Demonstration Case DB 1 1 Introduction The demonstration case BENNING DB1 has been designed in order to be able to present measuring instruments, current clamps and voltage testers as quickly as possible. This operating manual contains information that is necessary for proper operation of the device. Please read this operating manual thoroughly in order to ensure proper and safe operation of the device.
Demonstration Case DB 1 2 Safety instructions The device has been built and tested in accordance with the applicable regulations (see chapter 3) and has left the factory in perfectly safe technical condition. To preserve this condition and to ensure safe operation of the device, the user must observe the instructions and warnings given in this operating manual at all times. The device complies with category I. It must be connected to a single-phase mains with 230 V, 50Hz, pre-fuse 16A only.
Demonstration Case DB 1 3 Applicable regulations Measurements / tests BetrSichV BGV A3 (German Health and Safety at Work Regulation) Demonstration case (testers and measuring instruments) DIN EN 60529 (VDE 0470 Part 1) DIN EN 61010-1 (VDE 0411 Part 1) DIN EN 61326 –1 (VDE 0843 Part 20-1) 4 (IP) (device) (EMC) Device description For its active output voltages, the BENNING demonstration case requires a mains voltage of 230 V 50 Hz.
Demonstration Case DB 1 4.1 Measuring / testing Connect the device to the mains. The IEC connector with two fuses and a mains switch is situated at the rear. Connect it to the enclosed mains cable and a shockproof socket (230 V). The device is immediately ready for operation. AC current measurement AC current measurements are carried out by means of a current clamp. Set the switch to position I (the lamp lights) and enclose the semicircular current loop by means of the current clamp.
Demonstration Case DB 1 Resistance test, Set the function of the multimeter to position resistance / ohms and connect the measuring lines (or the DUSPOL tester with continuity test) to the measuring jacks for resistance. Read the measured value or observe the maximum measured value of the DUSPOL voltage tester respectively! The multimeter displays the resistance values in ohms (22 / 1k / 470 k). Diode test Set the function of the multimeter to position diode / .

Demonstration Case DB 1 4.3 Technical data Mains connection: 230 V ± 10 %, 50 - 60 Hz Current consumption: approx. 0.6 A Max. pre-fuse: 16 A Built-in microfuse (F1, F2): T 1 A (250 V, 5x20) Current load of the voltage measuring jacks and the test socket max. 0.2 A – for short-time operation only! Temperature fuse (in the transformer) 80 °C AC current measurement (7 windings) (halogen lamp 12 V 5 W) display, approx. 2.
Demonstration Case DB 1 5 Maintenance On the mains side, the device is protected by means of two microfuses. For fuse replacement, it is absolutely important to disconnect the mains cable and thus to make sure that the device is free of voltage! The microfuse holder is situated at the rear of the device. Use fuses of the same type and characteristic only! In case of longer overload or load, the thermal fuse integrated in the transformer will be triggered (all output voltages are switched off).
