Appendix 2 Example of Meter and Transducer Calibration
Calibrating a Meter Whose Range Is –10 V to +10 V
Similar to “Calibrating a 4-20 mA Meter” on the previous page, using the SCALE switch and main
setting dials, set the scale’s main setting (MAX) to +10 V and main setting (MIN) to -10 V. Then,
calibrate each point. For details on 2560A configuration, see chapter 5 and sections 7.1 and 7.2.
Calibrating a Transducer
Temperature converters can be calibrated including their linearity.
For a temperature converter whose input is thermocouple type K (–200°C to +800°C) and output is
voltage (–10 V to +10 V), set the scale’s main setting (MAX) to +800°C and the main setting (MIN) to
–200°C. Set the output divider’s denominator m to 10. Vary the numerator n from 0 to 10, and check
the digital multimeter (DMM) reading connected to the output side of the temperature converter.
For details on 2560A configuration, see sections 6.1 to 6.4 and 7.1.

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
blinking changes to solid.
