4. Disconnect the communications lead from the logger; the logger’s status
LEDs briefly flash red and green alternately to confirm logger reset – then
continue flashing alternately, at the chosen sample interval (maximum
5 seconds between flashes), to show that the logger is waiting to be
triggered. If trigger mode (p. 43) has been set to auto start, data-recording
starts immediately, and green LED flashes at sample interval (p. 16).
Using Previous Reset Options
From run to run, the logger retains the last-programmed set of reset options –
even if the battery has been removed in the meantime. Thus it is not necessary
to go through the reset procedure if the same reset options are to be re-used.
Instead, simply press the start button (and hold until LEDs flash) to start
data-collection with the same reset options as before (if trigger mode was set
to date and time, logging will nevertheless start immediately). Temperature data
which is still held in the logger and which has been downloaded will then be
overwritten.
The logger will not start logging if:
•
The logger contains data which has not been downloaded (thus, either download
the data, p. 48, or reset the logger with Insight and thereby delete the data, p. 41).
or
•
The logger’s internal temperature is above 45ºC/113ºF (see p. 33).
If using multiple-run mode
(
, you must reset the logger using Insight
before starting a new series of runs.
Starting the Run
See the dedicated
User Manual
for your Datapaq Tracker system, and/or consult
Fluke Process Instruments, for details of:
•
Choosing and installing appropriate thermocouple probes on your product.
•
Selecting an appropriate thermal barrier for the logger.
Ensure the thermal barrier has cooled sufficiently since its last use.
Before using a new barrier for the first time, or if you suspect a barrier has
absorbed moisture, you should run it once through your process without the logger
to remove the moisture.
Then, when the logger has been reset as above, proceed as follows.
1. Plug the thermocouples into the logger’s numbered sockets. If you are using
a process file (p. 51), ensure that the probe/socket numbers on the logger
correspond to those used to define probe numbers and locations in that file.
