Easy-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 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 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
0%/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 layout
Keys related to generation and measurement are arranged collectively to allow easy and intuitive operation.
SQUARE 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.
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).
?
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.
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.
*Accuracy for CA550
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.
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).
