General Tools and Instruments HT50 v.1 - Manual (Page 14)

OPERATING INSTRUCTIONS
DEPLOY THE UNIT
The HT50 is particularly easy to deploy on a job site because
the unit does not need to be plugged into a computer to be
activated (ready to start logging data). Working together, the
SET and STO buttons and the LCD serve as the control and
indicators needed to: 1) start and stop data logging and
2) verify and change the unit’s working status.
That leaves only two things to be sure of when choosing a
place to deploy the HT50:
• The temperature and humidity sensor window
(Fig. 1a, Callout I) is not covered
• The humidity and temperature values at the unit’s
location are “representative” of the room
The HT50—with its protective cap on—can be deployed
either by laying it on a horizontal surface or by hanging it
vertically within the included plastic mounting bracket.
The back of the bracket features both a magnet and a
hanger hole.
Once you have deployed the HT50, you can initiate data
logging. To start logging ambient temperature and
humidity data (but not IRT measurements), press and hold
the SET button for at least 3 seconds. The LCD will display
the word “LOG” to confirm that logging has begun. To
start logging ambient temperature and humidity data as
well as IRT measurements, press the hold the STO button
for at least 3 seconds. The LCD will display the words
“LOG” and “IRT’ to confirm that logging has begun.
