Safety and Regulatory Information

Measuring Current with A Current Transformer

If a current transformer is used for measuring current, you must use a current transformer with internal secondary protection. Using a current transformer without protection may result in a hazardous voltage resulting in a severe shock or death. In addition, this may cause damage to the instrument.

Crest Factor

Exceeding the crest factor limit may result in an inaccurate or lower reading display. Do not exceed the crest factor limit to avoid instrument damage and risk of electric shock. The crest factor limit is listed in the product data sheet at www.keysight.com/find/truevolt-doc.

Measurement Limits

To avoid instrument damage and the risk of electric shock, do not exceed any of the Measurement Limits defined in the following section.

This product complies with EN/IEC 61326-2-1, for sensitive test and measurement equipment:

When subjected to transient radiated and/or conducted electromagnetic phenomena, the product may have temporary loss of function or performance which is self-recovering. Recovery may take longer than 10 seconds.

When subjected to continuously present electromagnetic phenomena, some degradation of performance may occur.

Unless otherwise noted in the specifications, this instrument or system is intended for indoor use in an installation category II, pollution degree 2 environment per IEC 61010-1 and 664 respectively. It is designed to operate at a maximum relative humidity of 5% to 80% at 40 °C or less (non-condensing). This instrument or system is designed to operate at altitudes up to 3000 meters, and at temperatures between 0 and 55 °C.

Safety and Regulatory Information

For the 34461A, 34465A, and 34470A, the Front/Rear switch selects the terminal set to be used. DO NOT operate this switch while signals are present on the front or rear terminals.

The user-replaceable 3 A current-protection fuse is on the rear panel. There are 3 A and 10 A (34461A, 34465A and 34470A) current-protection fuses located inside the unit. Contact your Keysight Sales and Service Center or refer to product service documentation for replacement instructions.

To maintain protection, replace fuses only with fuses of the specified type and rating.

Input Terminal Measurement Limits

Measurement Limits are defined for the input terminals:

Main Input (HI and LO) Terminals. The HI and LO input terminals are used for voltage, resistance, fre-

quency (period), capacitance, and diode test measurements. Two Measurement Limits are defined for these terminals:

l

HI to LO Measurement Limit. The Measurement Limit from HI to LO (Input terminals) is 1000 VDC or

750 VAC, which is also the maximum voltage measurement. This limit can also be expressed as 1000 Vpk maximum.

l

LO to Ground Measurement Limit. The LO input terminal can safely "float" a maximum of 500 Vpk

relative to ground, where ground is defined as the Protective Earth Conductor in the AC mains power cord connected to the instrument.

As implied by the above limits, the Measurement Limit for the HI input terminal is a maximum of 1500 Vpk relative to ground when LO is at its maximum of 500 Vpk relative to ground.

Current Input Terminal. The current input ("I") terminal has a Measurement Limit of 3 A or 10 A (DC or

AC) between the "I" terminal (3 A or 10 A) and the LO input terminal. Note that the current input terminals will always be at approximately the same voltage as the LO terminal, unless a current protection fuse is open. The 10 A terminal isnot available on the 34460A.

Sense Terminal Measurement Limits

The HI and LO sense terminals are used for DCV ratio measurements and four-wire resistance and temperature measurements. The Measurement Limit is 200 Vpk for all of the terminal pairings: LO sense to LO input, HI sense to LO input, and HI sense to LO sense.

The 200 Vpk limit on the sense terminals is the Measurement Limit. Operational voltages in resistance measurements are much lower – up to ± 12 V in normal operation.

18

Keysight TruevoltSeries Operating and Service Guide

Safety and Regulatory Information

IEC Measurement Category II

To protect against the danger of electric shock, the Keysight Truevolt Series DMM protects the user from AC mains power overvoltage events. When measuring AC mains, the HI and LO input terminals may be connected to AC mains power up to 300 VAC under Measurement Category II conditions as defined below.

IEC Measurement Category II includes electrical devices connected to AC mains power at an outlet on a branch circuit. Such devices include most small appliances, test equipment, and other devices that plug into a branch outlet or socket. The instrument may be used to make measurements with the HI and LO inputs connected to AC mains power in such devices, or to the branch outlet itself (up to 300 VAC). However, the instrument may not be used with its HI and LO inputs connected to AC mains power in permanently installed electrical devices such asthe main circuit-breaker panel, sub-panel disconnect boxes, or permanently wired motors. Such devicesand circuits are subject to overvoltages that may exceed the instrument’s protection capabilities.

Voltages above 300 VAC may be measured only in circuits that are isolated from AC mains power. However, transient overvoltages are also present on circuits that are isolated from ACmains power. The instrument is designed to safely withstand occasional transient overvoltages up to 1500 Vpk when measuring voltages greater than 300 VAC. Do not use this equipment to measure circuits where transient overvoltages could exceed this level.

