Av Voltage Testing - EGAmaster EGAtronik 51259 Manual De Instrucciones

Warning!
To avoid harms to you or damages to the Meter from electric shock, please do not attempt to
measure voltages higher than 1000Vp although readings may be obtained.
Please take extra care when measuring high voltages to avoid electric shock.
The AC voltage ranges are: 200V and 750V.
To measure AC voltage, connect the Meter as follows:
1. Insert the red test lead into the V terminal and the black test lead into the COM terminal.
2. Set the rotary switch to an appropriate measurement position in
3. Connect the test leads across with the object beingmeasured.The measured value shows on
the display. It is theeffective value of sine wave (mean value response).
Note
- If the value of voltage to be measured is unknown,use the maximum measurement position
(1000V) andreduce the range step by step until a satisfactoryreading is obtained.
- The LCD displays "1" indicating the existing selectedrange is overloaded, it is required to select
a higherrange in order to obtain a correct reading.
- In each range, the Meter has an input impedance ofapprox. 10MΩ. This loading effect can
causemeasurement errors in high impedance circuits. If thecircuit impedance is less than or equal
to 10kΩ, the error is negligible (0.1% or less).
- When AC voltage measurement has been completed,disconnect the connection between the
testing leadsand the circuit under test.
