2.3. Setting Under Voltage Level
In normal operation, press “SET” button. Press “UP” button untill “UdL” “SET” appears
on display. Pressing “SET” button again will indicate “Under Voltage Limit.” on the lowest
display Adjust the desired value and press “SET” button to save. Press “UP” button until
“ESC” appears on lowest display. Press “SET” button to Escape. After a short time device
will start displaying current, voltage and frequency values on the displays.
2.4. Setting Over Current Value
In normal operation, press “SET” button. Press “UP” button untill “IuL” “SEt” appears
on display. Press “SET” button again the lowest display will show “ “”Over Current Limit”
Adjust the desired value and then press “SET” button to save. Press “UP” button until
“ESC” appears on lowest display. Press “SET” button to Escape. After a short time device
will start displaying current, voltage and frequency values on the displays.
3. VIEWING CURRENT, VOLTAGE AND FREQUENCY
In normal operation, device displays current of three phases at the same time on first three
displays.
Fourth display shows the voltage of one phase and one of the three leds on left side of the
display lights. This LED indicates which line’s voltage is being displayed currently. Pressing
“UP” or “DOWN” buttons will change the current information of fourth display. User can
see voltage levels of three phases to neutral or phase to phase voltages by pressing one of
this buttons sequentialy. Each pressing of buttons will update the status of LEDs on left side
of fourth display by giving information to the user about which of the reading is to be
displayed. Fifth display gives information about line frequency in normal operation.
4. VIEWING MAXIMUM AND MINIMUM DEMANDS
Press “SET” button when device is in normal operation mode. Press “UP” button until
“LHı” appears on the lowest display. At this time first three displays give information about
maximum reading of currents for three phases. The fourth display shows maximum reading
for selected voltage line. Line selection is done by “SET” button in this operation status.
Each pressing of “SET” button will change information of fourth display and LED status as
well.
If user continues pressing “UP” button until lowest display shows “LLo” the first three
displays will give information about minimum reading of currents of three phases.Hence,
fourth display will show the minimum value of voltage for the selected line. Selection can be
done by “SET” button.
Keep pressing “UP” button until the lowest display shows “ESC” and then “SET” is
pressed to Escape . Consequently this will shift the device into its normal operation status by
which it gives information about voltage, current and frequency values.
IMPORTANT NOTE: MULTIMETER HAS TWO VERSIONS WITH THE ORDER NO; PM-
DM AND PM-DMR. PM-DM IS THE ONE WITHOUT CONTACT OUTPUTS AND NO-
