Statistical characteristics – minimum, average, maximum of all measured
and calculated values in the respective measurement units
Date and time – output to measurement records.
1.3 Logger mode
Scope – 4680 measurements each with measured pressure and humidity
values and two measured temperature values (when external sensor atta-
ched), i.e. max 18,720 measured values
These measured values can be stored in memory for over ten years, even
without batteries.
IrDA data transfer, also while data are being registered
User-selectable scan intervals – 30 s, 1 min, 3 min, 10 min, 30 min, 1 h, 3 h,
4 h
Control on undervoltage

Storage temperature – -20 °C to +60 °C
Operating temperature – -5 °C to +60 °C in logger mode (excl. display); incl.
display 0–50 °C
Mass – approx. 450 g with protective bag and magnet excl. hose

2. Controls and connections
Figure 1 below shows the indicators and controls on the DC 2000
PRO
. The
display always shows the trend ▼▲on the left, the numerical value in the
middle, and the corresponding unit of measurement on the right. When a key
is pressed, a cursor ▲ appears in addition at the edge of the display to mark
the subprogram near the display label. This menu is activated when the
cursor flashes.
The functions assigned to the keys resemble those on a mobile phone. In
general, the ± key on the left increments or decrements an entered value or
displaces to the left or right the cursor ▲ (1) at the edge of the display (see
Figure). A short double tap on the ± key switches from increment to decre-
ment mode or reverses the cursor’s movements. This toggle function is indi-
cated by a dot at the centre of the display (2). A second double tap switches
back to increment mode or restores the cursor’s original direction.
Example: Pressing the ± key moves the cursor from its position 1 (“Pre-
