Description
Used in conjunction with the ENTRY keys to select a channel (module) for front panel control and/or display.
- Identifies which module is installed in the selected input channel.
and 
Increment( 
) and decrement ( 
) the channel number.
- Returns the display to the metering function. With the metering function selected, the display will show the measured input voltage and current, the computed input power, or certain status conditions (e.g. INPUT SHORT ON, OC, etc.) for the selected channel. Press the Meter key to continually step through the displays.
- Displays the selected channel’s range setting for current (C:RNG) or resistance (R:RNG), depending upon which function is selected. The settings can be changed using the ENTRY keys.
- Toggles the selected channel’s input on and off. Input Off disables the input. Input On enables the input and returns the module to the original settings.
- Toggles the selected channel’s short circuit mode on and off. Short On applies a short circuit across the input. Short Off removes the short circuit and returns the channel to the original settings. Short On is overridden by Input Off.
- Toggles transient operation on and off for the selected channel. The Tran annunciator is on while transient operation is on. Transient operation causes the module’s input to periodically switch between two levels.
- Displays the selected channel’s transient level for current (C:TLV), resistance (R:TLV), or voltage (V:TLV) depending upon which function is selected. This level can be changed using the ENTRY keys. The input alternates between the transient level (TLV) and the main level of the active mode (CURR, RES, or VOLT) when transient operation is turned on.
- (shifted Tran Level key) - Displays the selected channel’s slew setting for current (C:SLW) or voltage (V:SLW) depending upon which function is selected. The settings can be changed using the ENTRY keys. The slew settings determine the rates at which new programmed values will change. Note that resistance changes use the voltage or current slew rate settings depending upon the resistance range.
- Displays the frequency setting of the transient generator (e.g. FREQ 1000) for the selected channel. The setting can be changed using the ENTRY keys. The Freq setting determines the frequency in continuous transient operation.
(shifted Freq key) - Displays the duty cycle of the transient generator (e.g. DCYCLE 50.0) for the selected channel. The setting can be changed using the ENTRY keys. The Dcycle setting determines the TLEV portion (percentage) of the duty cycle in continuous transient operation.
