  • Page 5 Safety Precautions The following safety precautions should be observed before using this product and any associated instrumentation. Al- though some instruments and accessories would normally be used with non-hazardous voltages, there are situations where hazardous conditions may be present. This product is intended for use by qualified personnel who recognize shock hazards and are familiar with the safety pre- cautions required to avoid possible injury.
  • Page 6 As described in the International Electrotechnical Commis- sion (IEC) Standard IEC 664, digital multimeter measuring circuits (e.g., Keithley Models 175A, 199, 2000, 2001, 2002, and 2010) are Installation Category II. All other instruments’ signal terminals are Installation Category I and must not be connected to mains.

  • Page 7: Safety Precautions

    Do not exceed the maximum signal levels of the instruments and accessories, as defined in the specifications and operating information, and as shown on the instrument or test fixture panels, or switching card. When fuses are used in a product, replace with same type and rating for continued protection against fire hazard.
  • Page 8 Keithley Instruments to maintain accuracy and functionality of the product.) If you are unsure about the applicability of a replacement component, call a Keithley In- struments office for information. To clean an instrument, use a damp cloth or mild, water based cleaner.

  • Page 10: Operation Summary

    Non-701X series card are not detected by the Model 7002. The model number of each non-701X series card must be assigned to the slot that it is installed in.
  • Page 11 The light pen is operational when it is plugged into the front panel receptacle labeled LIGHT PEN. Display modes There are two basic display modes for the Model 7002; the relay status display mode and the list display mode. The VFD messages for the display modes are shown as follows:...
  • Page 12 List display mode In this display mode, the channel LEDs indicate which channels are included in the selected list (channel list or scan list). Table 1 summarizes the significance of the chan- nel LEDs in this display mode. If you use this display mode when creating a list, be sure to return to the relay status display mode so that you can mon- itor the real-time state (on or off) of each available channel in your switch system.
  • Page 13 LED graticule control LED Graticule control allows you to increase contrast between on and off LEDs by eliminating the dimly lit state for LEDs. With the LED Graticule disabled (off), LEDs will be either off or brightly lit. Table 1 explains the significance of the channel LEDs for the two graticule modes.

  • Page 18 Edit Keys and LEDs: Cursor ( ) — Select a channel entry by positioning the cursor on it. DELETE — Press (or click) to delete selected entry. INSERT — Press (or click) INSERT to enable insert func- tion, place cursor at desired location in list and enter chan- nel(s).
  • Page 19 Scan List. To perform a scan, first program the control- ling aspects of the scan (see Table 4), and then press (or click) STEP to take the Model 7002 out of the idle state (ARM indicator on). Regardless of how the scan is configured, the STEP key (or LED) is always active allowing you to manually step through the scan.
  • Page 20 The scan can be terminated by sending the following com- mand: :ABORt All closed channels will open and the Model 7002 will return to the idle state. Channel patterns (STORE and RECALL) Up to 500 channel patterns can be stored in memory. A channel pattern is simply a pattern of open and closed chan- nels.
  • Page 21 Storing the Current List: 1. Create a Channel List. 2. Press STORE and select CURRENT LIST. 3. Key in the memory location (1 to 500) and press ENTER. Recalling a channel pattern: Press RECALL, key in the memory location of the stored channel pattern and press ENTER.
