4. NAMES AND FUNCTIONS OF PARTS
1. Measurement switch (trigger).
Pull trigger to display temperature value, and “SCAN” appears on screen at
the same time; when trigger is released, temperature reading is displayed,
and data is automatically maintained. The instrument automatically shut
down after about 30 seconds of operation.
2. Laser switch/Down button.
3. MODE (mode switch button) / temperature unit switch button
Press MODE button to cycle through four modes, MODE 1—MODE 2—MODE
3—MODE 4.
• Mode 1: Mildew alarm mode. Under this mode, the current ambient
temperature, humidity, dew point temperature and surface temperature
are displayed. Pull trigger to measure surface temperature.
•
Note: The instrument decides whether the measured object is easy
to mildew according to the surface temperature of the measured
object and the dew point temperature of the current environment.
Indicator light turns green for normal state. If the measured object
tend to mildew, the indicator light turns yellow; if already mildew,
the indicator light turns red.
• Mode 2: Temperature difference alarm mode. Unde this mode, pull
trigger to display the current ambient temperature and the surface
temperature of the measured object. When the surface temperature of
the measured object is close to ambient temperature, the indicator light
turns green; if much higher than or lower than ambient temperature,
the indicator light turns red. Otherwise, the indicator light turns yellow.
