Note:
1. In order to obtain an accurate reading, a capacitor must be discharged before measurement begins. The
chip has a built-in discharge mode to automatically discharge the capacitor. In discharge mode, the
LCD displays dIS.C
2. Discharging through the chip is quite slow. We recommend the user to discharge the capacitor with
some other apparatus.
3. In C7~C8 ranges, the bargraph is used to show the measured time in counting down.
4. The C2 range is calibrated by VR near the OVX pin.
5. In ranges of C1~C8, the SHIFT feature is also available to move the digits and decimal points
rightward to prevent the least digit from jumping.
1.6 Continuity Check
Continuity check shares the same configuration with 220.00Ω manual resistance
measurement mode, but with buzzer output to indicate continuity. The buzzer generates a
2KHz sound whenever the digit number is less than 30Ω.
1.7 Diode Measurement
Diode measurement mode shares the same configuration with 2.2000V manual voltage
measurement mode.. The buzzer generates a 2KHz sound whenever the digit number is
less than 30mV. When the LCD display counts are larger than 1.9000V, the OL will be
shown.
