What are the Quick Setup options?
The QUICKSET key opens a screen that provides access to function selection, performance
adjustments, and quick setups.
The Function button on the Quickset menu allows you to select a source or measure function. The
options are the same as those available when you use the front-panel FUNCTION key.
The Performance slider allows you to adjust speed and resolution. As you increase speed, you lower
the amount of resolution. As you increase resolution, you decrease the reading speed. These settings
take effect the next time the output is turned on and measurements are made.
The Quick Setups allow you to set the instrument to operate as a Voltmeter, Ammeter, Ohmmeter, or
Power Supply.
When you select a Quick Setup, the instrument turns the output on. Carefully consider and
configure the appropriate output-off state, source, and limits before connecting the 2470 to a
device that can deliver energy, such as other voltage sources, batteries, capacitors, or solar
cells. Configure the settings that are recommended for the instrument before making
connections to the device. Failure to consider the output-off state, source, and limits may
result in damage to the instrument or to the device under test (DUT).
What is the output-off state?
When the source of the instrument is turned off, it may not completely isolate the instrument from the
external circuit. You can use the output-off setting to place the 2470 in a known, noninteractive state
during idle periods, such as when changing the device under test. The appropriate output-off state
depends on your system and the device under test. Different types of connected devices or loads
require different behaviors from the 2470 when the output is turned off. For example, a passive
device such as a diode is not affected by a 0 V source connected across its terminals when the
output is turned off. However, connecting a 0 V source to the terminals of a battery causes the battery
to discharge.
The output-off states that can be selected for a 2470 are normal, high-impedance, zero, or guard.
Carefully consider and configure the appropriate output-off state, source, and source limits
before connecting the 2470 to a device that can deliver energy, such as other voltage
sources, batteries, capacitors, or solar cells. Configure recommended instrument settings
before making connections to the device. Failure to consider the output-off state, source, and
source limits may result in damage to the instrument or to the device under test (DUT).
