User manual VOLTCRAFT MULTI-DMM MT-52 V09-10

[. . . ] Do not go below or above this voltage, because the measuring results would be inaccurate and the module would be destroyed. If the operating voltage drops below 7 V, the display shows "battery". Replace the battery immediately or set the input voltage to the correct value. [. . . ] The display light can be switched on by applying a voltage of either 9 V/DC or 12 V/DC. The series resistors for the lights (LEDs) are integrated in the module. By means of individual, external circuits, other physical quantities such as direct current or temperatures can also be displayed. A display light is integrated; it can be supplied with the operating voltage or with 12 V/DC. The module must not be operated at voltages greater than 48 V/DC (by an optional volt-age divider). for a voltage over 48V the respective instructions concerning clearances to air and leakage paths for shock protection must be complied with. Always observe and adhere to the safe distance for dangerous contact voltages/wires. Carefully read the whole operating instructions before operating the device, otherwise there is risk of danger. Symptom The LCD shows "1" The LCD shows "-" Cause The measurement value is outside the measuring range. When used in conjunction with other devices, observe the operating instructions and safety notices of connected devices. Heat the soldered joint only as long as necessary and as short as possible. Repair works must only be carried out by a specialist/ specialist workshop. If you have queries about handling the device, that are not answered in this operating instruction, our technical support is available under the following address and telephone number: Voltcraft®, 92242 Hirschau, Lindenweg 15, Germany, phone 0180 / 586 582 7 In order to preserve, protect and improve the quality of environment, protect human health and utilise natural resources prudently and rationally, the user should return unserviceable product to relevant facilities in accordance with statutory regulations. The crossed-out wheeled bin indicates the product needs to be disposed separately and not as municipal waste. [. . . ] The crossed-out wheeled bin indicates the product needs to be disposed separately and not as municipal waste. All the connections and functional soldering links are made on the back of the module.
