Instrument Properties

This properties window is available by clicking ... in the right-most column on the Configure Instruments tab (Connected Mode only). This window contains these five tabs:

Firmware Version

This tab displays:

Module Wiring Mode (34980A Only)

34923A and 34925A multiplexer modules and the 34933A matrix module can be set to either 1-wire or 2-wire mode; the other multiplexer and matrix modules have a fixed, 2-wire mode.

This tab allows you to check or change the wiring mode for 34923A and 34925A modules. The Wiring Mode column lists the wiring mode for each module (either 1-wire or 2-wire). The Matches Configuration column shows whether the 34923A and 34925A module(s) match the wiring mode established in the configuration. (Module mismatches can occur when modules have been replaced by similar modules set to a different wiring mode.) The Matches Configuration column will show either:

 

Changing the Wiring Mode

Do the following to change the wiring mode for a 34923A or 34925A module.

  1. Click the word 1-Wire or 2-Wire in the Wiring Mode column next to the 34923A or 34925A module.
  2. Click the down arrow and select the new wiring mode.
  3. Click the Apply button to change the wiring mode.
  4. Since a wiring mode change requires the 34980A to be rebooted, you will receive a message asking whether or not to proceed. Click Yes to proceed or No to cancel the change.

Relay Odometer

The instrument has a Relay Maintenance System to help you predict relay end-of-life. The instrument counts the cycles on each relay in the instrument and stores the total count in non-volatile memory on each switch module. You can use this feature on any of the relay modules.

 

HW Alarm

The instrument provides four hardware alarm outputs. You can use the alarm output lines to trigger external alarm lights, sirens, control ovens, and so on. Alarms are associated with limits and are configured for each channel in the scan list in the Channel <channel number> Limit Settings dialog box.

On the HW Alarm tab, you can set the alarm characteristics and apply them to the instrument or clear the alarm settings in the instrument as follows:

  1. Select an alarm (or ALL alarms) in the Select Hardware Alarm: column.
  2. Select either Latch on Failure or Tracking in the Mode area (the selected mode is used for all four outputs).
  3. Select the slope of the output pulse in the Polarity area. (the selected Polarity is used for all four outputs). In the Fail = Low mode, a high to low TTL transition (falling-edge) is output to indicate an alarm. In the Fail = High mode, a low to high TTL signal (rising-edge) is output to indicate an alarm. A Factory Reset resets the Polarity to Fail = Low.
  4. To restore the default values, click the Restore Defaults button. To clear the alarm settings for the selected alarm(s) click the Clear from Instrument button. When finished, click the Apply to Instrument button to store these settings in the instrument.

Note: Changing the slope of the output lines may cause the lines to change state.

 

Instrument State

You can store the current instrument state in one of five non-volatile storage locations. These states are initially named STATE1 through STATE5. You can rename these states.

You can also select from three predefined states Last Power Down, Factory Reset for 34980A and Factory Reset for 34980A.

To store the current instrument state, click on one of the first five state names and then click the Store Current State button.

To edit a state name, click on one of the first five state names and then click the Edit State Name... button. Enter the new name and click OK.

To recall a state, click on one of the eight state names listed and then click the Recall Stored State button.

 

Miscellaneous

This tab displays the date and time settings for the instrument and the PC, controls the instrument's front panel and the Autozero mode.

Date/Time Settings

This section displays the date and time settings for the instrument and the PC.

Click the Set Instrument to PC Clock button to synchronize the instrument's date and time setting to that of the PC. This is useful when doing timed starts and stops for scans.
