The Model provides automatic selec- tion of 2″terminal or 4-term,mal resistance measurements.
These factory default conditions are listed in Tables and located in Section 3. This instrument will return to normal display mode, and the storing of calibration constants is now enabled.

The machine conditions of the Model will be listed on the CRT display. When an illegal command is received, the instrument will briefly display the following error message: The current LO limit will be displayed. To store a series of readings in the buffer after the ENTER button is pressed, send T6 continuous on ksithley ternal trigger over the bus. In this case, suppress- ing EOI with the K command may cause the controller in- put sequence to hang unless other terminator sequences are used.
The first calibration value should be approximately full range and the second calibration value should be approximately zero. Also included in the schematic are some notes on suitable replacement parts for the original transistors, most of which are no longer available.

Schematics in PDF — Credits to jhzyou The top analog circuit board is encased between two pieces of very thick aluminum shielding, and the bottom piece serves as the mounting plate for the analog board as well. Connect the Model to the desired location in the circuit. The value command may take on either of the following forms: Calibration standard for next units: Some examples of valid command strings include: Depressing and releasing the switch a second time turns the power off.
Determining Q— The Q of a tuned circuit can be deter- mined as follows: Factory Default Conditions At the factory, the Model is set up so that the instru- ment is configured to certain setup conditions on the initial power up. The value can be a calibration value, or a zero value. OLD is a reserved word that prevents the instrument from responding to the defined Translator words.
For exam- ple, if the LO limit is the factory default value, the follow- ing message will be displayed: IDDC To correct the error condition, send only valid commands. Dangerous arcing can also result when the meter is set to a voltage range if the minimum voltage spacing is reduced. The length of time will vary somewhat de- pending on the selected function and trigger mode.
To retain the fac- tory default conditions as power-up default conditions, run Program 30 Save immediately after executing Program 37 Reset.

The U2 command can also be used to list the Translator words see paragraph 3. Unsorted RAW directory — Last update: Two screws are located on each connector to ensure that connections re- main secure. If the displayed frequency setting matches the available line frequency, proceed to step 4. Do not use this application to check amplifiers that exceed the bandwidth of the Model Zero will enable, and the display will zero with the input signal becoming the zero baseline level.
Add additional connectors from other instruments, as required.
This can be demonstrated by touching the cir- manuql, by placing a heat source near the circuit or by a regular pattern of instability corresponding to heating and air-conditioning systems or changes in sunlight. This means that if the ohms sense leads are not connected, the measurement is done 2-terminal. The pictures below are the top analog circuit board and the main board at the bottom, with the shielding and analog board removed:.
Connect the desired baseline level to the input of the Model and note that level on the display. Using Kelvin test leads such as the Keithley Model connect the resistance calibrator to the Model as shown in Figure Attach the test leads to the circuit under test.
Instead, one of the following messages will be displayed: That Translator word will retain its original definition. The B1 command is used to access readings from the burfer. The actual value of the limits is dependent on the range.

Report any damage to the shipping agent. When RMT is turned off, the instrument is in the local mode. The resolution available is dependent on function and range.
Most controllers also use a primary address; consult the controller instruction manual for details. The format for doing this is demonstrated in the following examples: In the B1 mode, the data will come from the buffer. To use the voltmeter complete output, proceed as follows:
