5.5. CAPACITANCE MEASUREMENT

Before carrying out capacitance measurements on
circuits or capacitors, cut off power supply from the
circuit being tested and let all capacitance in it be
discharged. When connecting the multimeter and the
capacitance to be measured, respect the correct polarity
(when required)

2. Press the MODE/
3. Insert the red cable into input terminal VHz%mACAP
and the black cable into input terminal COM
4. Position the leads at the ends of the capacitor to be tested,
respecting, if necessary, the positive (red cable) and negative
(black cable) polarity (see Fig. 7). The display shows the value of
capacitance

5. The message OL
exceeds the maximum measurable value
6. To use the HOLD function, see § 4.2

5.6. DC CURRENT MEASUREMENT

Maximum input DC current is 10A (input 10A) or 400mA
(input VHz%mACAP
exceeding the limits given in this manual. Exceeding
voltage limits could result in electrical shocks to the user
and damage to the instrument

terminal COM.
5. Connect the red lead and the black lead in series to the circuit
whose current you want to measure, respecting polarity and
current direction (see Fig. 8).
6. Supply the circuit to be measured. The display shows the value
of current.
7. If the display shows the message "OL", the maximum
measurable value has been reached.
8. When symbol "-" appears on the instrument's display, it means
that current has the opposite direction with respect to the
connection in Fig. 8.
9. To use the HOLD, RANGE and MAX MIN functions, see § 4.2
