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 main-display
shows dIS.C
2. Discharging through the chip is quite slow. We recommend users to discharge the capacitor with some other
apparatus.
3. The C2 range is calibrated by the VR near to the OVX pin.
4. The C1 range zero offset could be compensated by the small capacitors near to OVH pin.
5. When capacitance measurement (Clamp mode) is selected, C7-C8 range measurement period will be
double.
2.7 Continuity Check
Continuity check shares the same configuration with 660.0Ω manual resistance
measurement mode and has buzzer output to indicate continuity. The buzzer generates
2KHz beep whenever the reading is less than 30Ω.
2.8 Diode Measurement
Diode measurement mode shares the same configuration with 6.600V manual voltage
measurement mode and has buzzer output to indicate continuity. The buzzer generates a
2KHz sound whenever the reading is less than 30mV. If the test circuit is open or the
voltage drop between the two ports of the device(diode) under test is larger than 2V, the
LCD panel will show “OL”.
