Page 101: Offset Error
Front-Panel Operation Introduction to Offset, Scale, and Linearity Errors 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.
Page 102: Linearity Error
The error value is computed relative to the selected full-scale point. The formula for linearity error is: (Nominal setting) – (Adjusted 5730A Setting) Linearity Error= (Nominal Full Scale) Where the “nominal setting”...

The Offset selection can be used when in the dc voltage or current function any time it is necessary to offset the 5730A Calibrator output by a fixed amount. The Offset selection is shown by touching the + icon on the right of the display above the bottom row of selections.
Page 105: 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 106: Linearity Check With Offset And Scale
Operators Manual 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.

Page 125: Introduction
GPIB (IEEE-488) Interface Use the IEEE-488 Port for Remote Control The 5730A Calibrator is fully programmable for use on the IEEE Standard 488.1 interface bus (IEEE-488 bus). The interface is also designed in compliance with supplemental standard IEEE-488.2. Devices connected to the bus in a system are designated as talkers, listeners, talker/listeners, or controllers.
Page 126: Bus Setup Procedure
Operators Manual Bus Setup Procedure To set up the 5730A Calibrator on the IEEE-488 bus, only a choice of address and the connection to a controller is necessary. To set up the bus: 1. With the Calibrator off, attach the IEEE-488 cable to the rear panel IEEE-488 connector.
Page 127: Bus Communication Overview
RS-232 Serial Interface Use the RS-232 Port for Remote Control This procedure is intended for those who use the 5730A Calibrator serial interface for remote control from a terminal or computer with a serial interface. This section describes how to set up the RS-232 interface for remote control with protocol similar to IEEE-488.
Page 128: Rs-232 Interface Specifications
Refer to the specifications for the peripheral device, and proceed as follows to set up the serial interface for the application: 1. With the 5730A Calibrator power off, connect a 9-pin D subminiature RS-232 null- modem cable such as Fluke accessory RS43 to the rear panel RS-232 connector and to the peripheral device.
Page 129: Serial Remote Control Setup Procedure
5. Touch Exit to exit the Setup Menu. Exceptions for Serial Remote Control When the RS-232 port is used to remotely control the 5730A Calibrator, either interactively with a terminal or under computer control, operation is the same as with an IEEE-488 controller connected to the IEEE-488 port for control.
Page 130: Ethernet Interface
An internet (IP) address is necessary for all internet and TCP/IP communications. If DHCP is enabled, the 5730A Calibrator will use the dynamic address supplied by the DHCP server. If the DHCP server fails to supply the address, the IP address will be shown as "0.0.0.0".
Page 131: Set A Static Internet Address
*RST command. Configure the General Network Socket Port In order to communicate with each other, a client computer and the 5730A Calibrator must use the same socket port number. The default port is 3490. Typically, the default port does not need to be changed. If the socket port must be changed, enter the Socket Port number supplied by the network administrator.
Page 132: Configure The Lan Default Gateway
The default gateway IP address is the IP address of a gateway (router) attached to the same network as the device. When the 5730A Calibrator detects that a client computer is not on the same network (using the network number), the data is sent through the gateway to reach the host computer.
Page 133: Establish An Ethernet Connection
Establish an Ethernet Connection Establish an Ethernet Connection Telnet is the easiest method of establishing an Ethernet connection with the 5730A Calibrator. Telnet is a client-server protocol, based on TCP. The Telnet Protocol provides a fairly general, bi-directional, eight-bit byte oriented communications method. Telnet is available on all UNIX servers and on most PCs.
Page 134: Use Of Usb 2.0 Remote Control
3. Touch USB. 4. Touch Exit to exit the Setup Menu. When the USB port is used to remotely control the 5730A Calibrator, either interactively with a terminal or under computer control, operation is the same as with an RS-232 controller connected to the RS-232 port for control.

Page 199: 5730A Calibration
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 saved to a file through the USB host port on the front of the Calibrator, or send them to a computer through either the serial port, USB device port, Ethernet port, or the IEEE-488 port.
Page 200: 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.

Operator Maintenance and Calibration Calibration 3. Touch Run DC Zero to start the dc zeros routine. The status of the dc zero calibration is shown as the Calibrator progresses through a series of steps. When completed, the Calibrator shows “Calibration complete”. Note If the Calibrator is not warmed up, the display prompts to continue or cancel the DC Zeros function.

Disconnect the 10 kΩ standard, and connect the Calibrator to the 1 Ω standard. Enter the true value of the 1 Ω standard. If the standard is not between 0.9 Ω and 1.1 Ω, an error message appears, and the user can start over from this point with another standard.
Page 206: Range Adjustment
Range adjustment is accomplished by adjusting a range constant, which is an additional gain multiplier. Although range calibration is not needed in order to meet total uncertainty specifications, they are useful for tuning the 5730A Calibrator so that its values are closer to in-house standards.

Appendix C Glossary adc (analog-to-digital converter) A device or circuit that converts an analog voltage to digital signals. absolute accuracy Accuracy specifications that include the error contributions made by all equipment and standards used to calibrate the instrument. Absolute accuracy is the number to compare with the UUT for determining test specification ratio.
Page 252 5730A Operators Manual calibration check A fast, simple, automated procedure to provide added confidence between calibration recalls, and data that can be used to develop a history of Calibrator performance between calibrations. No changes are made to stored constants, and the internal check standards are used as the reference points instead of external standards as in the routine calibration procedure.
Page 253 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 254 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 255 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 256 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 257 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 258 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 259 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.
