greater than 30V RMS, 42.4V peak, or 60VDC are present.

A good safety practice is to expect that hazardous voltage is present in any unknown circuit before measuring.

Users of this product must be protected from electric shock at all times. The responsible body must ensure that users are prevented access and/or insulated from every connection point. In some cases, connections must be exposed to potential human contact. Product users in these circumstances must be trained to protect themselves from the risk of electric shock. If the circuit is capable of operating at or above 1000 volts,

As described in the International Electrotechnical Commission (IEC) Standard IEC 664, digital multimeter measuring circuits (e.g., Keithley Models 175A, 199, 2000, 2001, 2002, and 2010) are Installation Category II. All other instruments’ signal terminals are Installation Category I and must not be connected to mains.

Do not connect switching cards directly to unlimited power circuits. They are intended to be used with impedance limited sources. NEVER connect switching cards directly to AC mains. When connecting sources to switching cards, install protective devices to limit fault current and voltage to the card.

no conductive part of the circuit may be

Before operating an instrument, make sure the line cord is connected to a properly grounded power receptacle. Inspect the connecting cables, test leads, and jumpers for possible wear, cracks, or breaks before each use.

For maximum safety, do not touch the product, test cables, or any other instruments while power is applied to the circuit under test. ALWAYS remove power from the entire test system and discharge any capacitors before: connecting or disconnecting cables or jumpers, installing or removing switching cards, or making internal changes, such as installing or removing jumpers.

Do not touch any object that could provide a current path to the common side of the circuit under test or power line (earth) ground. Always make measurements with dry hands while standing on a dry, insulated surface capable of withstanding the voltage being measured.

The instrument and accessories must be used in accordance with its speciﬁcations and operating instructions or the safety of the equipment may be impaired.

Do not exceed the maximum signal levels of the instruments and accessories, as deﬁned in the speciﬁcations and operating information, and as shown on the instrument or test ﬁxture panels, or switching card.

When fuses are used in a product, replace with same type and rating for continued protection against ﬁre hazard.

Chassis connections must only be used as shield connections for measuring circuits, NOT as safety earth ground connections.

If you are using a test ﬁxture, keep the lid closed while power is applied to the device under test. Safe operation requires the use of a lid interlock.

If a screw is present, connect it to safety earth ground using the wire recommended in the user documentation.

The symbol on an instrument indicates that the user

should refer to the operating instructions located in the manual.

The symbol on an instrument shows that it can source or measure 1000 volts or more, including the combined effect of normal and common mode voltages. Use standard safety precautions to avoid personal contact with these voltages.

WARNING

The might result in personal injury or death. Always read the associated information very carefully before performing the indicated procedure.

could damage the instrument. Such damage may invalidate the warranty.

Instrumentation and accessories shall not be connected to humans.

Before performing any maintenance, disconnect the line cord and all test cables.

To maintain protection from electric shock and ﬁre, replacement components in mains circuits, including the power transformer, test leads, and input jacks, must be purchased from Keithley Instruments. Standard fuses, with applicable national safety approvals, may be used if the rating and type are the same. Other components that are not safety related may be purchased from other suppliers as long as they are equivalent to the original component. (Note that selected parts should be purchased only through Keithley Instruments to maintain accuracy and functionality of the product.) If you are unsure about the applicability of a replacement component, call a Keithley Instruments ofﬁce for information.

To clean an instrument, use a damp cloth or mild, water based cleaner. Clean the exterior of the instrument only. Do not apply cleaner directly to the instrument or allow liquids to enter or spill on the instrument. Products that consist of a circuit board with no case or chassis (e.g., data acquisition board for installation into a computer) should never require cleaning if handled according to instructions. If the board becomes contaminated and operation is affected, the board should be returned to the factory for proper cleaning/servicing.

Basic measurement procedure

1. Connect the instrument as explained in “Instrument connections”.

2. From the function keys, select the desired measurement function.

3. Use the RANGE keys to select autoranging or a manual range. Pressing the AUTO range key toggles autoranging. You can select a different range with the ▲ and ▼ RANGE keys.

4. Take a reading from the display.

Storing readings (2 to 1024)

1. Set up the instrument for the desired conﬁguration.

2. Press the STORE key.

3. Use the , , ▲, and ▼ keys to select the number of readings to store in the buffer.

4. Press ENTER to start the storage process. The asterisk (*) annunciator will turn off when the storage is ﬁnished.

Recalling readings

1. Press the RECALL key. The BUFFER annunciator indicates stored readings are being displayed. The arrow annunciator indicates there is more data in the buffer.

2. Use the , , ▲, and ▼ keys to view the buffer. Note that in addition to the readings, statistical data is available including standard deviation, average, minimum, and maximum.

