The Chroma 11020 Capacitance Meter is a high-speed
precision Capacitance Meter. Provides 100Hz, 120Hz, and
1kHz test frequencies. Measurement time is only 5
milliseconds in 1kHz, and less than 15 milliseconds in
100Hz and 120Hz test frequencies. Combine with 0.1%
basic accuracy and standard Handler interface, enable
the Chroma 11020 to be used on high speed production
line for various capacitors.
100Hz, 120Hz and 1KHz test frequencies
100Hz and 120 Hz test frequencies are
generally used in capacitance measurement of
electrolytic capacitors which are used as power line
voltage rectifiers. 1KHz is generally used in
capacitance measurement of ceramic and film capacitors.
5ms measurement in 1KHz
For high speed
capacitance check in the ceramic capacitor automatic
production line and package machines, the Chroma 11020
uses digital sampling technology to perform a 5ms high
speed measurement with high accuracy.
15ms measurement in 100Hz/ 120Hz
period of low frequency as 100Hz is long as 10ms. This
causes longer measurement time for general LCR meter or
capacitance meter. The Chroma 11020 uses high speed
digital sampling technology to shorten sampling time to
1 period, to perform an excellent measurement speed in
low frequency capacitance measurement. This is great
help in electrolytic capacitor automatic production.
Large capacitance measurement
larger than 100mF is extremely difficult in capacitance
measurement because of extremely low impedance in
100Hz/120Hz. The Chroma 11020 keeps excellent
measurement accuracy in low impedance measurement for
large capacitance measurement.
0.01 pF measurement resolution
meter or capacitance checker provides 0.1pF measurement
resolution only. The Chroma 11020 provides 0.01pF
measurement resolution, which is proper to be used in
low capacitance ceramic , mica, PS capacitors out-going
The Chroma 11020 has
comparator function to judge HI/GO/LO of capacitance
measured result, and to judge GO/NG of D factor. And an
alarming beeper for total GO/NG judge.
Trigger Delay Time
For large capacitance
measurement in automatic production, a RC (meter output
resistance and unknown capacitance ) delay time for test
signal transient is necessary. The Chroma 11020 provides
trigger delay time for it, and is convenience for
automatic equipment timing adjustment.
