Safety precautions

The following safety precautions should be observed before using this product and any associated instrumentation. Although some instruments and accessories would normally be used with nonhazardous voltages, there are situations where hazardous conditions may be present.

This product is intended for use by personnel who recognize shock hazards and are familiar with the safety precautions required to avoid possible injury. Read and follow all installation, operation, and maintenance information carefully before using the product. Refer to the user documentation for complete product specifications.

If the product is used in a manner not specified, the protection provided by the product warranty may be impaired.

The types of product users are:

Responsible body is the individual or group responsible for the use and maintenance of equipment, for ensuring that the equipment is operated within its specifications and operating limits, and for ensuring that operators are adequately trained.

Operators use the product for its intended function. They must be trained in electrical safety procedures and proper use of the instrument. They must be protected from electric shock and contact with hazardous live circuits.

Maintenance personnel perform routine procedures on the product to keep it operating properly, for example, setting the line voltage or replacing consumable materials. Maintenance procedures are described in the user documentation. The procedures explicitly state if the operator may perform them. Otherwise, they should be performed only by service personnel.

Service personnel are trained to work on live circuits, perform safe installations, and repair products. Only properly trained service personnel may perform installation and service procedures.

Keithley products are designed for use with electrical signals that are measurement, control, and data I/O connections, with low transient overvoltages, and must not be directly connected to mains voltage or to voltage sources with high transient overvoltages. Measurement Category II (as referenced in IEC 60664) connections require protection for high transient overvoltages often associated with local AC mains connections. Certain Keithley measuring instruments may be connected to mains. These instruments will be marked as category II or higher.

Unless explicitly allowed in the specifications, operating manual, and instrument labels, do not connect any instrument to mains.

Exercise extreme caution when a shock hazard is present. Lethal voltage may be present on cable connector jacks or test fixtures. The American National Standards Institute (ANSI) states that a shock hazard exists when voltage levels greater than 30 V RMS, 42.4 V peak, or 60 VDC are present. A good safety practice is to expect that hazardous voltage is present in any unknown circuit before measuring.

Operators of this product must be protected from electric shock at all times. The responsible body must ensure that operators are prevented access and/or insulated from every connection point. In some cases, connections must be exposed to potential human contact. Product operators 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 V, no conductive part of the circuit may be exposed.

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.

Before operating an instrument, ensure that 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.

When installing equipment where access to the main power cord is restricted, such as rack mounting, a separate main input power disconnect device must be provided in close proximity to the equipment and within easy reach of the operator.

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.

For safety, instruments and accessories must be used in accordance with the operating instructions. If the instruments or accessories are used in a manner not specified in the operating instructions, the protection provided by the equipment may be impaired.

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

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

Chassis connections must only be used as shield connections for measuring circuits, NOT as protective earth (safety 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 protective earth (safety ground) using the wire recommended in the user documentation.

The symbol on an instrument means caution, risk of hazard. The user must refer to the operating instructions located in the user documentation in all cases where the symbol is marked on the instrument.

The symbol on an instrument means warning, risk of electric shock. Use standard safety precautions to avoid personal contact with these voltages.

The symbol on an instrument shows that the surface may be hot. Avoid personal contact to prevent burns.

The symbol indicates a connection terminal to the equipment frame.

If this symbol is on a product, it indicates that mercury is present in the display lamp. Please note that the lamp must be properly disposed of according to federal, state, and local laws.

The WARNING heading in the user documentation explains hazards that might result in personal injury or death. Always read the associated information very carefully before performing the indicated procedure.

The CAUTION heading in the user documentation explains hazards that could damage the instrument. Such damage may invalidate the warranty.

The CAUTION heading with the symbol in the user documentation explains hazards that could result in moderate or minor injury or damage the instrument. Always read the associated information very carefully before performing the indicated procedure. Damage to the instrument 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. Standard fuses with applicable national safety approvals may be used if the rating and type are the same. The detachable mains power cord provided with the instrument may only be replaced with a similarly rated power cord. 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 to maintain accuracy and functionality of the product). If you are unsure about the applicability of a replacement component, call a Keithley office for information.

