Page 14: Chapter 1. Getting Started With The Hp E1326B/E1411B Multimeter
Introduction to Operation......Page 16 Note This manual is to be used with the HP E1326B or HP E1411B installed in the HP 75000 Series B or Series C mainframe, and when the multimeter is programmed using Standard Commands for Programmable Instruments (SCPI) language or when it is programmed at the register level.
Page 15: Functional Description
- digit multimeter can be used stand-alone, or combined with Description multiplexers (for example, HP E1345A/46A/47A/51A/52A/55A/56A/ 57A/58A or HP E1460A/76A) to form a scanning multimeter. In stand-alone operation, input signals are connected to the multimeter’s external (faceplate) terminals. In scanning operation, input signals are connected to the multiplexer channels.
Page 16: Physical Description
An internal installation kit, discussed in Chapter 2, enables you to install the multimeter internal to the HP 75000 Series B mainframe. This saves two externally accessed slots. Input Terminals There are four input terminals on the faceplate of the multimeter (see Figure 2-7 on page 29).
Page 17: Introduction To Operation
Note The HP E1411B has a "Failed" annunciator and an "Access" annunciator on the faceplate. The "Failed" annunciator turns on if the multimeter does not properly respond during the mainframe’s power-on sequence. If this occurs, return the multimeter to Hewlett-Packard for service.
Page 18: Resetting The Multimeter
If self-test code 1, 2, 3, or 4 occurs, return the multimeter to Hewlett-Packard for repair. Note If the multimeter did not respond to the self-test, the address you specified may be incorrect. Refer to Chapter 2 in this manual and the HP VXIbus Systems Installation and Getting Started Guide. Resetting the During operation, programming errors and other conditions may occur making it necessary to reset the multimeter.

Page 22: Chapter 2. Configuring The Hp E1326B/E1411B Multimeter
Installation Overview As mentioned in the HP VXIbus Systems Installation and Getting Started Guide, each plug-in module has a row of switches which set the module’s logical address. Based on this address, the system instrument within the HP 75000 Series B mainframe and HP E1406A command module combines the modules into virtual instruments.
Page 23: Setting The Logical Address Switch
The switch has a factory setting of 24 which is equivalent to a secondary HP-IB address of 03. If you have more than one multimeter, you must change the logical address to some other multiple of 8 (for example, 32, 40, 48...), as there can only be one instrument per secondary address.

IRQ jumper must be set accordingly. Figure 2-3 shows the location of the jumpers used to select an interrupt line. For most applications where the multimeter is installed in an HP 75000 Series B or Series C mainframe, the jumpers do not have to be moved.
Page 26: Hp E1326B Internal Installation
This prevents another module from being installed in the slot directly above the multimeter. To make the two slots available to other modules, the HP E1326B can be installed internal to the mainframe (in slot 2) using an internal installation kit (HP P/N E1326-80004).
Page 27: Installing The Hp E1411B In A Mainframe
Installing the The HP E1411B multimeter can be installed in any slot (except slot 0) in a C-size VXIbus mainframe. Refer to Figure 2-5 to install the E1411B in a HP E1411B in a mainframe. Mainframe Set the extraction levers out.
Page 28: The Reference Frequency
Frequency type of noise emanates from the surrounding environment, primarily from 50 Hz and 60 Hz power lines. The HP E1326B/E1411B multimeter is able to reject normal mode noise by using an integrating analog-to-digital (A/D) converter. The integration process averages out the power line related noise over an integer number of power line cycles (PLCs) during the A/D conversion.

However, to specify a resolution while autoranging, must be explicitly specified. This prevents the AUTO resolution from being interpreted as a range setting.

Page 95: Autorange
If autoranging is enabled but does not occur, approximately 100 µs is added to the fixed range measurement time. The E1326B/E1411B automatically switches to the 10 µs aperture time when making measurements to determine the correct range. 2. For maximum speed, group channels together which use the same range.

See Chapter 5 for additional information. Triggering the Multimeter The E1326B/E1411B multimeter operates in an idle state, a wait-for-trigger state, and a triggered state. Configuration of the multimeter and its trigger system occurs while the multimeter is in the idle state. When the multimeter is ready to make a measurement, it is placed in the wait-for-trigger state.

Page 270: Appendix D. Measurement Speed And Accuracy Tradeoffs
Appendix D Measurement Speed and Accuracy Tradeoffs The HP E1326B SCPI driver was designed so that its default mode of operation will deliver high accuracy readings with a minimum of programming effort. However, many applications require high-speed measurements and reduced reading accuracy is acceptable.
Page 271 Avoid Function The E1326B multimeter (DMM) takes time to switch between its various Changes functions because the hardware is reconfigured and calibration constants for the new function are retrieved. Organize your program so all measurements on a function are done at the same time. This is best accomplished with a scan list.
Page 272 ASCII, and then the computer must convert the ASCII number to its internal format which is either 32- or 64-bit REAL. A REAL number in HP BASIC is a 64-bit REAL. In the C language, variable type "float" is a 32-bit REAL number, and variable type "double"...

[SENSe:]RESistance:RANGe:AUTO ON | OFF You can verify the auto range mode by querying the E1326B as to its auto range status using the following commands: [SENSe:]VOLTage:RANGe:AUTO? [SENSe:]VOLTage:AC:RANGe:AUTO? [SENSe:]RESistance:RANGe:AUTO? Decrease Aperture The aperture time is the amount of time that the input signal is integrated.
Page 277 Setting the Resolution The aperture time is set as a result of specifying the < resolution > parameter in the MEASure CONFigure command, or by directly setting it with the VOLTage:APERture RESistance:APERture command. Table 4-5 on page 92 can be used to pick a value for the <...

Page 279 This is the mode of operation that should be used when readings need to be taken at a continuous rate. The controller needs to remove the readings at a rate such that the HP-IB output buffer (128 characters) and the 512 word multimeter Data Register (used when is used) does not overflow.
