regard,keep these operating instructions for future reference.
1 Introduction .
With the Energy Monitor, you have acpuired a measurement device
created according to the most current state of the art. You are now
able to determine power costs of your power loads in the easiest way.
The Energy Monitor meets with the safety and corresponds with the
repuirements of valid European and nationa guidelines.The conformity
was proven and the corresponding declarations are available from
the manufacturer.
In order to maintain this condition and ensure safe operation, you as
the user have to observe this operating manual.
2 Operation .
The measurement range of the energy Monitor extends from 50 to
3000W. If values fall below or exceed these limit values,exact
measurements are no longer possible.Also the device could be
overloaded and thereby destroyed.
The Energy Monitor has been developed for monitoring and measuring
electrical loads.
Although the Energy Monitor is very accurate, it is not officially certified
for usage by power companies and users for measuring power
expenditures.
•
The Energy Monitor is only certified for operation at 230V AC.The
•
maximum power of any connected load may not exceed 3000W
•
(max,current 13A).
6. Properties
•
Monitoring of voltage, current, active power display Max value recording
9
•
of voltage, current, active power.
8
•
Display of used energy and accrued power costs.
•
Cost forecast.
7 Connection, operation settings .
7 Before you connect the Energy Monitor to an outlet or power load,
6
the desired power tariff must be set.
Note : when has not turned on the AC230V electric power supply,
presses MODE key to be possible starting to carry on the function
establishment.
A. Display of supply voltage, load current, load active power values.
•
Immediately after the Energy Monitor
•
is plugged into an outlet, the supply
•
voltage, load active power and present
•
current consumption of the connected
•
loads is displayed in the LCD.
•
Press the "V,A,W"button select to
•
display of supply voltage, load current,
•
load active power values.
•
When supply voltage>250V AC; Load
•
current>13A; Load active power>3000W,
•
LCD will display "OL" and flash alarm.
•
Operation of the Energy Monitor is only pemitted in interior spaces
•
and dry environments,Usage in the open air is strictly forbidden.
•
Always observe the declarations on the identification labels of
•
connected power loads.
Another use than the one described above leads to damages to the
product and is also associated with dangers like short circuit ,fire,
electric shock,etx. The entrie product may not be converted or
modified. The safety instructions must be strictly observed.
3 Safety instructions .
We will not assume any liability for damages to items or persons
caused by improper handling or non-com-pliance with the safety
notices. Any warranty claim will become null and void in such cased.
It must be observed that the conductive ground wire is not broken
as this can plse lethal danger in the event of a malfunction.
This device is not a toy and does not belong in the hands of children.
Only connect the Energy Monitor to certified protected comtact outlets
230V AC/50Hz (10/16A)with a ground wire.
The connected load may mot exceed 3000W(13A).
The recommended operation temperature is between +10 and +40°C.
High temperatures, especially during measurement of large power
loads, lead to danger of overheating and can thereby permanently
destory the Energy Monitor.
B . Display current time setting
•
Press " TIME " button into current time mode.
•
Press " SET/CLR " button into setting mode, " Hour " or "Minute"
•
digital will flash display.
•
When " Hour " or " Minute " digital will flash display, press " UP
•
" DOWEN " button setting time.
•
Again press " SET/CLR " button the Energy Monitor into normal
•
display current time, when " Hour " or " Minute "digital will Static display.
C . Display the electricity consumption of electric energy billing explorer
•
and the setting of time and billing.
•
Press MODE button between LCD display on and hour.
•
Press MODE button between LCD display on and kwh, that mean
•
the total power consumption; at this time press the SET/CLR key
•
will clear all data .
•
Press MODE button between LCD display Time, mean the time of
•
current total power consumption; at this time press the SET/CLR
•
button to set the starting point of electricity time .
•
Press MODE button between LCD display display T1 and Time,
•
mean the start time of T1, now press the SET/CLR button to set the
•
starting point of T1 electricity time .
•
Press MODE button between LCD display display off, T1 and Time,
•
express the end of time of T1, now press the SET/CLR key to set the
•
starting point of T2 electricity time.
•
Press MODE button between LCD display display on, T1 and kwh,
•
mean the electricity consumption of period T1, now press the
•
SET/CLR key to set the Price of Electricity of T1 .
•
Press MODE button LCD between display on, T2, that means power
•
consumption of T2, now press the SET/CLR button to set the
•
electricity price of T2 time .
Avoid operating under adverse environmental temperatures and near
flammable gased, vapours and dust.
For reasons of safety, never allow the device to be operated when wet
or in a damp environment.
When cleaning or servicing, the device must be disconnected from
everysource of operation volatge.
Condesers in the device may still be charged, even if the device was
disconnected from all voltage sources.
In schools, training facilties, hobby and self-help workshops, pualified
personnel must supervise the operation of measurement units.
In commercial institutions, make sure you observe the accident
prevention regulations of the commercial trade organization for electric
installations.
Do not insert needles, metals or any oteh objects into the device.
If it has been ascertained that safe operation is no longer possible,
take the device out of opertation and secure it against accidental
reactivation. It can be ascertained that safe operation is no longer
