Function Indicators— The indicator or indicators that are on identify the measurement function presently selected.

IEEE address is programmable from the front panel. The following equation can be used to kfithley the voltage reference: The filter status, resolution, and selected function affects the overall reading rate, and thus the minimum interval that can be used.

Now enter the following statements kanual the computer: The unit will open the presently selected channel and then dose the new channel break before make. The following paragraphs discuss two such amplifier tests-gain and bandwidth testing. To save instrument setup conditions, press NEXT.

Exceeding this value will cause an overflow error. Programming Example — Place the instrument in the ohms function by pressing the OHMS button and enter the following statements into the computer keyboard: If data store has no valid data to display, the unit will display the following message upon entry to maanual recall mode.

Detailed instructions for all programmable functions are included; however, infor- mation concerning operating modes presented elsewhere is not repeated here. Maunal Kelvin test leads or shielded test leads. Input connections for 2-wire ohms measurements are shown in Figure and The L command keithleyy are as follows: Do not zero this level out. REV r Displays current software revision level. However; a size of indicates that the storage cycle wifi continue even after all readings are stored.

Front panel terminals are selected with the switch out, while rear-panel terminals are selected with the switch in. If a data store 19 larger than readings is pro- grammed, the following message will be displayed: Quick disconnect screw terminals, 14 AWG maximum wire size. The ZERO indicator will turn on and the display will zero.

The allowable range for the trigger delay period is between 0 and Press NEXT to program the ratio and return to normal display. Press NEXT to complete interval programming once the desired interval is keyed in.

The current reading will not be aborted and the error triggers will be buffered to re-trigger the unit when “it is ready. To make resistance measurements, proceed as follows: Two-Terminal Resistance Measurements Table An explana- tion of each error can also be found in paragraph 3.

Press NEXT twice to return to normal display.

Note that the programmed interval also mabual the inter- val between readings, and scan interval. To remove each block from the card, simply pull on the attached handle until it comes free of the card. Now, enter the follow- ing statements into the computer: After the channel limit has been selected, the instru- ment will return to normal display and begin the scan sequence with channel 1. Use uprange or downrange to select the desired inter- val type, select or default, then press NEXT.

The two filters include the inter- nal fitter and the front panel filter, as described below. The shield outer part of the connector is connected to digital common.

If the meter is connected to a high energy circuit when set to a current range, low resistance range or any other low impedance range, the circuit is virtually shorted.

Place the SDC command byte on the data bus. The secondary func- tion of this key is to enter the number mnual. For the STEP mode, one channelper interval will be scanned and stored, while in the SCAN mode, one set of channels per trigger will be scanned and stored. For example, if you program a SOOmsS: Consequently, kkeithley primary address of your Model and any other devices on the bus, for that mat- termust be the same as the primary address specified in the controller’s programming language, or you will not be able to program instrument operating modes and ob- tain data over the bus.

Plug the hne cord into the rear panel power jack and plug the other end of the cord into an appropriate, grounded power source. Switching back and forth between functions will not affect the unique configuration of each function.
