La description

The CA300 Series is a high accuracy source and measure portable handheld calibrator used to inspect and maintain the accuracy of control devices such as temperature controllers, temperature transmitters, temperature sensors and other process devices which are used in process plants, industry machinery, and manufacturing. Available in 3 models, the CA310, CA320, and CA330 provide an ergonomic and friendly user-interface making it easy to use.
CA310 Features
Basic Accuracy: 0.015% (Source&Meas. accuracy of Voltage mA)
20 mA SIMULATE (SINK) function
Simultaneously supplies 24V loop power and measure output signal with high accuracy
HART/BRAIN comm. resistance (250&Omega,) embedded
Sub display displays span% of the source value
Corresponds to various types of source pattern (Step sweep/ Linear sweep/ Manual step/ Span check)
CA320 Features

Corresponds to 16 types of TC standard (JIS/IEC/DIN/ASTM/GOST R)
Sub display displays value of voltage source and span%
Corresponds to various types of source pattern (Step sweep/ Linear sweep/ Manual step/ Span check)
Corresponds to other TC types by mV source function
Measures TC sensor output as a thermometer
CA330 Features
Basic accuracy: 0.3°C (Typical of PT100)
Corresponds to 14 types of RTD standard (JIS/IEC/GOST R)
Sub display displays value of resistance source and span%
Corresponds to various types of source pattern (Step sweep/ Linear sweep/ Manual step/ Span check)
Corresponds to 2,3,4 wire. Realizes RTD simulation
Measures output of RTD sensor as a thermometer
Addition of Sub Display The sub display additionally shows span%, source value of voltage or resistance, while the main display shows the setting value. Corresponds to 2WAY Power Supply Power is supplied by AA Alkaline batteries or an AC Adapter''
