Operation and LCD-Display
The real Time Clock (RTC) is built-in in the PM-30E. In addition to serving as a calendar and clock
for all measured demand, maximum and minimum archieving, it also does all the synchronization
of the averaging of all measurements.
RTC - Real Time Clock
Demand Parameter
As standard the PM-30E is measuring the 28 Parameters over an adjustable time
span of 5, 10 or 15 minutes. These are displayed on the LCD by pressing the demand button.
Max- und Min- Peak Parameter
The PM-30 enhanced version measures and stores the highest and the lowest current and voltage
peaks (2 seconds mean average value) stored with the time, day and date in the nonvolatile
memory automatically. These can be viewed on the LCD from the corresponding button.
The PM-30E is an efficient digital electrical multimeter. It can measure and display up to 120
electrical parameters using true RMS measurement. The PM-30E is ideal for all kind of installation
on low, medium and high voltage switchgear and inside control rooms, where precise and
reliable measuring device is always wanted for power generation, sub-stations and energy
management.
The PM-30E is housed in a switchboard case according to DIN 43700 with a compact size
144 x144x75 mm. Its shallow depth of 75mm inclusive of terminals makes it easy to install it in
shallow panels. The PM-30E is designed with large LCD to display large texts. The module is
designed to withstand operating temperatures up to 70C. The wiring of the module is via pluggable
terminals. On request the PM-30E can be delivered for DIN Rail mounting.
Setup and operation of the module is made easy using 15 buttons membrane keyboard. Each of
the major parameter has its own button designated by its mathematical symbol. This makes it easy
to directly go to the required pararmeters and avoid scrolling up and down.
The setup page is user friendly. Through which the CT and VT ratios can be set. When the module
is fitted with Real time clock (RTC) it is also possible to set up the clock and the calendar. The
module language can also be selected from the set up page (either English or German).
Max- and Min- Demand Parameter
The PM-30E enhanced version has the capability to measure and display the minimum and the
maximum demand value of all the 28 main parameters. This gives total of 56 values. The values
are stored automatically in the nonvolatile memory, which can be viewed on the LCD by pressing
the corresponding buttons.