Unless otherwise noted in product-specific literature, Keithley instruments are designed to operate indoors only, in the following environment: Altitude at or below 2,000 m (6,562 ft); temperature 0 °C to 50 °C (32 °F to 122 °F); and pollution degree 1 or 2.

To clean an instrument, use a cloth dampened with deionized water 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., a 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.

Calibration verification limits

The calibration verification limits stated in this section have been calculated using only the DAQ6510 one-year accuracy specifications and ambient temperature ±5 °C from T the instrument was calibrated). They do not include test equipment uncertainty. If a particular measurement falls outside the allowable range, recalculate new limits based on both the DAQ6510 specifications and corresponding test equipment specifications.

Specifications and characteristics are subject to change without notice; please refer to

tek.com/keithley

Example reading limit calculation

Assume you are testing the 10 V dc range using a 10 V input value. Using the DAQ6510 one-year accuracy specification for 10 V dc of ± (25 ppm of reading + 5 ppm of range), the calculated limits are:

• Reading limits = 10 V ± [(10 V × 25 ppm) + (10 V × 5 ppm)]

for the most recent specifications.

(the temperature at which

CAL

• Reading limits = 10 V ± (0.00025 + 0.00005) V

• Reading limits = 10 V ± 0.00030 V

• Reading limits = 9.99970 V to 10.00030 V

Calculating resistance reading limits

Resistance reading limits must be recalculated based on the actual calibration resistance values supplied by the equipment manufacturer. Calculations are performed in the same manner as shown in the preceding example. Use the actual calibration resistance values instead of the nominal values in the example when performing your calculations.

For example, assume that you are testing the 10 kΩ range using an actual 10.03 kΩ calibration resistance value. Using DAQ6510 one-year 10 kΩ range accuracy of ± (75 ppm of reading + 6 ppm of range), the calculated reading limits are:

• Reading limits = 10.03 kΩ ± [(10.03 kΩ x 75 ppm) + (10 kΩ x 6 ppm)]

• Reading limits = 10.03 kΩ ± [(0.7523) + (0.06)] Ω

• Reading limits = 10.03 kΩ ± 0.8123 Ω

• Reading limits = 10.029188 kΩ to 10.030812 kΩ

To verify thermocouple accuracy, you will:

• Apply accurate voltages from the calibrator to the terminals on the front panel of the DAQ6510.

• Verify that the displayed readings are within specified limits.

Thermocouple accuracy is verified by using a dc voltage calibrator to output values from standard thermocouple tables available from the National Institute of Standards and Technology (NIST) or other sources.

In the table following the steps below, three representative values are listed from a type J thermocouple table for temperatures –190 °C, 0 °C, and 750 °C, with their respective thermocouple voltages listed in the “Uncompensated calibrator source value” column. The calibrator source values are based on NIST Monograph 175, reference data 60, version 2.0.

Verify thermocouple accuracy

Because the cable connecting the calibrator to the DAQ6510 can have non-trivial thermal offset voltages, you must first correct for these to verify the DAQ6510 specifications.

DC current verification

The DAQ6510 dc current ranges can be verified using several methods, depending on the level of measurement uncertainty required. This manual describes the verification procedure using a Fluke 8508A or 8588A reference digital multimeter (DMM) in series with the DAQ6510 to determine the nominal test current value for the 10 µA to 100 mA ranges. For the 1 A to 10 A ranges, this manual describes using direct output from a Fluke Model 5720A or 5725A calibrator.

These configurations are adequate for most purposes, but may not provide sufficient test uncertainty

io (TUR) for some users. You must evaluate the measurement uncertainties and ensure that they

rat are adequate for your use.

