5. MEASUREMENT TUTORIAL
5-1. Voltage measurements (DCV, ACV, DCmV, ACmV)
1).Press the button to select desired function.
2).Press [▲]or[▼]to the desired range (if you have no idea about the
value of input, we suggest you always start at the highest range).
Press [AUTO/MAN] button for manual or auto-ranging selection.
3).Connect the test lead to the V and COM input terminals of the
instrument.
4).Connect the test lead to the measuring points and read the displayed
value.
NOTE: After measuring high voltage to 1000V dc, errors may
occur when the 100μV is measured. Allow up to one
minute prior to making low-level measurements
5-2. Current measurements (DCA, DC 20A, ACA, AC 20A)
1).Press the button to select function.
2).Press [▲]or[▼]to the desired range (if you have no idea about the
value of input. we suggest you always start at the highest
range).Press [AUTO/MAN] button to change manual or
auto-ranging.
3).Connect the test lead to the 2A or 20A and COM input terminals of
the instrument.
4).Connect the test lead to the measuring points and read the displayed
value.

5-5. dBm measurements
This function converts a voltage measurement into dBm. The function
can be selected only when a voltage function (volts ac, volts dc, or
volts ac+dc) is selected. Press [dBm] button, the secondary display
shows the dBm value that reposed on the voltage value showed in the
primary display.