Introduction to the Instrument

Remote Interface Configuration

If you have the security option installed on your instrument, the instrument must be unsecured with the security code to perform many of these actions.

The instrument supports remote interface communication over three interfaces: GPIB (optional), USB, and LAN (optional on 34460A). All three are "live" at power up when the instrument ships from the factory.

l

GPIB Interface: Set the instrument's GPIB address and connect to your PC using a GPIB cable.

l

USB Interface: Use the rear-panel USB connector to communicate with your PC. For details, see USB

Settings.

l

LAN Interface: By default, DHCP is on, which may enable communication over LAN. The acronym

DHCP stands for Dynamic Host Configuration Protocol, a protocol for assigning dynamic IP addresses to networked devices. With dynamic addressing, a device can have a different IP address every time it connects to the network.

Connectivity Software

l

The instrument ships with the Keysight Automation-Ready CD. This CDcontains Keysight IO Librar- ies Suite software, which must be installed to enable remote-interface operations. The CDauto-starts and provides information on installing the software. Also includes Keysight Technologies

USB/LAN/GPIB Connectivity Guide, which contains additional information.

GPIB Configuration

Each device on the GPIB (IEEE-488) interface must have a unique whole number address between 0 and

30. The instrument ships with a default address of 10, and the GPIB address is displayed at power-on.

l This setting is non-volatile; it will not be changed by power cycling or *RST or SYSTem:PRESet.

l Your computer’s GPIB interface card addressmust not conflict with any instrument on the interface

bus.

l

Front Panel: Press [Utility] > I/O Config > GPIB Settings. From this menu, you can set the GPIB

address and turn GPIB on or off. After making changes, you must cycle power on the instrument for the change to take effect.

Introduction to the Instrument

LAN Configuration

The following sections describe the primary front panel LAN configuration functions, including SCPI commands where applicable. Some LAN configuration functions can be performed only via SCPI. See SYSTem

Subsystem - I/O Configuration for all LAN configuration commands, and see LAN Configuration Procedure to configure the LAN via the front panel.

Some LAN settings require you to cycle instrument power to activate them. The instrument briefly displays a message when this is the case, so watch the screen closely as you change LAN settings.

Resetting the LAN

You can clear the Web Interface password, turn DHCP on, and restart the LAN at any time:

l

Front Panel:[Utility] > I/O Config > LAN Reset

The message "Performing LAN Reset" is displayed while the LAN is reset.

l

SCPI: LXI:RESet

DHCP On/Off

DHCP (Dynamic Host Configuration Protocol) can automatically assign a dynamic IP addressto a LAN device. This is typically the easiest way to configure the instrument for LAN.

l This setting is non-volatile; it will not be changed by power cycling or *RST or SYSTem:PRESet.

l

Front Panel:[Utility] > I/O Config > LAN Settings > Modify Settings

Then set the first softkey to DHCP to use DHCP to automatically assign an IP address.

l

SCPI: SYSTem:COMMunicate:LAN:DHCP {ON|1|OFF|0}

l

If you change this parameter, you must either press the Apply Changes softkey (front panel) or send

SYSTem:COMMunicate:LAN:UPDate (remote interface) for the change to take effect.

To manually set an IP address, Subnet Mask, or Default Gateway, turn DHCP off, then change the IP setup as described below.

Introduction to the Instrument

LAN Configuration Procedure

There are several parameters that you might need to set to establish network communication using the LAN interface. Primarily, you will need to establish an IP address. You might need to contact your network administrator for help in establishing communication with the LAN interface.

If your instrument has the secure (SEC) option, the instrument must be unsecured to change most LAN settings.

1. Press [Utility] > I/O Config > LAN Settings.

2. You can select Modify Settings to change the LAN settings, or you can turn LAN Services on and off

or restore the LAN settings to default values.

3. To change settings, press Modify Settings. To access most items on this screen, use the first softkey

to switch from DHCP to Manual. With DHCP on, an IP address will automatically be set by DHCP (Dynamic Host Configuration Protocol) when you connect the instrument to the network, provided the DHCP server isfound and is able to do so. DHCP also automatically deals with the subnet mask, gateway address, DNS, WINS, and domain name, if required. This is typically the easiest way to establish LAN communication for your instrument; all you need to do is leave DHCP on. Contact your LAN administrator for details.

4. Establish an "IP Setup."

If you are not using DHCP (the first softkey is set to Manual), you must establish an IP setup, including an IP address, and possibly a subnet mask and gateway address. The IP Address and Subnet Mask buttons are on the main screen, and you press More to configure the Gateway.

