F. CAPACITANCE MEASUREMENT
(see figure 8)
Warning
To avoid damages to the Meter or to the
equipment under test, disconnect circuit power
and discharge all high-voltage capacitors before
measuring capacitance. Use the DC voltage
function to confirm that the capacitor is
discharged. Never attempt to input over 60V in
DC or 30V rms in AC to avoid personal injury.
Capacitance measurement has 6 measurement
positions on the rotary switch : 4nF, 40nF, 400nF,

To measure capacitance, connect the Meter as
follows :
1)
Set the function/range switch on the range
position needed.
2)
Use SELECT button to select capacitance range.
3)
Insert the capacitance into the “Cx” jack.
The measured value is shown on the display.

The test leads can add 0.1

to 0.3
W
of error to
the Resistance measurement. To obtain
precision readings in low-resistance, that is the
range of 400
W
,
short-circuit the input terminals
beforehand and record the reading obtained
(call this reading as X). (X) is the additional
resistance from the test lead.
Then use the equation :
Measured resistance value (Y) - (X) = precision
Reading of resistance.
n
When there is no input, for example in open
circuit condition, the Meter displays “ 1”
When resistance measurement has been
completed, disconnect the connection between
the testing leads and the circuit under test.
Caution :
n
Never connect high voltage to the input
sockets with the switch in Resistance range.
n
Using Resistance measurement function in a
Live circuit will produce false results and may
damage the instrument. In many cases the
suspect component must be disconnected from
the circuit to obtain an accurate reading.
