Measuring Temperature with a HOBO Data Logger

Connecting

1. First you must open the HOBO by removing the top cover to gain access. Use an

Allen wrench to remove the four screws holding the top cover in place. Take care

not to lose the screws.

2. The dome nuts on the side may be removed with a 15mm wrench from the

channel you wish to access. For this experiment Channel 1 would be appropriate.

Then slide the black plug out. Do not throw the plug away, so that it may be used

to reseal the logger.

3. Slide dome nut over plug end of cable with threads facing in towards the case.

4. Feed plug end of thermocouple cable from the outside of the case through the

dome fitting of the desired channel. Plug it into the corresponding jack.

5. Thread dome nut back onto fitting. For this particular thermocouple the process

may be difficult.

6. There is a single dome plug on the center of one side. Use a screwdriver to

remove this and gain access to the communication port.

7. Plug the appropriate end of the serial cable into this port and the other end into the

computer.

Launching Data Logger

8. Activate the BoxCar Pro 4.3 software. There should be a short-cut icon for this

program on your desktop, if so, double-clicks to open it. If not you can access it

by going through “Programs” and finding it listed as “Onset Applications”. You

should come to a page similar to Fig. 1.

9. To launch a program to the logger click on Logger from the toolbar and choose

Launch. See Fig. 1.
