5. Operating Principle
The KOBOLD manual pressure measuring devices HND-P215 are highly precise,
compact pressure measuring devices that can be used universally. In conjunction
with the appropriate external pressure sensors, precise measurement results over
the entire measuring range can be achieved.
Various pressure sensors 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 pressure. All devices in this series allow for
minimum/maximum value memory, hold function, automatic self-shut-off, or zero
point offset entry for all connected pressure sensors, for example. The HND-P215
type also has a logger function, a peak value memory, or a minimum/maximum
alarm. A special characteristic of the type HND-P215 is the possibility of connecting
two external pressure sensors.
6. Electrical Connection
6.1 Mains Operation with Power Supply
Warning: When using a power supply please note that operating
voltage has to be 10.5 to 12 V
DC
. Do not apply overvoltage!! Cheap
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 power supply to the mains make sure
that the operating voltage stated at the power supply is identical to
the mains voltage.
