DURING USE

- Never exceed the limit protection values indicated in the
specifications of each type of measurement.
- When the multimeter is assigned to one type of measurement,
do not touch the terminals not in use.
- Never use the multimeter to measure voltages that might
be in excess of 600 V above the earth wire in category II
installations.
- When the level of values to be measured is unknown prior
to commencing measurement, place the level selector at the
highest position.
- Before turning the selector to change the functions, disconnect
the test cables form the circuit to be measured.
- When carrying out measurement on television or electronic
switch circuits, always remember that there could be high
range voltage pulse in the control points which could break the
meter.
- When working with voltages above 60V DC or 30C AC or rms,
keep your fingers behind the barriers while measuring.
- Before trying to insert transistors to be measured, always
make sure that the test cables have been disconnected from
any measurement circuit.
- Components must not be connected to an hFE socket when
carrying out voltage measurements with test cables.
- Never carry out resistance measurements on operating
circuits.
