Thiết bị hiệu chuẩn đa năng YOKOGAWA CA500

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).

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)
