MEASUREMENT OPERATION
A. DC AND AC VOLTAGE MEASUREMENT (see gure 3)
(gure 3)
Warning!
To avoid harms to you or damages to the Meter from electric shock, never attempt to
measure voltages higher than 1000 or 1000V rms although readings may be obtained.
The DC Voltage ranges are: 200mV 2V, 20V, 200V and 1000V.
The AC Voltage ranges are: 2V, 20V, 200V and 1000V.
To measure DC Voltage, connect the Meter as follows:
1. Insert the red test lead into the VΩ input terminal and the black test lead into the COM
input terminal.
2. Set de rotary switch to an appropiate measurement position in or range.
3. Connect the test leads parallel across with the object to be measured.
The measured value shows on the display.
Note
• If de value of voltage to be measured is unknown, use the maximum measurement
position (1000V) and reduce the range step by step until a satisfactory reding is obtained.
• The LCD displays “1” indicating the existing selected range is overloaded , it is required
to select a higher range in order to obtain a correct reading.
• In each range, the Meter has an input impedance of approx. 10MΩ this loading eect can
cause measurement errors in high impedance circuits. If the circuit impedance is less than or
equal to 10kΩ the error is negligible (0.1% or less).
• When DC voltage measurement has been completed, disconnect the connection
between the testing leads and the circuit under test, and remove the testing leads away from the
input terminal of the Meter.
8
B. DC AND AC CURRENT MEASUREMENT (see gure 4)
(gure 4)
Warning!
Never attempt an in-circuit current measurement where the open circuit voltage
between terminals and ground is greater than 60V DC or 30V rms in AC.
If the fuse burns out during measurement, the Meter may be damaged or the operator
himself may be hurt. Use proper terminals, function, and range for the measurement.
When the testing leads are connected to the current terminals, do not parallel them
across any circuit.
The DC Current Measurement has 3 measurement positions on the rotary switch: 2mA,
200mA and 20A.
The AC Current Measurement has 3 measurement positions on the rotary switch: 20mA,
200mA and 20A.
To measure current, do the following:
1. Turn o power to the circuit. Discharge all high-voltage capacitors.
2. Insert the red test lead into the 20A or mA input terminal and the black test lead into the COM
terminal.
When you measure current below 200mA, please insert the red test lead into the mA input
terminal. When you measure 200mA or above, insert the red test lead into the 20A input
terminal.
3. Set the rotary switch to an appropriate measurement position in or range.
4. Break the current path to be tested. Connect the red test lead in serial to the more positive
side of the break and the black test lead to the more negative side of the break.
5. Turn on power to the circuit.
The measured value shows on the display.
9
Note
• l If the value of current to be measured is unknown, use the maximum measurement
position, and reduce the range step by step until a satisfactory reading is obtained.
• l For safety sake, the measuring time for high current should be less than 10 seconds
and the interval time between 2 measurements should be greater than 15 minutes.
• l When current measurement has been completed, disconnect the connection between
the testing leads and the circuit under test, and remove the testing leads away from the input
terminal of the Meter.
C. MEASURING RESISTANCE (see gure 5)
(gure 5)
Warning!
To avoid damages to the Meter or to the devices under test, disconnect circuit power
and discharge all the high-voltage capacitors before measuring resistance.
The resistance ranges are: 200Ω, 2kΩ, 20kΩ, 2MΩ and 200MΩ.
To measure resistance, connect the Meter as follows:
1. Insert the red test lead into the VΩ input terminal and the black test lead into the COM
terminal.
2. Set the rotary swich to an appropriate measurement position in Ωrange.
3. Connect the test leads parallel across with the object being measured.
Note
• The test leads can add 0.1Ω to 0.3 of error to the slow-resistance (200Ω) measurement.
• For high resistance (>1MΩ), it is normal taking several seconds to obtain a stable
reading.
• 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, and remove the testing leads away from the input
terminal of the Meter.
10
D. MEASURING DIODES AND CONTINUITY (see gure 6)
(gure 6)
Warning!
To avoid damage to the Meter or to the equipement under test, disconnect circuit
porwer and discharge all high-voltage capacitors bere measuring diodes.
To avoid harms to you, never attempt to input voltages higher than 60V DC or 30V rms
in AC.
Measuring Diodes:
Use the diode test to check diodes, transistors, and other semiconductor devices. The diode
test sends a current through the semiconductor junction, and then measures the voltage drop
across the junction. A good silicon junction drops between 0.5V and 0.8V.
To test out a diode out of a circuit, connect the Meter as follows:
1. Insert the red test lead into the VΩ input terminal and the black test lead into the COM
terminal.
2. Set the rotary swich to .
3. For forward voltage drop readings on any semiconductor component, place the red test lead
on the component’s anode and place the black test lead on the component’s cathode.
The measured value shows on the display.
Note
• In a circuit, a good diode should still produce a forward voltage drop reading of 0.5V to
0.8V; however; the reverse voltage drop reading can vary depending on the resistance of other
pathways between the probe tips.
• Connect the test leads to the proper terminals as said above to avoid error display. The
LCD will display “1” indicating open-circuit for wrong connection. The unit of diode is Volt (V),
displaying the positive-connection voltage-drop value.
• The open-circuit voltage is around 3V.
• When diode testing has been completed, disconnect the connection between the testing
leads and the circuit under test, and remove the testing leads away from the input terminal of
the Meter.
