2560A HIGH VOLTAGE AND HIGH CURRENT PRECISION DC CALIBRATOR
The Model 2560A is a simple, precise and cost effective solution for calibrating DC measuring instruments such as analog meters, thermometers, temperature transmitters and data loggers
The 2560A Precision DC Calibrator offers high voltage and high current generation and intuitive operation for the analog meters calibration.
- Wide output range of voltage and current generation
- Dials and switches for each digit and function
- High accuracy, stability, and resolution
- Various effective functions for 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.

Wide Output Range
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.
Higher current output
To generate higher current than 36.72 A, two 2560As can be connected to double the output to 73.44 A.
Calibrating and testing analog meters
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.
Using the output divider and deviation preset
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.
Calibration and testing multimeters
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.
