battery is factory installed already . When switched off, the display
shows the battery capacity. The device has two buttons. (Fig. A). To
switch on, press one of the two buttons.
Note:
Both buttons switch the device on
The display briefly shows the firmware version and then the currently
measured temperature. The temperature sensor is located in the probe
tip. In order to measure the correct temperature, the sensor should
be at least 50 mm in the medium to be measured. To switch off, hold
down the ON button (1) for approx. 1.5 seconds. Switching on and off is
acknowledged by the device with a short melody. The display is a
paperwhite display and auto-aligns to the device orientation. This
ensures comfortable reading. The device switches off after 10 minutes
of inactivity.
5.1.4 Trend display
The measured temperature value is shown in connection with a trend
display (Fig: C, 9):
: temperature rises rapidly
: temperature rises slowly
: temperature remains constant
: temperature drops rapidly
: temperature drops slowly
5.1.5 Ambient conditions
(Fig: G)
The permitted device temperature is 32°F - 122°F. A separate temperature
sensor measures the device temperature directly behind the display. If
the device temperature exceeds the allowed range, a warning flashes
on the display. Return device to regular temperature immediately to
avoid damage.
5.2 Battery replacement / Battery status display
Replace batteries when the low battery indicator in the right corner of
the display (Fig: C, 6) appears .
