MEASUREMENT OPERATION
A. DC AND AC VOLTAGE MEASUREMENT (see figure 3)
(figure 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 effect 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.
