Agilent Technologies 34410A - Measurement Configuration Menus

Features and Functions 2
Front Panel Measurement Configuration Menus
Each measurement function is configured separately, except for W 2W and
W 4W (which are partially inter–dependent), and for Frequency and Period,
(which share a configuration menu). The configuration settings (e.g. range,
null value, etc.) for each measurement function are retained when
switching between functions.
• To enter the configuration menu for any selected measurement function,
press . The menus are context–sensitive; only the options
applicable to the selected function will appear. Descriptions of the
menu selections are listed below, for each of the six groups of primary
measurement functions with configurable options (none for
diode/continuity checks.)
• When digit masking is enabled (see “Digit Masking” on page 43) the
DIGIT MASK submenu will appear before other configuration choices.
• For a detailed description of the configuration choices, see “Advanced
Configuration Options” on page 49.
Configuring DC Voltage and DC Current Measurements
For dc voltage and current measurements, your configuration menu
choices are: INTEGRATION, RANGE, AUTO ZERO, NULL and NULL VALUE. For dc
voltage measurements, you can also configure INPUT Z.
• INTEGRATION: Allows you to set the integration time for the measurement
in two ways; in power–line cycles (select NPLC) or in seconds (select
APERTURE).
• RANGE: Allows you to select a fixed range using manual ranging (select
MANUAL), or let the multimeter automatically select the range using the
autoranging feature (select AUTO).
• INPUT IMPEDANCE: Allows you to select a dc input impedance of 10 MW
(select 10MW) or >10 GW (select HI–Z) for the 100 mVDC, 1 VDC and 10
VDC ranges only.
• AUTO ZERO: Allows you to enable for all readings (select ON), enable for
one reading (select ONCE), or disable (select OFF) the auto zero feature,
which subtracts a subsequent zero reading from each measurement
taken, to prevent offset voltages in the multimeter’s input circuitry from
affecting measurement accuracy.
• NULL: Allows you to enable (select ON) or disable (select OFF) the null
measurement feature, which measures the difference between a stored
null value and the input signal.
• NULL VALUE: Allows you to view and edit the null value.
