog then appears in order that you may choose a process,
oven, recipe or product file which will be applied to the results as the
profile appears on screen during the run. Click ‘No Process’ or ‘Cancel’ if
you do not want to apply one. (A process file allows you to see the
temperature profile in relation to the oven/furnace/kiln zones as the
profile appears on screen during the run. See p. 51.)
○
If enabled, the Apply Correction Factors dialog then appears in order
that you may choose a logger and/or thermocouple correction factor file
(see Insight’s Help system) to apply to the results. Click No Factor if
you do not want to apply a correction factor file.
•
Leave the communications lead attached to the logger and PC.
With the communications lead attached, the logger is powered via USB.
Batteries can be left in the logger, but they do not need to be fitted during
hardwired telemetry.
If using rechargeable NiMH batteries, it is possible to have the charger
connected during hardwired telemetry, but note that charging will stop as soon as
data-collection starts
(
see p. 22
.
In some circumstances, data collected maybe subject to errors from earth-loop
interference. If this is suspected, a suitable isolator should be fitted to the USB
connection; contact Fluke Process Instruments for advice
(
see p. 63
)
. Or use
Bluetooth telemetry
(
see p. 32
.
You may specify that a password is required when an attempt is made to close
Insight while a real-time telemetry run is in progress: select Tools >
Options > General.
