Measuring AC voltage
1.
Insert the black test lead into COM terminal. For current ≤200mA, insert the red test lead
into mA terminal. If current goes up to 10A, insert red test lead into 10A terminal.
2.
Set the rotary switch to A
Notice
1. Refer to Notice 1, 2 and 3 in the Direct Current Measurement.
Measuring Resistance
1.
Insert test leads into input terminals (Red to Ω and black to COM).
2.
Set the rotary switch to Ω range. Connect test leads to tested resistor in parallel.
Notice
1.
If the resistance to be tested is more than the maximum value of the range selected, over-
range "1" will be shown. You shall select higher .
2.
When input is not made, such as open-circuit conditions, the instruments shows "1".
3.
When you check the impendence of internal circuits, power supply to the circuit to be tested
must be cut off and all capacitors must be totally discharged.
4.
There are 10 digits at 200MΩ short-circuit which shall be subtracted from the reading. For
example, 101.0 is shown in measurement of 100MΩ resistance and the 10 digits shall be
subtracted.
Measuring Capacitance
Prior to connection to the capacitance to be tested, note that time for zero reset is needed
for each change of range. Existing drift reading cannot influence the testing precision.
Notice
1.
Although the capacitance ranges have been protected internally, you still need to discharge
all tested capacitors so as to avois any damage to the instrument or any measurement
error.
2.
In measuring capacitance, insert the capacitor into the capacitance testing seat.
3.
In measuring large capacitance, it will take a certain time period to get stable reading.
4.
Unit: 1pF=10
ɥF, 1nF=10

Measuring Frequency
1.
Insert test leads into imput terminals (Red to Hz and black to COM)
2.
Set the rotary swich to kHz range; Connect test ledads to frequency source. You can read
the frequency reading directly from the display.
18
range; Connect test leads to the tested circuit in series.
