Page 64: Offset Error
5730A Operators Manual Offset Error Offset error can be measured directly by finding the Calibrator output that causes a meter reading of 0 V. This error is called an offset because it reflects a fixed error that is present in all meter output readings. For example, if a meter reads 0 V when -1.3 mV is applied, the meter has an offset error of +1.3 mV.

Page 68: Program A Scale Factor
“Linearity Checking With Offset and Scale”.) To program a scale factor: Set the 5730A Calibrator to output a level just below the UUT full-scale endpoint. For example, use 19.9 V for a UUT that ranges at 20 V. Adjust the Calibrator output with the rotary knob (and arrow keys if necessary) until the UUT reads the selected correct output level (19.9 V in this example).
Page 69: Linearity Check With Offset And Scale
Linearity Check with Offset and Scale Linearity Check with Offset and Scale With the 5730A Calibrator offset and scaling features, a UUT offset and scale errors can be removed to isolate and display linearity error. The subsequent procedure is an example that uses the Offset and Scale selection to determine both scale and linearity error of a 4 1/2-digit DMM.

When finished with artifact calibration, but before the new constants are saved, the 5730A Calibrator presents the proposed adjustments as +/- ppm of range and percentage change in specification for each range and function. A list of changes can be sent to the computer through the serial port, USB device port, Ethernet port, or the IEEE-488 port using the remote command: CAL_RPT? CHECK.
Page 161: Establish Traceability
Calibration Reports The 5730A Calibrator stores two sets of calibration constants: the set currently in use and the old set from the previous calibration. This gives the Calibrator the ability at any time to produce a calibration report of the differences between the present settings and the settings that were in effect before the last calibration.

Page 211: C Glossary
The frequency range of human hearing; normally 15 Hz - 20,000 Hz. artifact standard An object that produces or embodies a physical quantity to be standardized, for example a Fluke 732B dc Voltage Reference Standard. base units Units in the SI system that are dimensionally independent. All other units are derived from base units.
Page 212 A device used solely to verify the integrity of another standard. For example in the Calibrator, one Fluke RMS sensor continuously monitors the output voltage while a second Fluke RMS sensor confirms the integrity of the first. characterization The development of a table of calibration constants or correction factors for use in correcting the output or reading of an instrument.
Page 213 Appendices Glossary current guard A generator that drives the inner shield of a triaxial cable with a signal of the same amplitude and phase as a Calibrator’s ac current output signal on the center conductor. The current guard shields the Calibrator’s output signal from a capacitive leakage path to ground.
Page 214 5730A Operators Manual ground The voltage reference point in a circuit. Earth ground is a connection through a ground rod or other conductor to the earth, usually accessible through the ground conductor in an ac power receptacle. ground loops Undesirable currents induced when there is more than one chassis ground potential in a system of instruments.
Page 215 Appendices Glossary MTTF (Mean Time to Fail) The time interval in operating hours that can be expected until the first failure of equipment. MTF can be calculated from direct observation or mathematically derived through extrapolation. MTTR (Mean Time to Repair) The average time in hours required to repair failed equipment.
Page 216 5730A Operators Manual random error Any error which varies in an unpredictable manner in absolute value and in sign when measurements of the same value of a quantity are made under effectively identical conditions. range The stated upper end of a measurement device’s span. Usually, however, a measurement device can measure quantities for a specified percentage overrange.
Page 217 Appendices Glossary rf (radio frequency) The frequency range of radio waves; ranging from 150 kHz up to the infrared range. rms (root-mean-square) The value assigned to an ac voltage or current that results in the same power dissipation in a resistance as a dc current or voltage of the same value. rms sensor A device that converts ac voltage to dc voltage with great accuracy.
Page 218 5730A Operators Manual standard A device that is used as an exact value for reference and comparison. standard cell A primary cell that serves as a standard of voltage. The term “standard cell” often refers to a “Weston normal cell”, which is a wet cell with a mercury anode, a cadmium mercury amalgam cathode, and a cadmium sulfate solution as the electrolyte.
Page 219 Appendices Glossary true value Also called legal value, the accepted, consensus, (for example, the correct value of the quantity being measured). uncertainty The maximum difference between the accepted, consensus, or true value and the measured value of a quantity. Uncertainty is normally expressed in units of ppm (parts per million) or as a percentage.
