3 - 4 Power up the MAMMOMAT Stand
Measuring the line resistance 3
1. Connect the line resistance meter to the mains input terminal on the stand.
2. Mains supply ON.
3. Carry out measurement.
4. Mains supply OFF.
To achieve the maximum output, the line resistance must not exceed the following values:
Checking the supply voltages 3
The correct supply voltages +5 V, +15 V and +28 V have already been tested in the fac-
tory. Only a visual check of the function is therefore needed.
1. Switch the system ON.
2. Check that the following LED indicators (top to bottom) on the mains input
converter (generator) are on:
