Notes on the operating instructions
- The operating instructions are intended for specialist workers and
trained personnel.
- Before each stage of work, read the
relevant notes and warnings carefully, and keep to the sequence as
stated.
- Pay particular attention to the section on ”General safety warnings”.
If you have any problems or questions,
please contact your supplier or
consult KELLER directly.
1. Description of the device
General description
By means of the pressure pumps
supplied with the product, the lowpressure calibrator enables the generation of pressures of -0,85 bar
relative (with the vacuum pump) to
+10 bar relative (with the hand pump).
The measurement technology incorporated into this device allows accurate measurement and documentation of the characteristic of a test
object that is connected to it. The
measured pressure progression can
be displayed, evaluated and saved
with a computer monitoring program
(CCS30).
The calibrator is operated with
the two function buttons SELECT
and ENTER, located directly
below the display. The calibrator itself is powered by a 3,0 V battery, but
power can also be supplied externally
via the K-114A interface converter.
Test objects (transmitters or pressure
switches) must be supplied from an
external source.
Pressure range for the display
The low pressure calibrator has a
factory-set pressure zero point of
0 bar absolute (vacuum). The Zero
function allows any desired pressure
value to be set as the new zero point
reference.
To take relative measurements,
the low pressure calibrator is
zeroed at ambient pressure (
Zero
). To reset the pressure zero
point to absolute pressure, use the
Set
RES Zero function (reset zero).
Commissioning
A pressure-resistant connection for
the test object is required in order to
use the low pressure calibrator. The
pressure connection for the test object
is already screwed to the pressure distributor of the low pressure calibrator
so that it is pressure resistant when it
leaves the factory, and it must not be
dismantled.
Recommended torque for the test object pressure connection: 10 Nm
IMPORTANT!
Nothing must adhere to the surface of
the test object (no oil, grease, water,
Impurities could pass through the
etc).
adapter to reach the low pressure calibrator and damage it.
Overpressure
If the pressure exceeds the measuring
range by more than 20%, the measuring cell or the mechanism of the low
pressure calibrator may be destroyed.
Recalibration
The recalibration cycle depends on
the conditions of use. Recommended
recalibration cycle: 1 year.

Intended use
The low pressure calibrator (LPX) may
only be used to generate positive or
negative pressure with air. Use of the
calibrator with other media, especially
hydraulic oil, will damage it. The operational safety of the device supplied
is guaranteed only if it is used as intended. The limit values as stated (see
page 19: ”Technical data”) must never
be exceeded.
Before installing the low pressure calibrator, check that it is suitable for your
applications.

2. General safety warnings
The current national regulations on
accident prevention and workplace
safety must be followed whenever
work is carried out. Internal regulations issued by the operator must be
followed, even if they are not mentioned in these instructions.
Never use the low pressure calibrator together with an external pressure
source.
Do not remove any connected components (e.g. test objects) when the low
pressure calibrator is under pressure.
Open the pressure relief valve before
removing one of the parts.
Only use the adapters and seals that
are available as accessories.
Do not store the calibrator under pressure: only store the low pressure calibrator with the pressure relief valve
open.
Avoid the action of force of any kind
on the low pressure calibrator and its
operating controls.
Do not use low pressure calibrators if
they are damaged or faulty.

3. Operating the LPX calibrator
Operating the pressure calibrator is described starting on page 16.
Connect the test object
You can connect your test object to the
low pressure calibrator via the pressure
connection (9).
Zeroing the device
Engage the hand pump (5) in the connection port (10). Open the pressure
relief valve (until the red mark is visible
at most) to release any pressure that
may be present. If the pressure display
does not show zero, perform a zeroing
procedure
(Set Zero)
. Then close the
pressure relief valve.
Pressure generation
You can use the hand pump (5) to make
an approximate setting for the desired
pressure.

The SELECT button positioned on the
front is used to switch the device on,
to select a function and to select the
various pressure units.

Battery
The pressure calibrator is powered by a
3 V button-cell battery (behind the
display). If the battery is low, the battery symbol on the display
lights up.
Replacing the battery
Please switch the device off. Turn the
display section ring beyond the limit
stop until it is released from the housing section (turn through about 180°).
Open the battery compartment and
change the battery (type CR 2430).