DC current 10 µA to 100 mA range verification

When verifying dc current on the 10 µA to 100 mA ranges, systematic calibrator and cable offsets must be compensated and test limits calculated based on reference digital multimeter (DMM) readings.

In the following section, offset measurements may exceed DAQ6510 zero-current measurement specifications due to systematic source offset current from the test setup.

To verify the DAQ6510 specifications with zero input current, disconnect all cables and calibrators

om the DAQ6510 input. This is a separate setup from that used in the procedure below for

fr mid-scale and full-scale readings.

8. Note the offset-compensated reference DMM reading, and calculate limits based on DAQ6510 specifications (use the reference DMM reading as the expected value and verify the DAQ6510 accuracy from the calculated reference DMM current).

Test limit calculation for 10 µA to 100 mA ranges

The following tables list nominal test current for 10 µA to 100 mA ranges. Test limits must be calculated relative to actual current, as determined by the reference digital multimeter (DMM) measurement. For example, using a specification of 60 ppm of reading + 9 ppm of range on the 10 mA range, the reference DMM measures 5.00012 mA on the nominal 5 mA test.

Specification tolerance = 5.00012 (mA) × 60 ppm + 10 (mA) × 9 ppm = 0.000390072 mA

Lower test limit = 5.00012 – 0.000390072 = 4.999729928 mA

Upper test limit = 5.00012 + 0.000390072 = 5.000510072 mA

Although the specification tolerance calculated above from the actual test current differs slightly from the values listed in the table (based on nominal value), this difference is generally much smaller than the measurement uncertainty and can be ignored. As a result, the test limits can be calculated from the table specification tolerance as:

Lower test limit = 5.00012 – 0.00039 = 4.99973 mA

Upper test limit = 5.00012 + 0.00039 = 5.00051 mA

9. Repeat steps 1 through 8 for all ranges (10 µA through 100 mA).

AC current verification

The following topics describe how to verify ac current.

Verify ac current on the 100 µA to 3 A ranges

To verify ac current accuracy, you will:

• Apply accurate voltages from the Fluke 5720A or 5730A multifunction calibrator to the DAQ6510

front-panel terminals.

• Verify that the displayed readings fall within specified limits.

Use the values in the following tables to verify the performance of the DAQ6510. Actual values depend on the published specifications (see Example reading limit calculation (on page 2-4

)).

To verify ac current accuracy:

1. On the DAQ6510, press the FUNCTION key and select AC Current.

2. Press the HOME key.

3. Set the range you are verifying.

4. Press the MENU key.

5. Under Measure, select Settings.

6. Make sure that Detector Bandwidth is set to 30 Hz.

AC current is specified for the detector bandwidth setting of 3 Hz. 3 Hz measures accurately for input

signals from 3 Hz to 10 kHz, with reading rates of ≈ 0.5 readings/s. To improve verification throughput to ≈ 3.3 readings/s, set detector bandwidth to 30 Hz for frequencies of 30 Hz to 10 kHz. To verify frequencies 1 kHz and higher, set the detector bandwidth to 300 Hz for faster ≈ 55

readings/s throughput.

Environmental conditions

To make sure you get accurate results, the environment must meet the following conditions.

Temperature and relative humidity

Conduct the adjustment procedures in a test environment with:

• A stable ambient temperature controlled to vary less than ±1 °C during the period of adjustment.

• Keithley Instruments recommends a calibration adjustment temperature (T

different nominal temperature is used, it should be noted on the calibration report. A relative humidity of less than or equal to 40 percent, unless otherwise noted.

• No direct airflow on the input terminals.

Line power

The DAQ6510 requires a line voltage of 100 V to 240 V and a line frequency of 400 Hz, 50 Hz or 60 Hz.

Adjustment overview

DAQ6510 adjustment is performed using a remote connection through either an optional GPIB, LAN, or USB interface. The calibration adjustment commands provided in this manual use the Test Script

Processor (TSP

You can use the Keithley Test Script Builder to send you adjustment commands. See "Test Script Builder (TSB)" in the Model DAQ6510 Reference Manual (DAQ6510-901-01).

