In this case two additional figures are displayed. The first number is the quality of the capacitor. For
standard aluminum capacitors a positive number indicate rejection, and for
Low ESR values above -10.
The 2nd number is the selected operating voltage of the capacitor. It can be specified in the menu item
Large Cap/C-voltage .
Discharge Capacitors before testing!
7.1.2 Quick Controls
•
Turn the jog-wheel clockwise* and hold for 1 beep to change the test parameters (more info
below)
•
Turn the jog-wheel counter clockwise and hold for 1 beep to change the test frequency. The
frequency changes cyclically Auto-100Hz-120Hz-1kHz-10kHz-100kHz. If the frequency is selected
from the menu in the range 20-75kHz, the frequency changes cyclically 20kHz-30kHz-40kHz-
50kHz-60kHz-75kHz-100kHz
•
Turn the jog-wheel clockwise and hold for 2 beeps to eliminate the offset. If the probes are
shorted, parasitic resistance is obtained. If the probes are open, parasitic capacitance is
obtained. Please use LCR-Reader Calibration Board to set a proper distance between the test
leads (according to the component size) because the parasitic capacitance depends on the
distance.
•
Turn the jog-wheel counter-clockwise and hold for 1 beep to toggle the signal level between
Auto and fixed 0.65Vrms
•
If the probes are not connected to anything, press and hold up to 2 beeps to toggle the test
frequency between Auto and 100 kHz. If a part is connected to the probes, then relative
measurements are made showing the difference from the first measured component. Additional
symbol in the top-middle of the screen is displayed.
*When connected to the Capacitance is greater
than 1
μ F range for the operating voltage
7.1.3 Open/Short Calibration
Before the first use, the device must be calibrated with Open and Short probes for each test frequency.
When the device is set to Auto-frequency the device automatically calibrates at 100Hz, 1 kHz, 10kHz,
and 100kHz.
To eliminate the offset, turn the jog-wheel clockwise, hold for 2 beeps and release. When measuring
small capacitances less than 100 pF, use LCR-Reader Offset Calibration Board included in the package.
