Meter Functions – Capacitance (CAP)
IMPORTANT: Turn the power OFF to the test circuit
Ñ
Select the Capacitance "CAP"
function with the rotary switch
and mode button
Insert:
Ñ
Black lead in COM terminal.
Ñ
Red lead in V-Ω-RPM terminal
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.
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.
