Problems when turning the power on
1. MS does not turn on
Check the power supply.
□ Is the power supply voltage within the required range for the MS?
MS required voltage: 100V C 10%
□ Is the power cable connected correctly?
□ Is the wiring correct?
Check the power switch.
□ The power switch is on the instrument rear panel. Is it in the ON (1) position?
Hint
The power supply switch incorporates a no-fuse breaker (NFB) function.
The breaker is operating if the switch returns after being turned on (but it does not
return fully). This indicates a problem in the power line of the MS main power unit.
