Model UT58D: OPERATING MANUAL

Measurement Operation(10)

To measure capacitance, connect the Meter as follows:

1. According to the size of the tested object’s leads, select

multi-purpose socket or test clip to insert into the mA

and V terminal.

2. Set the rotary switch to an appropriate measurement

position in Fcx range.

3. Insert the tested object into the corresponding jack of

the multi-purpose socket or connect the test clip to

the object being measured.

The measured value shows on the display.

Note

l If the value of capacitance to be measured is unknown,

use the maximum measurement position, and reduce

the range step by step until a satisfactory reading is

obtained.

l When the tested capacitor is shorted or the capacitor

value is overloaded, the LCD display “1”.

l To minimize the measurement error caused by the

distributed capacitor, the testing lead should be as

short as possible.

l To increase accuracy especially when measuring

small capacitance range 20nF, the correct reading

is subtracting the test lead open circuit value from

the display value.

l It is normal to take a longer time when testing a high

capacitor value.

l For testing the capacitor with polarity, connect the

red clip or red test lead to anode and black clip or

black test lead to cathode.

l When capacitance testing has been completed,

remove the testing leads away from the multi-purpose

socket, and remove multi-purpose socket or test clip

away from the input terminal of the Meter.
