제품정보

  • The CA500 and CA550 are high-performance, multi-function calibrators designed for use in multiple applications. Featuring useful functions for field work, these multi-function calibrators help you calibrate field instruments with improved source and measurement accuracy.

    Two models are available, offering two different levels of accuracy:

    The CA500 achieves an accuracy of 0.015% (DC current), 0.020% (resistance), and 0.3˚C (RTD).
    The CA550 achieves an accuracy of 0.010% (DC current), 0.015% (resistance), and 0.1˚C (RTD).

제품상세정보


Multi-function

  • Sources and measures DC voltage, DC current, RTD, TC, resistance, frequency and pulse signals
  • Corresponds to 17 types of TC standard (JIS/IEC/DIN/ASTM/GOST R)
  • Corresponds to 14 types of RTD standard (JIS/IEC/GOST R)

Multiple source patterns

Linear sweep function
Continuously Source from 0% to 100%

Step sweep function
Change output in a staircase (step) pattern by specifying the number of steps. (The number of steps can be set from 2 to 20)

Program sweep function
Users can set the desired output value (%) and number of steps. (10 steps for CA500, 20 steps for CA550)

Functions

Automatic input/output testing *CA550 only
(Program sweep)

Automatic input/output testing is possible by setting source values for each step for a calibration target. Calibration results such as generated value, measured value, error rate, date/time, and pass/fail are saved in CSV format in the CA550 main unit.

By connecting the CA550 to a PC using a standard USB cable, the instrument can be recognized as a mass-storage device for data to be transferred to the PC.

HART Communication Protocol *CA550 only

Version update will be available in June, 2020.(Free)

The following items are supported by HART communication function:

  • TagNo.
  • PV value (including reading of PV %value, AO value, SV value, TV value, QV value)

Read

  • LRV (Lower limit of range)
  • URV (Upper limit of range)
  • Damping

Read and Write

  • Trimming of 4 mA
  • Trimming of 20 mA

Write

*Please note that not all commands are supported by HART communication.
*TagNo acquisition function is available in BRAIN communication. No other functions are available.

Easy-to-view DisplayEasy-to-view Display

CA500 features a Reflective LCD, providing improved outdoor visibility. Main display (generated/measured values) and Sub display (%, mV, &Omega, etc.) allow required information at a work site to be confirmed at a glance.

Wiring information display functionWiring information display function

A wiring diagram is displayed according to the function selected. This function allows a user to perform wiring while referring to a wiring diagram and prevents mis-wiring.

Thermocouple generation using TC Mini PlugThermocouple generation using TC Mini Plug

Using a TC Mini Plug together with a compensating lead wire enables generation of thermal electromotive force without an external RJ sensor.*
* A compensating lead wire needs to be prepared by customer.

Easy-to-use key operation

Easy-to-use key operation0%/100% keys
The source can be easily switched between 0% and 100% of range. Users can also set a desired value.

UP/DOWN keys
The output is changed in preset steps by pressing UP or DOWN key.

Operation key layoutOperation key layout
Keys related to generation and measurement are arranged collectively to allow easy and intuitive operation.

SQUARE ROOT outputSQUARE ROOT output

For 4-20 mA, 1-5 V ranges, users can choose between LINEAR and SQUARE ROOT output.

Applications

20 mA SIMULATE

The CA500 series can be used as a transmitter simulator to perform a loop test. It sinks the set current from an external voltage source of instrumentation equipment.

20 mA SIMULATE

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 0.01% of reading (0.015% of reading for CA500).Two-wire Transmitter Loop Check

?

Zero point adjustment of HART transmitter

CA550 supports HART communication (Universal command/Common practice command).
Reading of HART device information, writing of LRV/URV, and trimming of analog output are possible.

TC SIMULATE

The CA500 series corresponds to 17 types of TC for sourcing. It achieves the high basic accuracy of 0.5°C (typical of type K), two times better than the previous model.
Also, input/output testing is possible with a single CA500/CA550, as it can measure output signals.

TC SIMULATE

RTD SIMULATE

CA500/CA550 corresponds to 14 types of RTD for sourcing. It achieves a high basic accuracy of 0.1°C* (typical of type Pt100), which enables it to operate a highly reliable test.
Additionally, input and output testing of temperature transmitters is possible at the same time.

Pulse SIMULATE

This calibrator performs measurement of pulse signal integration from a flowmeter and generates a pulse to a receiver, such as integrating counter or pulse converter. Integration time can be set from 1 min to 60 min.
