Meter Functions – Capacitance (CAP)

IMPORTANT: Turn the power OFF to the test circuit

Select the Capacitance “CAP”

function with the rotary switch

and mode button

Insert:

Black lead in COM terminal.

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:

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.

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”

Discharging through the chip is quite slow. We recommend the

user to discharge the capacitor with some other apparatus.
