SAFETY WARNINGS

The following safety information must be observed to insure

maximum personal safety during the operation at this meter:

·

Measurements beyond the maximum selected range

must not

be attempted.

·

Extreme care

must

be taken when measuring above 50 V, especially on live bus-bars.

·

To measure voltage, the instrument must

not

be switched to a current or resistance range,

or to the diode check or buzzer position.

·

Circuits

must

be de-energised and isolated before carrying out resistance tests.

·

The rotary selector switch must only be turned

after

removing test connections.

·

All external voltages

must

be disconnected from the instrument before removing the

battery.

·

Test leads and prods

must

be in good order, clean, and with no broken or cracked

insulation.
