Notes on the operating instructions

-  The operating instructions are in-

tended for specialist workers and 

trained personnel. 

-  Before each stage of work, read the 

relevant notes and warnings care-

fully, and keep to the sequence as 

stated. 

-  Pay particular attention to the sec-

tion 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
The high pressure calibrator enables 

pressure to be generated by means of 

the integrated pressure pump, up to 

700 bar relative.

The measurement technology incor-

porated into this device allows ac-

curate measurement and documen-

tation 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 ob-

jects (transmitters or pressure switch-

es) must be supplied from an external 

source.

Pressure range for the display
High pressure calibrators are them-

selves calibrated with the ambient air 

pressure as the zero point reference. 

The Zero function allows any desired 

pressure value to be set as the new 

zero point reference. 

To take relative measurements, 

the high pressure calibrator is 

 

zeroed at ambient pressure (

Set 

Zero

). To reset the pressure zero 

point to the factory setting, use the  

RES Zero 

function (reset zero).

Commissioning
A pressure-resistant connection for 

the test object is required in order to 

use the high pressure calibrator. The 

pressure connection for the test object 

is already screwed to the pressure  

distributor of the high pressure calibra-

tor 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: 30 Nm

IMPORTANT!

Nothing must adhere to the surface of 

the test object (no oil, grease, water, 

etc). Impurities could pass through the 

adapter to reach the high pressure 

calibrator and damage it.

Overpressure
If the pressure exceeds the measuring 

range by more than 20%, the measur-

ing cell or the mechanism of the high 

pressure calibrator may be destroyed.

Recalibration 
The recalibration cycle depends on 

the conditions of use. Recommended 

recalibration cycle: 1 year.

Intended use
The high pressure calibrator (HPX) 

may only be used to generate pres-

sure with the type HLP 22 BP hydrau-

lic oil that is supplied with the product. 

Use of the calibrator with other media 

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: ”Tech-

nical data”) must never be exceeded. 

Before installing the high pressure 

calibrator, check that it is suitable for 

your applications.
