3. Safety instructions
Whilst the hardware and software has been developed to a high specification and thoroughly
tested, they cannot be totally guaranteed to be free of errors. Thus this instrument, or part of the
instrument, must not be used to influence a control system from which risk to life or property can
arise directly or indirectly, without additional protection. Maintenance and repair work must
only be performed by trained, competent, technical personnel familiar with the associated risks.
•
The instrument has 2 measurement inputs connected in parallel; only one of these inputs must be
used at any one time. No leads must be plugged into the unused connector for safety reasons.
The unused circular socket must be covered with the cap supplied.
•
Before starting any measurement, make sure that the device under test does not carry an external
voltage (e.g. mains voltage, voltage generated by a rotating motor etc.)
•
Take care when handling inductive devices under test. By the physical nature of these devices,
life-threatening induction voltages can be generated when the test current is disconnected. Read
the instructions in the “Load selection” section.
•
To avoid electric shock, never open the case. The instrument contains no components that can
be maintained, adjusted or calibrated by the customer. The instrument can operate with all
standard mains voltages in the world without needing to be switched over.
•
Always replace fuses with fuses of the same type. Never use fuses with different characteristics
or other related currents. Before changing the fuse, pull out the mains plug and short-circuit the
device under test.
•
Should foreign bodies or liquids get inside the unit, disconnect the main lead. Get the instrument
checked over by qualified technical personnel before using it again.
•
Always leave repair work to qualified technical personnel.
•
If you do not intend using the instrument for a prolonged period, take the mains plug out of the
socket. Always pull on the connector itself, never the cable.
•
Should liquid from a broken display escape from the unit and get on your hands, wash your
hands thoroughly using soap and water. Remove any residues of the liquid with acetone or
ethanol.
•
Always keep the instrument out of rain or away from moisture to prevent a fire hazard or the risk
of electric shock.
•
Check the mains lead before use.
