The Model 2560A is a simple, precise and cost effective solution for calibrating DC measuring instruments such as analog meters, thermometers, temperature transmitters, data loggers and multimeters.
The 2560A features high-precision DC sourcing capabilities, versatility for several test applications, and a simple, easy to use interface.
DC Calibrators feature highly accurate and stable outputs, allowing them to be used as trusted references during instrument validation or correction
Wider output ranges replace the need for using multiple calibrators with a standalone, convenient package
Perfectly suited for verifying data loggers, temperature controllers, thermometers, and multimeters, as well as analog panel meters
User-configurable settings for ramp and step functions, as well as deviation controls for verifying hysteresis
Features swicthes and dials for quickly and easily adjusting voltage, current, resistance, or thermoelectric force
Seven segment LED dsiplays provide clear visibility
Built-in interface for integration into an automated test system
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.
