In order to set the default measurement mode when the device is turned on, select the mode, press the
jog-wheel and hold for 2 beeps. This measurement setting will be
stored in the device’s non -volatile
memory for all other measurements until selecting other parameters or Default in the menu.
7.2.10 Large Cap
In this mode, capacitance and ESR of capacitors from 1 μF to 40 mF are measured. The capacitance is
measured at a frequency of 50Hz, and the capacitor's ESR is measured at the frequency of 100 kHz.
Discharge Capacitors before testing!
If open p-n junctions of semiconductor components cause an error in the measurements, then the
screen shows the diode symbol and the direction of the p-n junction is shown instead of the primary
parameter type.
If the resistance of the component is less than 10 ohms, there will be short beeps. Before the first
application in this sub-mode it is necessary to calibrate the device with both open and shorted probes.
For the rejection of electrolytes based on ESR, two tables are stored in the memory of the device, one
for standard aluminum capacitors and the other for
Low ESR capacitors. Two additional numbers are
displayed on the screen in this case: the first number is the quality of the capacitor. For standard
aluminum capacitors, positive values indicate rejection, and for
Low ESR rejected values are above -10.
The second number is selected operating voltage of the capacitor in menu under C voltage: 6.3, 10, 16,
2, 3, 50-63, 100, and 160+ Volts. This menu opens by clockwise turn of the jog-wheel.
7.2.11 Large Cap (1 uF to 40 mF) Settings
•
Clockwise for 1 beep to open the mode menu.
•
Clockwise for 2 beeps to make calibration eliminating the offset. Only short calibration is
required.
•
Counter clockwise for 2 beeps to toggle the test signal level between 0.65 Vrms and 0.1
V peak-to-peak.
7.2.12 Super Large Cap > 40 mF Measurement
• When in the Large Cap mode, counter clockwise for 1 beep to switch to DC capacitance
measurement mode for Capacitors larger than 40 mF up to 680 mF. To speed up the settling
of the readings, short the capacitor leads for 2-3 seconds before the measurements. Counter
clockwise for 1 beep again to return to the normal Large Cap mode.