Contact your network administrator for the IP address, subnet mask, and gateway to use. All IP addresses take the dot-notation form "nnn.nnn.nnn.nnn" where "nnn" in each case is a byte value in the range 0 through 255. You can enter a newIP address using the front panel arrow keys. Do not

enter leading zeros.

32

Keysight TruevoltSeries Operating and Service Guide

Introduction to the Instrument

5. Configure the "DNS Setup" (optional)

DNS (Domain Name Service) is an Internet service that translates domain names into IP addresses. Ask your network administrator whether DNS is in use, and if it is, for the host name, domain name, and DNS server address to use.

a. Set the "hostname." Press Host Name and enter the hostname. A hostname isthe host portion of

the domain name, which is translated into an IP address. The hostname is entered as a string using the front panel arrow keys to select and change characters. The hostname may include letters, numbers, and dashes ("-").

b. Set the "DNS Server" addresses. From the LAN configuration screen, press More to go to the

second of three sets of softkeys.

Enter the Primary DNS and Second DNS. See your network administrator for details.

More about IP Addresses and Dot Notation

Dot-notation addresses ("nnn.nnn.nnn.nnn" where "nnn" is a byte value from 0 to 255) must be expressed with care, as most PC web software interprets byte values with leading zeros as octal (base 8) numbers. For example, "192.168.020.011" is actually equivalent to decimal "192.168.16.9" because ".020" is interpreted as "16" expressed in octal, and ".011" as "9". To avoid confusion, use only decimal values from 0 to 255, with no leading zeros.

Product Grounding

The instrument is a Class 1 product and is provided with a grounding-type power cord set. The instrument chassis and cover are connected to the instrument electrical ground to minimize shock hazard. The ground pin of the cord set plug must be firmly connected to the electrical ground (safety ground) terminal at the power outlet. Any interruption of the protective earth (grounding) conductor or disconnection of the protective earth terminal will cause a potential shock hazard that could result in personal injury or death.

Connect Power and I/O Cables

Connect the power cord and LAN, GPIB, or USB cable as desired. After you turn on the instrument (as described below), the instrument will run a power-on self test and then display a message about how to obtain help, along with the current IP address. It also displays the GPIB address (if applicable).

The instrument's default measurement function isDC Voltage (DCV), with autoranging enabled.

Power Switch

Pressthe power switch in the lower left corner of the front panel. If the instrument does not turn on, verify that the power cord is firmly connected and that the fuse is good and the line voltage selector is set correctly, as described above. Also make sure that the instrument is connected to an energized power source. If the LED below the power switch is off, there is no AC mains power connected. If the LED is amber, the instrument isin standby mode with AC mains power connected, and if it is green, the instrument is on.

In certain circumstances, the amber LED can come on even if the wrong line voltage is selected. In this case, the instrument may not power on.

If the power-on self test fails, the display shows Error in the upper right corner. It also displays a message describing the error. See SCPI Error Messagesfor information on error codes. See Service and Repair -

Features and Functions

Continuous, Data Log, and Digitize Modes

The 34465A/70A can operate in the continuous, data log, or digitize mode as described below.

The 34460A/61A DMMs always operate in the continuous mode -data log and digitize modes

are not available on these models.

Continuous Mode

Continuous mode is the default mode for all Truevolt DMMs. With the factory default settings, the DMM continuously makes DCV measurements with autorange and autozero on, NPLC set to 10 PLCs, etc. (see factory defaults for details).

Data Log Mode

The Data Log mode is standard on the 34465A and 34470A only, as is available only from the DMM's front panel. Data Log mode provides a front–panel user interface that allows you to set up data logging into the instrument’s non–volatile memory, or to internal/external file(s), without programming, and without a connection to a computer. Once you have finished collecting data, you can view it from the front panel, or you can transfer the data to your computer. Data Log mode allows you to log a specified number of readings, or readings acquired for a specified period of time, to instrument memory or to internal or external data files.

To select Data Log mode, press [Acquire] Acquire > Data Log. You can then select the Sample Interval (time between measurements - for example, 500 ms), Duration as either an amount of Time or a number of Readings, whether to Start after a Delay or at a specific Time of Day, and whether to Log to Memory or Log to File(s). After configuring the data logging parameters, press [Run/Stop]. Data logging will begin fol- lowing the specified Delay or at the specified Time of Day.

Digitize Mode

The digitize mode applies only to the 34465A/70A with the DIG option, and asis available only from the DMM's front panel. The digitized mode provides a front–panel user interface that allows you to quickly set up digitized measurements.

Digitizing is the processof converting a continuous analog signal, such as a sine wave, into a series of discrete samples (readings). The figure below shows the result of digitizing a sine wave. This chapter discusses the various ways to digitize signals. The importance of the sampling rate, and how to use level triggering.
