2.0 Safety instructions

Read this manual carefully before using

the system!

Please follow the instructions and procedures described in

this manual. They are designed so that you get the most

out of your pressure system and avoid any personal

injuries and/or damage to the system.

Warning……

About the handling:

• Avoid knocking, bumping or dropping the pressure

system. This can cause permanent damage to the

system and loss of accuracy.

About the use:

• The pressure system must not be used for any

purposes other than those described in this manual and

for any application other than precision pressure

calibration jobs.

• The pressure system should only be used by TRAINED

PERSONNEL.

• Never subject the pressure gauges to overpressure. In

case of overpressure the gauge should not be used for

calibration purposes.

• None of our calibration systems are cleaned or

prepared for OXYGEN MEDIUMS so DO NOT USE our

systems for this purpose.

• Do not disconnect any parts from the system when

pressurised.

• Do not connect any external pressure source to this

system. This system is designed to test pressure

measuring devices connected to the manifold only.

Pressure from an external source can result in

explosion of the liquid reservoir and possible personal

injuries.

3.0 Identifying your JOFRA Pressure

Calibration System

3.1 Model description

The T-620/T-620H hydraulic pressure hand pumps are specially

designed for high pressure applications. The pumps are compatible

with petroleum-based oils or hydraulic fluids.

The T-620 pump generates up to 200 bar (3,000 psi) and the T-620H

pump generates up to 350 bar (5,000 psi).

All pumps feature a 0.5 pint/200 cl built-in oil reservoir, vent valve and

vernier valve for fine adjustment. The pumps have dual pressure

output – one for the test object and one for the indicator. Easy

connection between pump and indicator.

The System C can be used with one of the following instruments :

DPC-500, APC, IPI, APM-S/H or together with either a T-620 or a T-

620H hydraulic pressure hand pump depending on the chosen

pressure range.

3.2 Receipt of the JOFRA Pressure Calibration

System C

The Pressure Calibration System C is delivered complete assembled

as standard in a carrying case and should always be placed in the

carrying case after use.

4.0 Operating instructions

Warning……

About the handling:

• Avoid knocking, bumping or dropping the pressure

system. This can cause permanent damage to the

system and loss of accuracy.

About the use:

• Do not attach the pump to a high pressure source.

Please notice that the pump comes in 2 different

pressure ranges. Therefore it is very important to check

the version of the pump to avoid over pressure of

indicator.

Follow these instructions carefully to avoid damage to

the system and/or personal injuries.

• The pressure system must not be used for any

purposes other than those described in this manual and

for any application other than precision pressure

calibration jobs.

• Never subject the pressure gauges to overpressure. In

case of overpressure the gauge should not be used for

calibration purposes.

• The pressure system should only be used by TRAINED

PERSONNEL.

• None of our calibration systems are cleaned or

prepared for OXYGEN MEDIUMS so DO NOT USE our

systems for this purpose.

• Do not disconnect any parts from the system when

pressurised.

• Do not connect any external pressure source to this

instrument. This unit is designed to test pressure

measuring devices connected to the manifold only.

Pressure from an external source can result in

explosion of the liquid reservoir and possible personal

injuries.
