The 2560A features high-precision DC sourcing capabilities, versatility for several test applications, and a simple, easy to use interface.
The 2560A Precision DC Calibrator offers high voltage and high current generation and intuitive operation for the analog meters calibration.
With output ranges of 100 mV to 1000 V and 100 µA to 30A, plus 10 different types of Thermocouples and Pt100 RTD, the 2560A can effectively solve the calibration requirements for DC Analog Meters and various temperature measuring instruments and controllers.

*In the high resolution mode
DC voltage: −1224.00 V to +1224.00 V
DC current: −12.2400 A to +36.720 A
5 voltage ranges (100 mV, 1 V, 10 V, 100 V, 1000 V)
7 current ranges (100 μA, 1 mA, 10 mA, 100 mA, 1 A, 10 A, 30 A)
The maximum output is ±122.4% of range. An instrument’s 1200 V range can be calibrated.
To generate higher current than 36.72 A, two 2560As can be connected to double the output to 73.44 A.
Using the output divider and deviation
Calibrating two or more points is quick and simple. It is only necessary to preselect the number of required calibration points with the lower divider control and then use the upper control to step the output to the next calibration point. The deviation settings will then enable the output value and error of each calibration point to be displayed directly.
The deviation preset control can be used to move the output value in small increments (2 or 5% of the step between calibration points).
This means that it is possible to finely approach the target calibration point, either from a lower value or a higher one, without exceeding it. This is particularly useful when the friction (hysteresis) of the moving part needs to be taken into consideration. In this case the point is calibrated twice, once from a lower value and once more from a higher value and the final calibration result is the average of the two.
Needle sticking tests can be performed with high repeatability. It is possible to stop at any point and sweep around it in fine detail.
In the high resolution mode up to 6.5 digits, it is possible to test and calibrate digital multimeters and resistance standards.
*Sweep, divider, and deviation are not available in high resolution mode.
10 types of thermocouples and Pt100
The 2560A can calibrate and test temperature controllers and data loggers which use thermocouples and RTDs. 10 types of IEC thermocouple are supported. By setting a temperature value, the emf (electro-motive force) equivalent to the temperature is generated. A wide range of temperature controllers can be calibrated due to the high accuracy.
When using a Pt100 RTD, a set temperature value generates the equivalent resistance value. Calibration using the resistance value can also be performed by setting resistance instead of temperature.
RJC at output terminals
The 2560A has 3 RJC (reference junction compensation) modes. The “internal RJC mode” uses the output terminals of the 2560A as the reference point. The “External RJC mode” enables the user to choose a suitable Pt100 as a versatile external sensor. The “Manual RJC mode” enables a reference value to be manually entered.
|Reduced energy, emission of CO2, NOx and SOx about 66% compared to the previous model.
