“Changing the auto power-off and backlight time-outs” on page 73

.

• If an external power adapter is used, the backlight time-out will be disabled.


Introduction 1


Selecting the range

Pressing Range

Auto

switches the LCR meter between manual and autoranging. It also cycles through the available LCR meter ranges when manual ranging is enabled.

Autoranging is convenient because the LCR meter automatically selects an appropriate range for sensing and displaying each measurement. However, manual ranging results in better performance, since the LCR meter does not have to determine which range to use for each measurement.

In autorange, the LCR meter selects the lowest range to display the highest available precision (resolution) for the input signal. If manual range is already enabled, press Range

Auto for more than 1 second to enter the autoranging mode.

If autoranging is enabled, press Range

Auto

to enter the manual range mode.

Each additional press of Range

Auto

sets the LCR meter to the next higher range, unless it is already in the highest range, at which point the range switches to the lowest range.

N O T E

Figure 2-1 Using the Ai function

The annunciator will flash while the LCR meter identifies the DUT, and

• selects an appropriate measurement in the primary display (L, C, or R) and secondary display (D, Q, or

θ),

• selects an appropriate range, and

• selects an appropriate measuring mode (series or parallel).

The Ai function helps to identify L, C, and R measurements automatically according to the angle of impedance detected in the DUT. See

Table 2-1 for

the phase angle rules.

The default phase angle condition is set to 10°. You can change this angle in the Setup menu from 5° to 45°. See

Making Measurements

Measuring impedance (Z)

All circuit components, resistors, capacitors, and inductors have parasitic components. These include, for example, unwanted resistance in capacitors, unwanted capacitance in inductors, and unwanted inductance in resistors. Thus, simple components should be modeled as complex impedances.

Set up your LCR meter to measure impedance as shown in

Figure 2- 9

.

more information on how to change the default measurement mode (parallel or series) for subsequent power cycles.



Making Measurements

Setting the standard reference tolerance (Tol%)

The tolerance ranges available are 1%, 5%, 10%, and 20%.

To enable the tolerance mode, insert an appropriate component as a standard value into the component socket or connect the test clip to the component leads, then press the

Tol% key to set this value as the standard reference tolerance.

Similarly, any value which appears on the display, such as

Hold or Max/Min/Avg (Rec), can be used as a standard value to sort components. Press Tol% again to cycle through 1%, 5%,

10%, and 20% tolerance as desired.

This function is designed for convenient component sorting.

The beeper will beep three times whenever the component under test exceeds the setting tolerance. Conversely, when the beeper beeps once, this indicates that the component is within the setting tolerance.

• The tolerance mode cannot be activated if is shown on the display or when the tested capacitance value is below 50 counts.

• Tolerance mode is only available in manual ranging; therefore, activation while in autoranging will automatically set the LCR meter to manual ranging.

Setting the high/low limit comparison (Limit)

The high and low limit comparison function helps you to sort components easily. There are 32 limit sets available (16 fixed factory sets, and 16 variable user sets).

The LCR meter will use the factory sets by default. You can set the LCR meter to use the user sets upon start- up from the Setup menu. See

Making relative measurements (Null)

When making relative measurements, also called null, each reading is the difference between a stored (selected or measured) relative value and the input signal.

One possible application is to increase the accuracy of a resistance measurement by nulling the test lead resistance

(test leads shorted). Nulling the leads is also particularly important prior to making capacitance measurements (test leads open).

Press the Null

Cal

key to enter the relative mode and store the display reading as a reference value. The LCR meter will then display all subsequent readings relative to the reference value.

Null

• Relative mode is only available in manual ranging; therefore, activation while in autoranging will automatically set the LCR meter to manual ranging.

• The relative mode cannot be activated if the LCR meter is set at auto-ranging with data hold activated.

Performing the open/short CAL

The CAL function offsets (corrects) the LCR meter's internal parameters as well as external connector residues for further measuring. Performing this action will help you to correct the influence for temporary uses.

There are three types of open/short CAL available:

• OS- Factory: Open/Short CAL is performed during factory calibration mode (security code protected). It covers all frequencies and all ranges.

• OS- User: Open/Short CAL is performed at every power- on option interval. It covers all frequencies and all ranges.

(see

page 10

for the OS- User setup).

• Open/Short CAL for single range and frequency by pressing and holding the Null

Cal

key for more than 1 second.

The corrections for the and are pre- stored in the LCR meter. They are both calibrated at the terminal ends.

SMD Tweezers Specifications

The Agilent U1782B is a tweezers to be used with the U1700

Series Handheld LCR Meters. This tweezers is useful when measuring SMD- type components. Plug in the base of the tweezers to the LCR meter's + (HI- SENSE), – (LO- SENSE) and GUARD ends. Ensure that the orientation of the base matches the polarity of the LCR meter.

It is recommended to measure the SMD components length as well as the maximum opening of the tweezers. The length of the tweezers is approximately 815 mm (32.08 inches) (see

Figure 4- 1

).
