BASIC MEASUREMENT
35
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

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.
