1. Introduction
The VOLTCRAFT Energie Logger 4000 F is a sophisticated device designed to measure and record electricity consumption. It allows users to monitor power usage for up to six months on its internal memory. Data can be easily transferred to a computer via an SDHC card (not included) for detailed analysis and storage. This enables identification of high-consumption appliances and supports efficient energy-saving measures. The device provides highly accurate readings, even for standby consumption, starting from 0.1 Watt.
2. Safety Instructions
- Read this manual thoroughly before operating the device.
- Ensure the device is used only with compatible power outlets and within specified voltage/current limits.
- Do not open the device casing, except for battery replacement as instructed.
- Keep the device away from water, moisture, and extreme temperatures.
- Do not use the device if it appears damaged.
- Dispose of batteries and the device according to local regulations.

4.1 Display
The 3-line display shows various electrical parameters, including:
- Current power consumption
- Apparent and effective power
- CosPhi factor
- Intensity (current)
- Voltage
- Frequency
- Minimum and maximum values recorded
4.2 Controls
The device features buttons for navigation and mode selection:
- MODE: To switch between different display modes and settings.
- MAX/MIN: To view recorded maximum and minimum values.
- Arrow Buttons: For navigating menus or adjusting settings.
5. Setup
5.1 Battery Installation
The device includes an integrated backup battery (3V CR1620) to retain measured data during power outages. To access the battery compartment, you may need a precision screwdriver to remove small screws. Ensure correct polarity when inserting the battery.
5.2 SDHC Card Insertion
For data logging and transfer, an SDHC card (not supplied) is required. Locate the SDHC card slot on the device and insert the card gently until it clicks into place. Ensure the card is inserted in the correct orientation.
5.3 Initial Connection
- Plug the Energie Logger 4000 F into a standard wall socket.
- Connect the appliance you wish to monitor into the socket on the Energie Logger.
- The display will illuminate, showing initial readings.
6. Operating Instructions
6.1 Monitoring Energy Consumption
Once connected, the device automatically begins monitoring the power consumption of the attached appliance. The 3-line display provides real-time data.
6.2 Display Modes
Press the MODE button to cycle through different display screens. These screens may include:
- Real-time Measurement: Shows instantaneous values for voltage, current, power, etc.
- Cumulative Measurement: Displays total energy consumed over time.
- Cost Forecast: Provides estimated monthly or yearly costs based on current consumption patterns.
- Min/Max Values: Shows the lowest and highest recorded values for various parameters.
6.3 Viewing Historical Data
The device can display the consumption and daily expenses for the past 9 days directly on its screen. Use the arrow buttons to navigate through these historical records.
6.4 Determining Operating Time
The Energie Logger 4000 F also tracks and displays the total operating duration of the connected appliance.
6.5 Measuring Standby Consumption
With its high accuracy down to 0.1 Watt, the device is ideal for precisely measuring the low power consumption of appliances in standby mode.
7. Data Transfer and Analysis
The Energie Logger 4000 F stores consumption data for up to six months internally. To access this data for detailed analysis:
- Ensure an SDHC card is inserted into the device.
- Follow the on-screen prompts or refer to the device's menu to initiate data transfer to the SDHC card.
- Safely remove the SDHC card from the Energie Logger.
- Insert the SDHC card into a computer's card reader.
- Use compatible software (often provided by VOLTCRAFT or available for download) to view, analyze, and store the collected data. This software typically allows for graphical representation and export of data.
8. Maintenance
8.1 Cleaning
Wipe the device with a soft, dry cloth. Do not use abrasive cleaners or solvents. Ensure the device is unplugged before cleaning.
8.2 Storage
Store the Energie Logger in a cool, dry place, away from direct sunlight and extreme temperatures, when not in use for extended periods.
8.3 Battery Replacement
If the backup battery (CR1620) needs replacement, follow the instructions in Section 5.1. A depleted backup battery may result in loss of stored data during power interruptions.
9. Troubleshooting
- No Display: Check if the device is properly plugged into a live power outlet.
- No Readings: Ensure the appliance is correctly connected to the logger and is powered on.
- Data Loss During Power Outage: Verify that the internal backup battery (CR1620) is correctly installed and has sufficient charge.
- SDHC Card Not Recognized: Ensure the SDHC card is inserted correctly and is formatted to a compatible file system (e.g., FAT32). Try a different SDHC card if issues persist.
- Inaccurate Readings: Ensure the device is used within its specified operating parameters.
