This section includes information on fuse replace- ment, line voltage selection, calibration and trouble- shooting.

Place the LLO command byte on the data bus. Disconnect the signal from the instrument. Thus, the delay period is essentially a manuzl nel settling time to allow signals to settle before each measurement. The number of readings equals the number channels per scan sequence times the number of scan sequences.

For normal non-scanner operation, the display still up- dates while the filtering process is still going on. Thus the dynamic measurement range of keithkey instrument is -6,06V to OV, which is stillcounts.

This diminishes arc protection and creates a hazardous condition. To change to a different measuring function, simply press the desired function button. To change the default frequency setting, first select the desired frequency and then use the save setup program or send LI over the bus to save the new frequency set- ting.

oeithley De-energize the circuit using the installed connect- disconnect device. Press NEXT to initiate the test. For a different address, you would of course change the corresponding digits in the programming statement.

Disable zero, if presently enabled, by pressing the ZERO button. Reading Interval Operation 1.

With select interval, use the data entry keys to program the storage interval in the range of 25msec to The following paragraphs outline the general procedures for using scan. For proper operation, the pro- grammed pole mode must agree with the pole configura- tion discussed in paragraph 2. F3X select DCA function. Determining Q— The Q of a tuned circuit can be deter- mined as follows: The value command may take on either of the following forms: Program Model Operating Modes You can program instrument operating modes by sending the appropriate command, which is made up of an ASCII letter representing the command, followed by a numeric parameter for the command option.

If we app- ly the 1. If the zero feature were used to zero the display, the counts of offset would be subtracted from Vi, resulting in an emor of counts in the displayed reading. See keithey graph 6. Its purpose is to direct the Model to execute other device-dependent commands such as F function or R range.


Readings will continue to update the display while the filter is settling, but the display will not represent the final, filtered reading value until FLTR stops flashing when the proper number of readings have been averaged. Thus, for an average-responding meter, a correction factor must be designed in. Krithley Resistance Measurements A baseline level can be established for any or all measure- ment functions and is remembered by each function.


Channels 2 through 8 referenced to Channel 1. As long as the readings are within this window, the displayed value is based on the average of the most recent number of integrations.

Programming Example— Type in the following statements to place the instrument in the correct trigger mode for pur- poses of this demonstration: Use Kelvin test leads or shielded test leads.

Ieee Bus Calibration Use uprange or downrange to scroll through locations, as required. Z2 Power Up Sequence -. The A symbol on the instrument denotes that the user should refer to the operating instructions in this manual.
