Optical IR interface

The measuring device is equipped with an optical interface. The galvanic separation of the measuring device from the PC prevents damage to the PC caused by excess voltage. The optical interface is located at the top of the measuring device on the front. It serves to transfer data to a PC for further processing.
- Establish the interface connection with the IR-USB interface cable by connecting this to a free USB port on your PC. - Plug the IR-USB interface cable into the optical interface on the top front side of the measuring device. - Install the provided demo software or another optionally available measuring software to process the measuring data. - Observe the installation and operating instructions on the CD-ROM.
Optional power pack operation
For longer operation or permanent measuring, the measuring device can be operated with an optional power pack. The power pack is connected on the left side of the measuring device. The power pack may only be operated with mains voltage from V~ 50 Hz.

For safety reasons, only the offered optional power pack may be used with the DMM. The use of a different power pack may result in a fatal electric shock.
It is not possible to charge accumulators in the measuring device with the power pack unit. Accumulators must be removed from the measuring device for charging and charged with an optional charger. Due to the fact that the voltage supply in the battery compartment is interrupted when using the power pack, the batteries may remain in the measuring device. However, you should remove the batteries from the measuring device in case you operate it for longer periods with the power pack (danger of leaking).

Servicing and cleaning

General
To ensure the accuracy of the multimeter over an extended period of time, it should be calibrated once a year. Information on changing the battery and fuse appears below.
Periodically check the technical safety of the instrument and measuring lines, e.g. check for damage to the housing or squeezing etc.

Cleaning

Always observe the following safety instructions before cleaning the device: Live components may be exposed if covers are opened or parts are removed (unless this can be done without tools).
All connected cables must be disconnected from the instrument before servicing or repair work is performed. Do not use cleaning agents which contain carbon, petrol, alcohol or similar substances for cleaning purposes. These could corrode the surface of the measuring instrument. The vapours are also detrimental to health and are explosive. Sharpedged tools such as screwdrivers or metal brushes should not be used for cleaning purposes. To clean the device, the display or measurement lines, use a clean, dry lint-free antistatic cleaning cloth.

Replacing the fuse

Always adhere carefully to the safety instructions, if you replace fuses! Make sure that only fuses of the type stated and rated current specied are used as a replacement. Using repaired fuses or bridging the fuse bracket is not permitted.
The DMM is protected against overloading. The two current measuring inputs (5 und 9) are each protected with a ne fuse. If measuring is no longer possible, you have to exchange the fuse. Proceed as follows to change the fuse: - Remove all measuring leads and turn the multimeter off. - Unscrew the battery compartment screw (10) on the back of the device and take off the battery compartment cover (12). - Unscrew the three casing screws (11) and carefully remove the cover of the DMM until you can access the fuses on the bottom of the DMM. - Replace the defect fuse with a new one of the same type and current. - Carefully replace the back cover on the DMM and screw the back cover shut again with the three casing screws (11). Make sure that the battery compartment plug connection does not become detached from the main circuit board when changing the fuse. - Replace the battery compartment cover (12) on the battery compartment and screw it shut with the battery compartment screw (10). Only the following fuses may be inserted: Measuring range up to 400mA: Fuse Flink 400mA/250V Measuring range up to 10A: Fuse Flink 10A/250V

Inserting/changing the batteries/accumulators
Four mignon cells are required for operating the measuring device. You have to insert new, charged mignon cells for initial operation or when the battery change symbol appears on the display. You can use NiCD, NiMH accumulators or alkaline batteries for operating the DMM. For reasons of environmental protection, you should use NiMH accumulators. We recommend using high-capacity accumulators. Proceed as follows to insert or change the batteries: - Disconnect your measuring instrument from the measurement circuit. - Remove all measuring leads from the DMM and turn it off. 47
- Loosen the battery compartment screw (10) and carefully lift off the battery compartment cover (12). - Now place four new mignon batteries in the battery compartment, observing the correct polarity. Observe the polarity indication in the compartment. - Now close the casing carefully.
Never operate the measurement device when it is open. !RISK OF FATAL INJURY!
Do not leave at batteries/accumulators in the device. Even batteries/accumulators protected against leaking can corrode and thus release chemicals which may be detrimental to your health or destroy the device. If you do not operate the device for longer periods or if you operate it with the optional power pack, you must remove the batteries/accumulators from the device - danger of leaking!
Disposal of used batteries/accumulators
As the end user, you are required by law (regulation on disposal of batteries) to return all used batteries rechargeable and non-rechargeable batteries. Disposing of batteries in the household waste is prohibited. Batteries/rechargeable batteries containing hazardous substances are marked by the symbols alongside. These symbols also indicate that it is prohibited to dispose of these batteries in the household waste. The designations for the crucial heavy metals concerned are as follows: Cd = cadmium, Hg = mercury, Pb = lead. You can hand in your used batteries at the official collection points of your community or everywhere where batteries are sold. You will thus carry out your legal obligations and contribute to the protection of our environment.

Disposal

Old electronic devices are hazardous waste and should not be disposed of in the household waste. If the device has become unusable, dispose it in accordance with the valid statutory regulations.

Troubleshooting

In purchasing the DMM, you have acquired a product which has been designed to the state of the art and is operationally reliable. Problems and malfunctions may, however, still arise. For this reason, the following is a description of how you can eliminate possible malfunctions yourself.
