  • Page 4: What Is In This Guide

    What is in this Guide? The Operator Guide begins with safety information, a short meter calibration exercise for new users, then continues with a condensation of information from the Operator Manual . For complete information about the Calibrator’s features, functions, and operating procedures, refer to the Operator Manual .
  • Page 5 Safety Summary (cont.) Grounding the Calibrator The Calibrator is a Safety Class I (grounded enclosure) instrument. The enclosure is grounded through the grounding conductor of the power cord. To avoid electrical shock, plug the power cord into a properly wired earth grounded receptacle before making any connections to the Calibrator terminals.

  • Page 10: Exercise: Activating Error Mode

    Exercise: Activating Error Mode Chances are the meter reads something other than exactly 10V. To quickly check the error of the meter, turn the rotary knob to obtain a meter reading of exactly 10V, and read the error off the Control Display.

  • Page 11: Exercise: Applying An Ac Voltage

    Exercise: Applying an ac Voltage There is no “ac mode” switch on the Calibrator. You change a dc output to ac by entering a frequency through the keypad and pressing To test the meter at 10V at 1 kHz, set the meter to read 10V ac, press 1 0 V, then 1 K HEO.

  • Page 12: Front Panel Features

    Front Panel Features Following is a brief description of the Calibrator’s front panel features. Output Display (Left Side) Shows output amplitude and frequency. The top line shows the active output value in up to eight digits, plus a polarity sign. The bottom line shows output frequency in five digits.

  • Page 13: Display Screen Saver

    Display Screen Saver Both the Output and Control displays blank automatically after 30 minutes of inactivity, unless the Calibrator is in one of the operating states that overrides the screen saver. If the screen saver has activated, you can restore the display by pressing C.

  • Page 14: Front Panel Keys

    Front Panel Keys Toggles the Calibrator between operate and standby modes. In standby mode, the OUTPUT binding posts are internally disconnected from the Calibrator. The Calibrator powers up in standby mode. The Calibrator automatically switches to standby mode when: • r is pressed.
  • Page 15 Front Panel Keys (cont.) Opens and closes an internal connection between the SENSE and OUTPUT binding posts. The Calibrator powers up with these two binding posts connected internally (the SENSE binding posts are open circuited), and the X indicator off. Toggling X on (so it lights) disconnects the sense lines from the OUTPUT binding posts.
  • Page 16 Front Panel Keys (cont.) Opens and closes an internal connection between the V GUARD (voltage guard) and OUTPUT LO. The Calibrator powers up with the V GUARD internally connected to OUTPUT LO and the x indicator off. Toggling x on (so it lights) disconnects OUTPUT LO from the V GUARD.
  • Page 17 Front Panel Keys (cont.) Enables or disables output from an amplifier, when it would not otherwise be automatically selected. Sets the Calibrator to standby if this selection moves the output location. When available, an amplifier is automatically selected for output settings that exceed Calibrator capabilities, but fall within the limits of the selected amplifier.
  • Page 18 Front Panel Keys (cont.) <a> These keys are the output adjustment controls. If any of these keys are pressed, or if the knob is turned, a digit on the Output Display becomes highlighted. Turning the knob adjusts the output value. An error display appears on the Control Display, showing the difference between the original (reference) output and the new (adjusted) output.
  • Page 19 Front Panel Keys (cont.) Calls up a menu that allows you to specify limits beyond which the Calibrator will not operate. This can be used to set limits that protect both operators and equipment. Changes the output to one tenth the reference value (which is not necessarily the same as the present output value).
  • Page 20 Front Panel Keys (cont.) Clears a partially completed keypad entry from the Control Display, or clears an error message that required acknowledgment, If there is a partially completed entry when C is pressed, the output is unaffected. This key is only active during error mode operation.
  • Page 21 Front Panel Keys (cont.) Loads a newly keyed-in output value showing on the Control Display into the Calibrator. If you press E without identifying the units for the entry, the Calibrator keeps the units (except Hz) that were last used. This allows you to alter values for a function without keying in the units every time.
  • Page 22 Front Panel Keys (cont.) 0 - 9 (Numeric Keypad) Used to enter the digits of the output amplitude and frequency, as well as other data such as the time and date. The proper sequence for entering a value is to enter the digits, then any necessary multipliers, an output function key, then E.

  • Page 23: Front Panel Connectors

    Front Panel Connectors WIDEBAND Connector A type “N” connector that provides a connection point for output from the -03 Wideband AC option. Wideband output specifications are stated for output levels present at the end of its three-foot 50Ω coaxial cable terminated into a 50Ω purely resistive load.
  • Page 24 Front Panel Connectors (cont.) SENSE Binding Posts Used in the resistance and voltage functions for sensing at the UUT after you have selected external sense by toggling the X key on, or by remote command. External sensing should be used in the dc voltage function when the UUT draws enough current to produce a significant voltage drop in the cables, and in the resistance function when the UUT has a...

    Provides the analog and digital interface for the Fluke 5725A Amplifier. 5205A AMPLIFIER Connector Provides the analog and control interface for either the Fluke 5205A or 5215A Precision Power Amplifier. 5220A AMPLIFIER Connector Provides the analog and control interface for the Fluke 5220A Transconductance Amplifier.
  • Page 26 Rear Panel Connectors (cont.) PHASE LOCK IN BNC Connector Provides the input for an external signal onto which the Calibrator can be phase locked (1V to 10V rms, 10 kΩ input impedance). The connector shell is not connected directly to chassis ground; it is connected internally to the OUTPUT LO binding post.
  • Page 27 Rear Panel Connectors (cont.) The OUTPUT, SENSE, and V GUARD binding posts on the rear panel are alternative connections to the UUT. An internal cable enables either the front or rear binding posts. The procedure to disable the front panel binding posts and enable the rear panel binding posts involves opening the cover of the Calibrator, which should only be done by authorized service personnel.
