MOUNTING AND STARTUP
1. Select location for display. A location that is out of direct sun-
light provides best visibility.
Note: The Temp Tracker may be mounted from a bulkhead
or installed in a flush panel by removing the mounting
bracket. Panel cutout dimensions are given in the specifi-
cations. An optional rack mounting panel is available from
your YOUNG supplier.
2. Connect cables to terminals. Refer to wiring diagram.
3. Connect GND terminal to suitable earth ground.
4. Insert power supply plug into power jack, plug AC adapter into
wall outlet.
5. The Temp Tracker will display a software version number for
several seconds. It will then begin to display temperature &
humidity information. The following information is displayed:
• Temperature
• Relative Humidity % (or Dew Point °)
• Alarm status
6. Observe the display for a few minutes to verify that it is operat-
ing properly. To change settings see the following section.
CHANGING SETTINGS
The Temp Tracker has a setup mode that allows you to easily
change input type, temperature units, alarm settings, and other

ADDITIONAL INFORMATION
ALARMS
Alarm functions for temperature, humidity (or Dew Point) are ac-
cessed in the SETUP sequence. Either or both alarms may be
selected. Each alarm has a LO and a HI setpoint. When the indi-
cated value goes below the LO or above the HI setpoint, the alarm
indicator blinks, and the associated relay contact closes. When a
delay time is set, the indicator reports an alarm condition only after
it has existed for one complete delay period. Alarm activity ceases
when conditions are outside the alarm range for one complete
delay period. For a "latching" alarm effect, use the Temp Tracker
relay contacts to activate an external latching-type relay.
BRIGHTNESS
Adjust display brightness by holding the BRIGHT key.
DEW POINT
Dew Point is displayed in the right display window by selecting this
feature during SETUP. Dew Point values are calculated from tem-
perature and relative humidity measurements. Dew Point is shown
in the same units as those selected for temperature ( °C, °F ). The
"DEW POINT" label included may be placed over "RELATIVE
HUMIDITY %" on the front panel.
