    The 2560A does not use relays to invert the polarity for ranges other than 1000 V and 10 A, so glitches due to polarity switching do not occur. The control system on the isolated side is surrounded by a guard potential to suppress the effects of common-mode noise.

  • Page 185 Output Note For temperature, the source range of the positive side of the 2560A and that of the negative side are different. When setting main setting (MAX) and main setting (MIN), if the source range is exceeded as a result of changing the polarity, the main setting and polarity blink. If you turn any of the main setting dials in this condition, the main setting is set to the maximum absolute value within that polarity’s source range, and...

    Write the user-defined data from a definition file to the 2560A using the USB mass storage feature. Before the data is written, the 2560A checks for errors in the data. If there are no errors, the data will be written to the 2560A’s internal memory. If data is already written, it is updated. If there is an error, the contents in the internal memory will not be updated.
