Wiring protection
As a power supply, an unstabilised DC power supply is sufficient in the range of
the specified limits. It is important to ensure that the applied power supply is at
least greater than the maximum required voltage drop from the external display
and evaluation units; i.e. the voltage at the instrument must not fall below 10 V.