) command language. There is no front-panel method for full adjustment.

To use GPIB with your DAQ6510, you must use the KTTI-G Accessory.

Recommended test equipment

The following table summarizes the recommended calibration equipment. Specified accuracy of all functions and ranges is dependent on the precision of reference signals used during the adjustment process. To achieve specified performance, adjustment reference uncertainties must be at least four times smaller than the best corresponding DAQ6510 one-year accuracy specification for measuring that signal.

Calibration and Adjustment Manual

3: Adjustment DAQ6510 Data Acquisition and Multimeter System

General adjustment considerations

• DAQ6510 dc voltage performance is sensitive to errors from thermoelectric potentials generated

by test cables and connections. Be sure to use high-quality cables and connection techniques. When changing a connection during the adjustment process, be sure to allow time (up to five minutes) for thermal settling. Also allow thermal settling time, typically 60 seconds, when changing the TERMINALS FRONT/REAR switch position during adjustment.

• Calibration steps are performed on both rear and front inputs as described in sections below. Be

sure that the TERMINALS FRONT/REAR switch is in the proper position before sending adjustment commands.

• The Keithley Models 8610 and 8620 4-wire shorts connect all four terminals electrically, but the

layout of the board traces makes DAQ6510 adjustment sensitive to their orientation. Note the HI/LO terminal markings and be sure to insert connections in the correct orientation. Note that the DAQ6510 rear input terminals are rotated 90° compared to front-panel inputs.

• During adjustment steps using a calibrator reference source, be sure the calibrator reference

signal has fully settled before sending adjustment commands to the DAQ6510.

The maximum input voltage between INPUT HI and INPUT LO is 1000 V dc and 750 V ac. Exceeding this value may create a shock hazard.

The maximum common-mode voltage (the voltage between INPUT LO and chassis ground) is 500 V

. Exceeding this value may cause a breakdown in insulation that can create a shock

PEAK

hazard.

Some of these procedures may expose you to hazardous voltages, that if contacted, could cau

se personal injury or death. Use appropriate safety precautions when working with

hazardous voltages.

Data Acquisition and Multimeter System Calibration and Adjustment Manual Section 3:

Initial instrument setup

Before adjusting calibration, make sure that the instrument is set up:

• For remote operation and TSP commands.

• To the correct date and time.

You must also unlock calibration.

Select the correct terminals

On the DAQ6510, you must adjust calibration from both the front and rear terminals. You can verify calibration on either the front or rear terminals. To set the instrument to the rear-panel terminals, press the TERMINALS switch on the front panel of the instrument.

Select the TSP command set

Calibration adjustment must be performed by remote control using LAN, USB, or optional GPIB interfaces. No front-panel calibration commands are available.

Calibration is only available using TSP commands. See the instructions below to change the command set.

To set the command set from the front panel:

1. Press the MENU key.

2. Under System, select Settings.

3. For Command Set, select TSP.

4. You are prompted to reboot.

Verify instrument date and time

Before adjusting calibration, verify the system date of the DAQ6510.

From the front panel:

1. Press the MENU key.

2. Under System, select Settings. The SYSTEM SETTINGS menu opens.

3. Verify the date and time.

4. If necessary, correct the date and time.

Set up remote connections

For detail on remote communications, refer to the DAQ6510 Reference Manual section "Remote communications interfaces."

Calibration adjustment is performed by connecting reference signals to the DAQ6510 and sending a series of adjustment commands using one of the remote interfaces. The adjustment procedure may be done interactively, programmatically, or using a combination of the two.

• Interactive: Manually set up and connect each reference signal, then send the appropriate

calibration adjustment command.

• Programmatic: A computer performs setup of calibrator source instruments and controls

appropriate settling delays before automatically sending calibration adjustment commands to the DAQ6510. The control program must determine when the adjustment step is complete and check for adjustment errors before continuing to the next step.

