5. Operating
Principle
The KOBOLD manual pressure measuring devices HND-P105 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.
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.
6.1.1 Connecting/Changing
Sensors
Do not use unsuitable sensors. Connecting other devices/sensors as specificated
may cause a damage to the instrument and device/sensor! Switch off device
before changing the sensor.
Connect sensor before switching on the device, otherwise the sensor may not be
detected correctly. When connecting the sensor the connector may not lock
correctly. In such case take the plug not at the casing but at the buckling
protection at the end of the plug. If plug is entered correctly, it will slide in
smoothly. To disconnect sensor do not pull at the cable but at the plug (to open
locking mechanism).
