Different from the traditional interface, Chroma 12061 uses USB as its standard feature that not only improves the transmission speed but

also makes the connection more easier with the plug and play function.

The USB interface fully supports USBTMC (USB Test & Measurement Class). As long as the instrument is equipped with USB interface that

supports USBTMC, it can communicate with PC in real time via VISA driver without the restrictions of platform and environment. USBTMC is a communication protocol built on top of the USB and uses GPIB-like methodology to communicate with USB. Therefore, from user’s point

of view using USB should be as simple as using GPIB.

Chroma 12061 has temperature measurement function that supports 7 kinds of Thermocouples:E, J, K, N, R, S, and T type. It also

supports RTDs 4-wire measurement. The built-in ITS-90, IEC751 and Callendar-Van Dusen temperature conversion can satisfy the diverse

measurement requirements of yours.

m u lt i- p o in t s c a nn e r c a r d

Chroma 6½ Digital Multimeter supports Multi-point Scanner Card

which is a scanning measurement tool not supported by most of the

6½ Digital Multimeters in the field.

Multi-point Scanner Card offers multiplexing ten two poles (ACV,

ACI, DCV, DCI, Resistance, Period, Frequency) that can be installed

to the extension card option directly on the rear panel.