3. Use the EXIT key to return to the normal display.

Changing speed, resolution, and ﬁlter

RATE

— Measurement speed (reading RATE) can be changed for any measurement function except frequency, period, continuity, and diode test. Use the RATE key to select FAST, MEDium, or SLOW. Use FAST (0.1 PLC) if speed is of primary importance (at the expense of increased noise and fewer usable digits of resolution). SLOW (5 PLC) provides better noise performance at the expense of speed. MEDium (1 PLC) provides a compromise between noise and speed. The RATE setting also sets bandwidth for ACU and ACI measurements. See the 2010 User’s Manual for details.

DIGITS

— Display resolution can be changed for any measurement function. Use the DIGITS key to select the desired number of digits.

FILTER

— Filter state (on/off) and conﬁguration can be changed for any measurement function, except frequency, period, continuity, and diode test. The FILTER key toggles between ﬁlter on (FILT annunciator on) and ﬁlter off. After pressing FILTER to enable the ﬁlter, you can then enter the ﬁlter count (1 to 100), and select the ﬁlter type (moving or repeating).

The moving ﬁlter uses a ﬁrst-in, ﬁrst-out (FIFO) stack. After each new conversion is placed in the stack, the contents of the stack are averaged to yield a ﬁltered reading. The repeating ﬁlter ﬁlls the stack, calculates the ﬁltered reading, and then clears the stack for the next group of conversions.

Changing temperature measurement conﬁguration

Press SHIFT and then SENSOR. Three choices are available using the , , ▲, and ▼ keys:

• UNITS – C, K, F. Specify units.

• SENSOR – TCOUPLE or 4W-RTD. Specify sensor

type.

• TYPE – J, K, N, T (thermocouple type) or PT100,

USER, PT3916, PT385, F100, D100 (4W-RTD type).

• JUNC – SIM or CH1. Simulate a reference junction

temperature (for direct thermocouple connection to the input), or use reference junction (channel 1) on the switching card.

Relative (rel)

Rel can be used to null offsets or subtract a baseline reading from present and future readings. When rel is enabled by pressing REL (REL annunciator on), the instrument uses the present readings as the relative value. Subsequent readings will be the difference between the actual input value and the rel value. You can deﬁne a rel value for each function. Pressing REL a second time disables rel.

Math

To enable and conﬁgure a math operation, press SHIFT and then the desired math key (MX+B, %, dBm, or dB). Use the , , ▲, and ▼ keys to conﬁgure the math operation and press ENTER when ﬁnished. Pressing SHIFT and then the related math key a second time disables the math operation.

Measuring continuity

With this feature, the instrument alerts you with a beep when a resistance reading is below the set level. To measure continuity, press SHIFT and then CONT. Use the , , ▲, and ▼ keys to set the resistance threshold level, and press ENTER. Connect the test leads to INPUT HI and LO.

Testing diodes

With this feature, the instrument measures the forward voltage drop of general-purpose diodes and the zener voltage of zener diodes. To test diodes, press SHIFT and then . Use the ▲ and ▼ keys to select the test current.

Limit operations

With this feature, you can check to see if readings are within, below, or above speciﬁed low and high reading limits. There are two sets of limits. The ﬁrst set is LL1 (low limit 1) and HL1 (high limit 1). The second set is LL2 (low limit 2) and HL2 (high limit 2). Typically, the limit 1 test range is used to check for tight tolerances, and the limit 2 test range is used to check for loose tolerances.

You can set the instrument to beep when readings are inside or outside limit ranges. If set to beep inside, a high tone beep will occur if the reading is inside both limit ranges. A lower tone beep will occur if the reading is outside the ﬁrst limit range but inside the second limit range. No beep will occur if the reading is outside both limit ranges.

If set to beep outside, the instrument will beep if the reading is outside the limit 1 range.

Setting limits

LIMITS. Use the , , ▲, and ▼ keys to edit the value for the displayed limit and press ENTER.

Reading hold

With this feature, an audible beep is sounded when a valid, settled reading is acquired. A valid reading is determined by the speciﬁed window and count.

1. Press SHIFT and then HOLD. Select a window percentage and enter a count.

2. Apply the test probes to the signal and wait for the beeper to sound to indicate a valid reading.

3. Remove the hold condition by lifting the probes.

Pressing SHIFT and then HOLD a second time disables hold.

Dry circuit testing

This feature lets you make low resistance measurements on contact devices such as switches and relay contacts. Its purpose is to determine whether oxidation has increased the resistance of the contacts. Test voltage is limited to 20mV to keep the oxidation from being punctured. Punctured oxidation would invalidate the test.

While in 4-wire ohms (Ω4), select dry circuit testing by pressing SHIFT and then DRYCKT.

