Process Calibrator CA300 Series

Step Sweep Function

Sources by 25% step automatically from 0% to 100% of span, which improves efficiency of operation. It can correspond to various response times of field devices. (15/30/45/60 seconds)

Manual Step Function

Sources by 25% step manually from 0% to 100% of span.

Linear Sweep Function

Sources continuously from 0% to 100% and is capable to check meter and make linearity tests. Sweep time can be selected by 15/30/45/60 seconds.

Span check function

Switches sources 0%↔100% by one touch. With this function, it makes it simple to make adjustment and to inspect the open and close operation of valves.

20mA SIMULATE

CA310 is capable to execute a loop check by simulating a transmitter, sinking the current signal from the external source (distributor). It achieves the high accuracy 0.015% of setting to source 4-20mA.

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 measurement and zero-point check can be performed with an accuracy of 0.015% of reading. A 250-ohm resistor for HART and BRAIN communication is included in this calibrator so there is no need to attach an external resistor when connecting to a handy terminal.

TC SIMULATE

CA320 corresponds to 16 types of TC for sourcing. It achieves the high basic accuracy of 0.5°C (typical of type K), three times better than the previous model which enables it to operate a highly reliable test. Additionally, the difference of temperature between objects can be compensated, by using external RJ sensor or a compensating lead wire.

TC MEASURING

CA320 can measure the output of TC like a thermometer. It achieves the basic accuracy of 0.5°C (typical of type K), three times better than the previous model and is for multiple use for process temperature measuring by corresponding to 16 types of TC.

RTD SIMULATE

CA330 corresponds to 14 types of RTD for sourcing. It achieves the high basic accuracy of 0.3°C (typical of type PT100), twice better than the previous model which enables it to operate a high reliable test.
