MEASUREMENT

1.1kHz

The nearest frequency will be selected from the
504(LCR-281) nominal frequencies, and
updated in the display. Here, the nearest
frequency to 1.1kHz is 1.0909kHz.

Note

After the test frequency has been changed, the zeroing
must be performed again. See page 24

Set measurement voltage

Background

Along with frequency, voltage can be set. Make
sure the appropriate voltage is selected, according
to the component characteristics.

Range

5mV ~ 1.275V (5mV steps) <200kHz

100mV ~ 1.275 (5mV steps) @200kHz

Voltage setting

1. From the main menu, press MENU (F5)

followed by SETTING (F3) and VOLT (F2)

2. Enter the voltage using the numerical keys, and

then press ENTER.

Manual

The voltage is updated in the display. If the
voltage entered is outside the allowable voltage
range, the nearest voltage is selected.

3. Press (F5) EXIT to exit the Setting

menu.

Set PPM for D/Q measurements

Background

Dissipation and Quality Factor (D/Q)
measurements can be shown in parts per million
(PPM) if D/Q is less than 0.0100. This increases the
resolution by a factor of 100. The units of D and Q
are dimensionless and are expressed as a decimal
ratio with a multiplier of 1,000,000.

Ensure the operating mode has a D or Q component.
See page 33.

Panel operation

1. Press 4/PPM to turn PPM on or off

for all D/Q measurements