The following section describes the DAQ6510 adjustment commands that are used for a manual interactive adjustment procedure. Techniques for controlling automated program timing and error checking are described in Adjustment command timing and error checking (on page 3-40

Unlock calibration

To start making adjustments, you must unlock it by sending the calibration password:

cal.unlock("KI000CAL")

KI000CAL is the default password. You can change the password. Refer to cal.password (on page

Adjustment

Data Acquisition and Multimeter System Calibration and Adjustment Manual Section 3:

Save calibration and set the adjustment dates

Use the following commands to save and lock calibration adjustments. These steps will take seconds to complete.

cal.save() cal.lock()

Calibration is temporary until you send the cal.save() command. Also, calibration data is not

saved if calibration is locked or if invalid data exists.

This completes the remote calibration adjustment procedure.

Setting time, adjustment, and verification dates

The DAQ6510 calibration adjustment date variable is set automatically to the present system time when the cal.save() command is executed. However, you can also use Test Script Processor

) commands to set the time, verification date, and adjustment date.

(TSP

To set the DAQ6510 time, adjust date, and verify date using TSP commands:

-- Unlock calibration (if not already unlocked). cal.unlock("KI000CAL")

-- Set the time (year, month, date, hour, minutes, seconds). localnode.settime(2018, 1, 9, 10, 4, 38)

-- Set the adjustment and verification dates. cal.adjust.date = os.time({year = 2018, month = 1, day = 9}) cal.verify.date = os.time({year = 2018, month = 1, day = 9})

The cal.verify.date command is used to record the date of the last verification that was done

independently of DAQ6510 adjustment. Typically, this date is set at the completion of a performance verification procedure.

Calibration must be unlocked to change the adjustment and verification dates, but changing these dates does not require using the cal.save() command and does not affect the cal.count

command.

Calibration and Adjustment Manual

3: Adjustment DAQ6510 Data Acquisition and Multimeter System

Adjustment command timing and error checking

Before each adjustment step, the input of the DAQ6510 must be connected to an appropriate reference signal, as documented in Remote calibration adjustment procedures (on page 3-7

You must make sure that the correct signal is connected and fully settled before sending the associated cal.adjust command. Failing to wait for a signal to settle completely may result in a

poor-quality adjustment that could cause the DAQ6510 to fail later performance verification.

Once the reference signal is stable, sending the calibration adjustment command initiates internal measurement operations in the DAQ6510. These steps can take from a few seconds to 30 seconds to complete.

Another method of getting calibration status feedback is to use the TSP prompts mode of operation. This is especially useful when you are entering cal.adjust commands interactively from an

ethernet Telnet session.

To enable prompts mode, send the localnode.prompts = 1 command. This causes the

DAQ6510 to return a TSP> prompt to the computer screen when it has completed a step and is ready

for the next command. Prompts mode also returns a TSP? prompt if an event message is available

(for example, if an error occurs during an adjustment step). See Handling events (on page 3-40 more information.

Although not prohibited, prompts mode is not recommended for automated test programs. If prompts mode is enabled in an automated test, the control program must be constructed to expect and read each prompt that is sent after each TSP command is processed (including queries). Distinguishing prompt messages from normal query responses will cause unnecessary complications to the control program and should be avoided.

Handling events

If an error occurs while performing a calibration adjustment step, the DAQ6510 displays an error message on the front panel. Typically, errors occur during calibration adjustment only if something is wrong with the test setup or reference signal (for example, if the calibrator output is not enabled before sending a cal.adjust command). After correcting the cause, the cal.adjust command

that generated an error can be sent again without having to restart the entire calibration adjustment sequence. An automated test program can check for errors using the eventlog.next() function.

Refer to the DAQ6510 Reference Manual for details on eventlog commands. The same text that is

displayed after a cal.adjust error is returned in the eventlog.next() message.
