After initialization, the Posi est OTL will monitor all
thermocouple sensors connected to the ports. The green
Channel EDs will indicate the status of each port:
lLED Off: no thermocouple connected or open/damaged
thermocouple
lLED On: thermocouple is connected and status is good
4. Press and hold the Record button for 2 seconds to begin
recording datasets. One of the green Channel EDs will flash,
indicating the current batch number. The red ED beside the
Record button will remain lit indicating a recording is in
progress. A dataset is recorded every 2 seconds in one of 6
batches. The channel EDs will turn off after 5 minutes while
recording to preserve battery power. Tap the power or record
button to view.
5. Place the Posi est OTL in the Holder/Holder X within
the Barrier Box (see pg. 5) and ensure correct routing of the
sensor cables. Close the Barrier Box and secure the cover.
6. Attach the Barrier Box to a suitable hanger and send it
through the oven.
7. Remove the Posi est OTL from the Barrier Box as soon as
possible after the Posi est OTL exits the oven. Press and
hold the Record button for 2 seconds to stop recording
datasets. The red ED next to the Record button will turn off
when recording has stopped.

The Posi est OTL records up to 40,000 datasets into 6
independent batches (groups). A new batch is created each time
the Record Button is pressed for 2 seconds to begin recording
datasets. One of the 6 Channel EDs will flash, indicating the
current batch number. If all six batches are already populated,
stored measurements must be deleted to save new datasets.
The Barrier Box and Holder/Holder X will be HOT.
CAUTION:
8. Use the supplied USB cable to connect the Posi est OTL to
a Windows PC or Mac to download the datasets (see
“Accessing Stored Measurement Data”, pg. 4).
