5. Operating Principle
The KOBOLD hand-held temperature measuring units HND-T205 are highly
precise, compact thermometers for PT100 4-wire-probes that can be used
universally. The high degree of accuracy of these housings makes them
extremely well suited for all calibration tasks. In conjunction with the appropriate
temperature probes, precise measurement results over the entire measuring
range can be achieved. Various probes are available for a multitude of measuring
tasks and special applications. The respective measurement task determines
which combination is selected. Naturally, these first-rate KOBOLD-measuring
units can display more than just the temperature values. All housings in this
series allow for minimum/maximum value memory, hold function, automatic self-
shut-off, and zero point/increase entry, for example.
6. Electrical Connection
6.1 Mains Operation
Attention: When using a power supply unit please note that
operating voltage has to be 10.5 to 12 V
DC
. Do not apply
overvoltage!! Simple 12 V-power supplies often have excessive
no-load voltage. We, therefore, recommend using regulated
voltage power supplies. Trouble-free operation is guaranteed by
our power supply HND-Z002.
Prior to connecting the plug power supply with the mains supply
make sure that the operating voltage stated at the power supply
is identical to the mains voltage.
Treat device and probes carefully. Use only in accordance with above
specification. (do not throw, hit against etc.). Protect plugs and sockets from
soiling.
To disconnect sensor plug do not pull at the cable but at the plug. When
connecting the probe, the plug will slide in smoothly if plug is entered correctly.
Selection of Output-Mode
: The output can be used as serial interface or as
analogue output. This choice has to be done in the configuration menu.
