16 MMD 540H Hybrid Multimeter Meter Functions
Meter Functions – Capacitance (CAP)
IMPORTANT: Turn the power OFF to the test circuit
ÑSelect the Capacitance “CAP” function with the rotary switch and mode button
Insert:
ÑBlack lead in COM terminal.
ÑRed lead in
CAUTION: When checking in- circuit capacitance, be sure that the circuit has all power removed and all capacitors are fully discharged.
Touch the test lead probes across the capacitance circuit to be tested. Read the measured value from the LCD display.
NOTE:
1. The bar graph is disabled in
capacitance measurement mode.Black–Red+ However, since the measurement
time of 4mF and 40mF modes is quite long (3.75s and 7.5s
respectively, to be precise), the bar graph is instead used to display the time required to accomplish the measurement.
2.In order to obtain an accurate reading, a capacitor must be discharged before measurement begins. The meter has a built- in discharge mode to automatically discharges the capacitor. In discharge mode, the LCD displays “DIS.C”
3.Discharging through the chip is quite slow. We recommend the user to discharge the capacitor with some other apparatus.
