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.
