*LCR-816/826/827/829 is one fold less accuracy than LCR-817/819.
(LCR-816/826: 0.1%, LCR-827/829: 0.1%, LCR-817/819/821: 0.05%)
+: Please refer to page 39~43 for details.
Test Frequency:
There are 504 test frequencies between 12Hz and 200kHz that can be selected
by using keypad for LCR-821. The frequency range of LCR-819/829 covers
from 12Hz to 100kHz (total test frequencies: 503 points), LCR-817/827 covers
from 12Hz to 10kHz (total test frequencies: 489 points), LCR-816/826 covers
from 100Hz to 2kHz (total test frequencies: 16 points).
Measurement Displays:
The measured results can be shown on the LCD monitor in three ways:
:1. VALUE
The measured quantities of R/Q, C/D, C/R, L/Q, Z/θ, L/R.
*The resolution of primary display (L, C, R or Z) is to be five
digits.
*The resolution of secondary display (D, Q, R with C, or R with
L) is to be four digits.
*The resolution of secondary display (θ) is to be2 digits after
decimal dot.
2. DELTA %
: The DELTA% shows the percent deviation of the measured L,
C, R or Z value from a saved NOMINAL VALUE. The sign of
deviation is indicated.
:3. DELTA
The LCR difference is similar to the DELTA% except that the
deviation is shown in suitable units (ohms, henries, etc.)

Equivalent Circuit:
The L, C, or R equivalent SERIES or PARALLEL circuit can be selected by
keypad.
* When select Z/θ mode, the PARALLEL circuit is invalid. Please refer to 4-4-
2. Series & Parallel Equivalent Circuit from page 12~13 for details.
Measurement Modes:
Two modes are available: AUTO and MANUAL.
“AUTO” mode is measuring continuously, updating the display after each
measurement.
“MANUAL” mode is activated by the START keypad, the measured result is
holding on the LCD monitor until next measurement started.
Average:
The AVERAGE of any number of measurements from 1 to 255 can be made as
desired in either of the two measurement modes.
Test Voltage:
The test voltage range for LCR-817/819/827/829/821 is from 5mV to 1.275V,
each step is 5mV, for LCR-816/826 is from 0.1V to 1.275V, each step is 5mV.
Note: When the test frequency is at 200kHz, the test voltage must be greater
than 100mV.
Memory:
100 memory blocks totally.
DC Bias:
A 2V internal bias can apply to capacitors during measurement.
Up to 30VDC external bias can apply to capacitors during measurement via the
two terminals (located on the rear panel). The applied current should not over
200mA.
* The external bias specified on the rear panel is at 30VDC, actually, it can be
tolerated to 35VDC.
