C35-FC
6. First Power Up and Commissioning
Once Once C35 has powered on, a boot-up screen will be displayed. The home screen, as shown
on page 12 , will appear once the device has fi nished booting up.
NOTE: The internal sensors require time to stabilise and power up. Only adjust offsets
once the unit has had suffi cient time (outlined below) to complete this process.
6.1. Temperature measurement
The C35 uses an Internal Temperature Compensation (ITC) algorithm to eliminate heat
generated by internal electronic components.
NOTE: The ITC Algorithm requires up to 30 minutes to stabilise and achieve accurate
temperature readings. Thermal resistance of the surface on which the device is
mounted will affect temperature readings.
Once the required time has elapsed, compare sensor readings against a reference instrument. If
required, the device can be calibrated using the Offsets menu instructions on page 26 .
6.2. Relative humidity measurement
The built-in humidity sensor (optional) utilises temperature readings to calculate relative
humidity. Allow 30 minutes for the device to calculate accurate readings of temperature and
relative humidity, prior to adjusting offsets.
NOTE: If offset is added to temperature readings, it will affect relative humidity readings.
7. Touch screen operation and Maintenance
The C35 - is primarily operated through its 3.5” resistive touch screen.
•
The screen should not be operated with sharp objects which can scratch or damage the
screen
•
To clean the screen, simply wipe the front- facing screen using a slightly damp cloth
CAUTION: Do not expose the device’s vents to liquids and do not use any cleaning agents on
the device as this may result in sensor malfunction or incorrect readings.

4. To remove or detach device from the wall mount, press the release bracket on the
bottom of the device and then pull the device upwards.
Warning : Ensure that the power supply has been switched prior to removing the device from
the wall mount.
