6. SWITCH FUNCTIONS
For a simple usage, the main functions of the instrument can be selected by rotating the
switch:
 Position "VOLTAGE": to be used to display voltage and corresponding harmonics
(see paragraph 6.1)
 Position "CURRENT": to be used to display current and corresponding harmonics
(see paragraph 6.2)
 Position "POWER": it permits you to display all the parameters measurable by
the instrument: voltage, current, active, reactive and apparent
power, power factor, cos

and energy (see paragraph 6.3)
 Position "ENERGY": to be used to display active, reactive and apparent power,
power factor, cos

and energy (see paragraph 6.4)
More practically, we may schematize the right procedure of use as follows:
1. Check and eventually modify the basic settings of the instrument
2. By rotating the switch, select the type of measurement to be taken
3. Connect the instrument to the electrical system to be tested
4. Evaluate the values of the parameters under test
5. If you want to record:
a) Decide what to record
b) Press MENU and check if the existing parameters meet your requirements
6. Connect the External Power Supply
7. Start the recording by pressing START/STOP.
