2. Short Overview
2. Short Overview
The CPD8500 digital deadweight tester is a digital primary pressure standard, which combines the metrological performances of
traditional deadweight testers with the convenience of digital interface and transfer standards. It can be used to calibrate a variety
of precision pressure devices such as pressure controllers, calibrators, indicators and transducers in either absolute or gauge
pressure modes. The CPD8500 has two different chassis and multiple head options to cover absolute and gauge pressure types
with a high accuracy class.The optional internal or external barometer allows easy zeroing and pressure type emulation.
The CPD8500 digital deadweight tester’s measuring principle lies in the fundamental equation defining pressure:
P = F / A
It is based on the connection of a piston-cylinder assembly, whose surface area A is perfectly known, with a high accuracy
electronic measuring cell, which measures the force F.
Pressure is applied on the piston, which turns it linearly into a perfectly proportional force that is transferred to the measuring cell.
The measuring cell permanently measures the pressure-generated force. It uses the force applied and creates an imbalance in a
magnetic field. The electrical power generated to restore the magnetic field’s balance is interpreted by a microprocessor to display
a stable pressure value.

2.2 Components
2.2.1 Base
The base is composed of:
■The measuring load cell, which measures the force applied by the head
■The Environmental Monitoring Module
■The electronic assembly which ensures stable pressure calculation, the display as well as remote communication
■Optional internal barometric reference for pressure emulation
■Precision vacuum sensor (absolute base only) for detection of stable vacuum pressure
■The lubrication valves to automatically switch the lubrication circuit of the measuring head from atmospheric pressure to the
measured pressure
2.2.2 CPS8500 Measuring Head
The measuring head CPS8500 is designed for containing, operating and protecting the piston-cylinder assembly. The measuring
heads are designed to operate with pure gas with the piston cylinder being lubricated with gas only for absolute versions and gas
or oil (depending on the range) for gauge versions. The measuring heads are available in various versions:
■Model 610 - absolute head
■Model 110 - low pressure gauge head
■Model 111 - medium pressure gauge head
■Model 410 - high pressure gauge head
Each measuring head is characterized by a nominal coefficient, Kn. This is a conversion factor specific to each measuring head,
representing the pressure value per kilogram converted in proportion to the head’s cross sectional area.This conversion factor is
either represented in bar/ kg or psi/kg.
2.2.3 Environmental Monitoring Module
The Environmental Monitoring Module (EMM) accurately detects the ambient conditions and provide feedback to the electronic
assembly inside the Base for easy adaptation of measurements corresponding to any changes in ambient conditions. The EMM
consists of an ambient pressure, temperature and relative humidity sensor. The EMM continuously monitors the change in ambient
conditions in real time.Whenever these conditions vary in proportions that might noticeably alter the measuring performance, the
CPD8500 recommends the user to perform a span calibration for the internal load cell, this is explained in section 6.4.1.4.
2.2.4 Drive Motor
Stable pressure measurement requires the piston-cylinder assembly inside the measuring head to spin at a fixed rate.The
CPD8500 supports either a brushed DC or a brushless DC motor.
2.3 Turning On
Apply power to the power connector on the rear of the base of the instrument with the included power cord, remove any plastic
plugs from the rear panel pressure ports, and press the power switch to ON.The system will go through an initialization process,
which takes about 1 minute, and then a display will appear similar to the screen shown below.
Power Switch ON/

4. Transport, Packaging and Storage
4.1 Transport
Check the digital deadweight tester model CPD8500 for any damage that may have been caused by transport.
Obvious damage must be reported immediately.
CAUTION!
Damage through improper transport
With improper transport, a high level of damage to property can occur.
▶When unloading packed goods upon delivery as well as during internal transport, proceed carefully and observe
the symbols on the packaging.
▶With internal transport, observe the instructions in chapter 4.2 “Packaging and storage”.
If the instrument is transported from a cold into a warm environment, the formation of condensation may result in instrument
malfunction. Before putting it back into operation, wait for the instrument temperature and the room temperature to equalize.
4.2 Packaging and storage
The CPD8500 digital deadweight tester is packaged in a custom transport case especially designed to maintain the performances
