Instrument Start-up – Fig. 1.2
Caution.
Ensure that all connections, especially to the earth stud, are made correctly – see Section 7.
Switch on the supply to the instrument, the input sensors and any power-operated control circuits.
Information.
• When powering the instrument from a DC supply, a PSU with a minimum current rating of 5A is recommended.
• Ensure that the voltage supplied is above 10V. If a lower voltage is applied, the unit draws a higher current on power-up.
If necessary, fit a switch in the supply line between the PSU and the instrument to ensure that the PSU is at the correct
voltage before powering the instrument.
