*LCR-816/826/827/829/821 is one fold less accuracy than LCR-817/819.
(LCR -816/826: 0.1%, LCR -827/829/821: 0.1%, LCR-817/819: 0.05%)
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: 504 points) , LCR-817/82
7 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/?, L/R.
*The resolution of primary display (L, C, R, 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 (?) is to be
2 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 t
he
deviation is shown in suitable units (ohms, henries, etc.)
