High Performance and Functionality in a Compact Body

n High Accuracy and Long Stability

The highest accuracy in the portable class achieved with a
silicon resonant sensor

The CA700 employs a silicon resonant pressure sensor with which Yokogawa
has achieved the highest accuracy in the portable class of a 0.01% of reading
for pressure measurement and 0.015% of reading for current and voltage

measurement. This calibrator is ideal for input and output testing of differen­tial pressure and pressure transmitters in that it correctly measures the input
and output accuracy and calculates the error rate.

n Rangeability

Has the highest resolution and the widest range in its class

The CA700 has achieved a resolution of 0.001 kPa (200.000 kPa range)
which is 10-fold higher than that of general field calibrators. The excellent
sensing characteristics of a silicon resonant sensor make it possible to

achieve a very wide range and enable one CA700 calibrator to replace
multiple field calibrators.

n User Support

Strong support for field calibration and maintenance work

Calibration procedures for differential pressure and pressure transmitters

are embedded, so routinely used as 50-percent step, up-and-down, 5-point
calibration and 25-percent step, up-and-down, as well as 9-point calibration
can be performed right out of the box. Calibration operation can be sped up

by following the navigation instructions, resulting in increased efficiency of

field work. Measurement data is automatically recorded to the calibrator so it
can be saved to a USB memory stick or transferred to a PC as text data using
a USB cable. Input and output values, error rate, date and time, and pass or
fail can be displayed on a PC monitor.

Silicon Resonant Sensor

n Field Use

IP54 waterproof and dustproof robust case enables use of
this calibrator in harsh environments

Calibration of pressure transmitters is usually carried out in harsh environ­ments where there are many pipes and handrails or in wet areas. The CA700

has a robust case designed according to the IP54 waterproof and

dustproof standards. A shoulder strap can

be attached to the calibrator to make
it easy to carry around in the field. In
addition, an easy-to-read LCD and tilt
stand suitable for outdoor work exposed
to direct sunlight extend the range of

use of this calibrator from indoor bench
use to outdoor field use.



20 mA SIMULATE (Two-wire Transmitter Simulator)

The CA700 can also be used as a tr ansmitter simulator to carry out a loop test. It
can absorb (SIN K) the set current from an ex ternal voltage generating device (e.g.,
a distributor system or PLC) of instrumentation equipment. 4-20mA current can be
sourced with an accur acy of 0.015% of the reading.



Two-wire Transmitter Loop Check

DC mA signals can be measured by supplying power to the transmitter from a 24 V
DC power supply. DC mA signal measurement and zero-point check can be
performed with an accuracy of 0.015% of the reading. A 250-ohm resistor for
HAR T and BR AIN communication is included in this calibrator so there is no need to
attach an external resistor when connecting to a handy terminal.



Field Calibration of Differential Pressure and Pressure Transmitters

Calibration of pressure transmitters is required to accurately measure the input and
output values and to calculate the error rate.
The CA700 ensures reliable calibration with its function to accurately measure the
input and output values of pressure and current. Additionally its embedded
calibration procedures enable users to perform certain calibration following the
prescribed procedure.



Input Command Check and Adjustment of Recorders and Controllers

Instrumentation loop test and operation/command check can be performed by
sourcing DC 1-5 V / 4-20 mA ins trument ation signals with an accuracy of 0.015%
of the reading. Furthermore, t wo patterns of linear sweep and step sweep can be
selected (the sweep time can be specied from 15, 30, 45, and 60 sec).



Check and I/O Adjustment of an Electro-pneumatic Converter

Input and output adjustment of an electro-pneumatic
converter is carried out by applying rising and falling
currents of 0, 25, 50, 75, and 100% of the span. A
reliable test can be car ried out with the CA700 that
has a 4-20 mA step function for signal generation
and a capability to accurately measure the
generated pressure.



Pressure Switch Test

A pressure switch test measures the pressure at the time when the contact opens
and closes and the resistance at the time when the dead band contact closes.
A test procedure is embedded to enable users to carry out a test following the
prescribed procedure.
