CAUTION
EXTERNAL DC BIAS AT EXT BIAS CON-
NECTOR MUST NEVER EXCEED +40V.
13. Read measured value on display.
Note
It is usually recommended that the LCR RANGE
be set to MANUAL and to hold the range when
measuring multiple samples having almost the
same value. Range hold operation will somewhat
shorten measurement time.
Note
Series resistance of electrolytic capacitors, in-
ductors or transformers can be measured in series
R/ESR measurement mode. In these cases, the
number of digits is sometimes reduced. On the
other hand, resistance can, of course, be indirectly
measured with the C/L FUNCTION and cal-
culated from one of the following equations:
Rs = D/wCs (Cs-D measurement)
Rs = wLs- D (Ls-D measurement)
Rs=wlp- I—-P—Di (Lp-D measurement)
The above relationships are graphically shown
in Figure 3-6,
CAUTION
DO NOT CONNECT A CHARGED CAPACITOR
(EXCEEDING 40V) DIRECTLY TO THE UNKNOWN
TERMINALS AS A DUT.
CAUTION
NEVER APPLY A DC VOLTAGE DIRECTLY
BETWEEN THE UNKNOWN H AND L TERMINALS
WITHOUT PROPER PROTECTION AGAINST A
POSSIBLE HARMFUL CURRENT. DC VOLTAGE
MUST NOT BE APPLIED TO THE L TERMINAL
WITH RESPECT TO GROUND.
