Preparation of the meter for operation

Having purchased the meter examine completeness of the con-
tents of the package.
Before measurements commence, it is necessary to realise the
following actions:

Make sure the conditions of the batteries or accumulators per-
mit to realise measurements,

Make sure the casing of the meter and the insulation of the test
leads are not damaged,

Insert the black test lead into the negative COM terminal and
the red test lead into the other positive terminal,

ALWAYS turn the function switch to the OFF position when the
meter is not in use. This meter has Auto OFF that automatically
shuts the meter OFF if 30 minutes elapse between uses.
Connection of inappropriate or damaged test leads consti-
tutes a risk of an electric shock with a dangerous voltage.
On some low AC and DC voltage ranges, with the test leads
not connected to a device, the display may show a random,
changing reading. This is normal and is caused by the high-
input sensitivity. The reading will stabilize and give a proper
measurement when connected to a circuit.