Offset compensation

Offset compensation is used to cancel the effect of voltage potential (i.e., thermal offsets) across the device under test during resistance measurements. In general, the instrument performs voltage measurements at two different test current levels and then calculates resistance as follows:

R = ∆V / ∆I

While in 2-wire or 4-wire ohms (Ω2 or Ω4), select offset compensation by pressing SHIFT and then O COMP.

Ratio

This feature lets you perform a ratio calculation between the sense input (denominator) and the measure input (numerator) for DC voltage. It lets you compare DC voltages (measure input) to a reference voltage (sense input). Note that SENSE LO and LO should be connected together.

CAUTION Do note apply more than 1000V peak to the measure INPUT terminals or more than 350V peak to the SENSE terminals, or instrument damage may occur.

While in DC volts (DCV), select ratio by pressing SHIFT and then RATIO. Use the , , ▲, and ▼ keys to toggle RATIO to ON and SENSIN to OFF. The display will read RA for ratio.

Measure DCV using SENSE terminals

The sense terminals can be used to measure DC voltage on the 100mV, 1V, and 10V ranges. Note that SENSE LO and LO should be connected together.

CAUTION Do note apply more than 350V peak to the SENSE terminals, or instrument damage may occur.

While in DC volts (DCV), press SHIFT and then RATIO. Use the , , ▲, and ▼ keys to toggle RATIO to OFF and SENSIN to ON. The display will read RS for voltage on SENSE terminals.

Triggers

Factory defaults place the instrument in a continuous (immediate) measurement mode. The instrument can be

placed in an external trigger mode where a programmed event is required to cause a measurement (device action).

The instrument is placed in the external trigger mode by pressing the EX TRIG key. In this mode, a device action (measurement) will occur when the TRIG key is pressed, a bus trigger (*TRG or GET) is received, or an input trigger via the TRIGGER LINK connector is received. After the device action (measurement), an output trigger occurs and is available at the TRIGGER LINK connector. Refer to the Model 2010 User’s Manual for details on using the trigger link. Pressing EX TRIG a second time returns the instrument to continuous operation.

Delay

— A programmable delay is available before the device action (measurement) occurs. It can be set manually or an auto delay can be used. To set a delay, press SHIFT and then DELAY. Use the ▲ and AUTO or MANual. If MANual is chosen, enter the duration of the delay and press ENTER. The AUTO delay times are listed in Table 3-2 of the Model 2010 User’s Manual.

▼ keys to select

Scan operations

The Model 2010 can be used with an internal scanner card (Model 2000 SCAN or 2001-TCSCAN), or with external scanner cards installed in a switching mainframe (i.e., Model 7001 and 7002 or 707).

Step/Scan conﬁguration — A “walk-through” menu is provided to conﬁgure stepping or scanning. The main menu is accessed by pressing SHIFT and then CONFIG.

Use the , , ▲, ▼, and ENTER keys to select scan

type (INTernal or EXTernal), ﬁrst channel in the scan (MINimum CHANnel), last channel in the scan (MAXimum CHANnel), time between scans, and reading count (RDG CNT).

and keys — These keys can be used to manually

scan through channels on the internal scanner card. Press to manually increment channels or to manually decrement channels. Hold down either key to scan continuously.

OPEN and CLOSE keys — Use these keys to open and close channels on the internal scanner card. After press-

ing CLOSE, use the , , ▲, and ▼ keys to display the

desired channel (1 to 10) and press ENTER. Selecting a different channel will cause the previously closed channel to open. For the Ω4 function, CLOSE will close the selected channel and the paired channel. Paired channels for the Model 2000 SCAN are 1&6, 2&7, 3&8, 4&9, and 5&10. Channel pairs are similar for the Model 2001-TCSCAN except channels 1&6 are not paired.

STEP key — Pressing this key starts a stepping operation of consecutive channels, where output triggers are sent after every channel closure.

SCAN key — Pressing this key starts a scanning opera- tion of consecutive channels, where an output trigger is sent at the end of the scan list.

HALT — Pressing SHIFT and then HALT stops stepping or scanning.

Remote Operation Summary

At the factory, the instrument is set for GPIB bus operation at primary address 16 using the SCPI programming language.

GPIB bus — Use the GPIB bus conﬁguration menu to enable or disable GPIB bus operation (ON or OFF), and to check and/or change the primary address (0 to 30) and language (SCPI or 196/199). The conﬁguration menu is accessed by pressing SHIFT and then GPIB. Commands for the SCPI language are provided in Tables 4 through 15. The DDC commands for the 199 and 196 languages are provided in Table 16.

RS-232 interface — Use the RS-232 interface menu to enable or disable RS-232 interface operation (ON or OFF), and to check and/or change the baud rate (300 to

19.2k), ﬂow control (NONE or XonXoFF), and terminator (LF, CR, LFCR, or CRLF). Note that only the SCPI language commands can be used over the RS-232 interface.
