BASIC MEASUREMENT

Panel operation

1. Press the 7/Bias key on the number

pad to cycle from internal to

external bias. The bottom of the

screen will display internal or

external bias.

2. Press 8/ON/OFF to turn the bias

voltage on or off. The bottom of the

screen will display the internal or

external bias as on or off.

Set measurement frequency

Background

The measurement frequency, together with the

measurement voltage is used to define the

electrical characteristics of each measurement item.

Make sure the appropriate frequency is selected

according to the component characteristics.

The frequency range of each model is as follows:

100Hz~2kHz LCR-816/826

12Hz~10kHz LCR-817/827

12Hz~100kHz LCR-819/829

12Hz~200kHz LCR-821

LCR-800 User Manual

The LCR-821 can provide 504 different frequencies

with a 5 digit resolution including decimal places.

Any frequency can be keyed from the number pad,

and the closest available frequency (of 504) will be

selected automatically. The LCR-818/829 has 503

different frequencies and the LCR-817/827 and

LCR-816/826 have 489 and 245, respectively.

To calculate the different possible frequencies, use

the tables below.
