The measurements displayed (updated every second) are the following
Page 1 -Voltage, current, Cosø, three phase power.
Page 2 -Voltage, current, Cosø, power of phase L 1 (R)
Page 3 -Voltage, current, Cosø, power of phase L2 (S)
Page 4 -Voltage, current, Cosø, power of phase L3 (T)
Page 5 -Three voltages, neutral current, frequency, phase rotation of each phase
and three-phase
Page 6 -Instantaneous, average and maximum active power of the three phases
and three-phase
Page 7 -Instantaneous, average and maximum apparent power of the three phases
and three-phase
Page 8 -Instantaneous, average and maximum reactive power of the three phases
and three-phase
Page 9- Percentage harmonic distortion of the three phases and three-phase.
Page 10- Active and reactive power consumption, average Tg and average Cosø
of the three phases and three-phase.
The measurements shown on the display can be printed by pressing the function
keys under the word PRINT in the last line of the display.
The next function key (beneath MENU) is pressed for access to the function
programming and measurement selection procedure.
Even if we are now presented with a very large range of options, management o
these procedures is very simple thanks to the menu's tree structure. the operator-
instrument dialogue.
Movement through the tree structure is by means of the numerical keys and the
function keys. The specific function of the function keys are always indicated on the
last line of the display page. (See Fig. 1.2)
For example, the function key located under "BACKPAGE" is pressed to turn back
one page in the MENU branch, while the function key under IIMEASURE" takes the
operator back to measurement page 1.

1.3 HIGHLY VERSATILE
The main feature of this instrument, and the factor which makes it unique o
its kind, is its outstanding versatility and expandability.
The range of parameters monitored can be extended: for example. a special
interface provides current measuring capacity from 30 mA to 999 kA.
Other interfaces allow accurate readings to be obtained even with current
transformers (CT) other than the clamp meter provided. with different ratios.
In the same way, a special interface can be combined with the system's
voltage transformers (VT) for medium voltage measurements.
Direct current measurements can be made using a special interface and
clamp meter.
The VIP SYSTEM 3 / MK 3 can be connected to the telephone line using a
MODEM device to permit remote processing of data from a number of analy-
zers.
A special accessory (MEMORY PACK) allows a larege number of measure-
ments to be stored and then transferred to a remote printer or a computer.
Finally, the VIP SYSTEM 3 can be used to measure different types of parame
ters far specific purposes through the installation of special BLACK BOXES.
The BLACK BOXES for measurement (by means of a prometer ) of tempera-
ture in the range from -20 o C. to + 200 o C (- 4 o to + 424 °F) ., and o
system leakage current, respectively, are already available.
