Ac Voltage Measurement - Minipa MT-1400 Manual De Instrucciones

Note
• If the value of voltage to be measured is unknown, use the maximum
measurement position (500V) and reduce the range step by step until a
satisfactory reading is obtained.
• The LCD displays "1" indicating the existing selected range is overload;
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.
B. AC Voltage Measurement
Warning
To avoid harms to you or damages to the Meter from electric shock,
please do not attempt to measure voltages higher than 500V RMS
although readings may be obtained.
The AC voltage measurement positions are: 200V and 500V. To measure
AC Voltage, connect the Meter as follows, noting the Figure 2:
1. Insert the red test lead into the VΩmA°C°F terminal and the black test
lead into the COM terminal.
2. Set the rotary switch to an appropriate measurement position V
3. Connect the test leads across with the object being measured. The
measured value shows on the display, which is effective value of sine
wave (mean value response).
Note
• If the value of voltage to be measured is unknown, use the maximum
measurement position (500V) and reduce the range step by step until a
satisfactory reading is obtained.
