Operating Instructions
Energy Monitor

These operating instructions belong to this product.They contain important imformation for operation and handling. They must be observed, even if the product is passed on to a third party. In this regard,keep these operating instructions for future reference.

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.

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).

•  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 shor t circuit ,fire, electric shock,etx. The entrie product may not be converted or modified. The safety instructions must be strictly observed.

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.
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 possible if the devive shows visible damage, no longer works correctly, has been stored for a long period under unfavourable conditons or has been placed under heavy stesses in transport.
If the long time does not use, please take the Energy Monitor internal batteries preservation in the dry place.

Properties

• Monitoring of voltage, current, active power display Max value recording of voltage, current, active power.
• Display of used energy and accrued power costs.
• Cost forecast.

Connection, operation settings

Before you connect the Energy Monitor to an outlet or power load, 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 shor t circuit ,fire, electric shock,etx. The entrie product may not be converted or modified. The safety instructions must be strictly observed.

Replacing the battery

When the LCD loses contrast, immediately replace the battery of the device.
The Energy Monitor requires two 1.5V “AAA* batteries. For replacing the battery,proceed as follows:

• Turn the screw of the battery compartment and remove the battery compartment
• Remove the used batterty from the Energy Monitor and replace it with two new 1.5V “AAA” batteries. Observe correct polarity when inserting the battery.
• Replace the battery compartment cover and refasten the screw.

AdditIonal notes

Tice connected loads should be operated as normal when producing the cost forecast if an exact cost forecast is to be made per week/ month/year for a power load, we recommend leaving the energy monitor connected to the load for at least one day. The energy monitor can thereby calculate an average power/load and accrued costs more accurately. The longer the Energy Monitor is connected, the more accurate is the cost forecast.
The power supply on a power net is never constant and varies from place to place. For example, a voltage fluctuation of 1% per second for a calculated cost forecast over 5 minutes will never be as accurate as a cost forecast taken 3 hours.
Some devices use more current than others immediately after switching on. The current usage decreases the longer the device is use (warm -up phase).

Maintenance

1. Regularly inspect the Energy Monitor for damage.
2. For cleaning the device and LCD, only use a dry, soft cloth. Do not use any cleaning solutions.
3. Never immerse the device in water.
4. Maintenance or repairs may only be performed by a technician familiar with associated regulations
