Changing line voltages requires changing fuses. Analog output The Model has an analog output on the rear panel. AUTO Autorange enabled. Questionable reading or invalid cal step. Use a trigger link cable or adapter, such as Models , , , and Check to see that the line voltage indicated in the window of the fuse holder assem- Figure Figure is correct for the operating voltage in your area. If a failure is detected, the instrument momentarily displays an error mes Factory default settings provide a general purpose setup for front panel operation, while the bus default GPIB settings do the same for remote operation.
Refer to the section listed in the table for in-depth information. To access the menu, press the MENU key. Page Scpi Programming? A query command requests queries the pro- grammed status of that command. The Model does not internally limit the LO-to-chassis voltage.
The voltage source is primarily used for ohms measurements. Damage to the instrument may result if volt- ages greater than V are forced on the Model Input HI.
Noise and safety shields Figure shows typical measurement shielding. Exceeding 42V can create a shock hazard. If it is possible for the DUT or external supply to present more than In A , a noise shield is used to prevent unwanted signals from being induced on the picoammeter input. This test fixture will accommodate a variety of connection requirements. Figure General purpose test fixture connections The interlock prevents the voltage source from being placed in operate on the 50V and V ranges, and optionally on the 10V range, to assure safe operation.
For comprehensive information on all measurement consid- erations, refer to the Low Level Measurements handbook, which is available from Keithley Instruments. Noise Noise generated by source resistance and source capacitance. Accuracy for each measurement function and range is listed in the specifica- tions However, the instrument should be turned on and allowed to warm up for at least one hour before use to achieve rated accuracy. If the instrument has been exposed to extreme temperatures, allow extra time for the internal temperature to stabilize.
Readings can now be taken from the display. For the Model , the MON annunciator indicates that the displayed reading is zero corrected.
Exceeding this voltage may cause damage to the instrument. The maximum input voltage and current to Model is V peak and 21mA. Exceeding either of these values may cause damage to the instrument that is not covered by the warranty. Disable zero check and take a reading from the display If the readings are noisy, you may want to use filtering to reduce noise. Filtering is cov- ered in The can make relative readings with respect to a baseline value or display the logarithm of the absolute value of the measured current.
The can calculate resistance by dividing an externally sourced voltage value by the measured current. View Cart My Account The low voltage burden makes the function much more like an ideal ammeter than a DMM, so it can make current measurements with high accuracy, even in circuits with very low source voltages Scaled Voltage Analog Output This output allows the to transmit measurement results to devices like DMMs, data acquisition boards, oscilloscopes, or strip chart recorders.
One-Touch Front Panel Design Functions can be configured easily with the push of a button, without complicated function menus. Built-In Trigger Link Interface The Trigger Link interface simplifies synchronizing the with other instruments and voltage sources. REL and LOG Functions The can make relative readings with respect to a baseline value or display the logarithm of the absolute value of the measured current.
