5 Measuring Direct Alternating Voltage
You can measure direct voltage, as well as sinusoidal alternating
voltage with frequencies ranging from 45 to 65 Hz, with this test
instrument.
Select Measuring Function
➭ Select the V measuring function with the rotary switch.
Connection
➭ Connect the measurement cables to the + and COM jacks.
➭ Contact the measuring point with both test probes.
Set the waveform parameter (voltage type).
Measurement
The measured value is displayed directly (without pressing the
START key) – in analog format at the bar graph and in digital format
at the matrix display.
➭ After completing the measurement, switch the instrument off
by turning the rotary switch to the OFF position.
The ESC, START and CONTIN. keys have no function in this case.
Note
Input impedance for the voltage measuring range is
10 MΩ.
