these tables enables this to be done quickly and easily. These
will guarantee that the value being measured is greater than or
less than the limit value specified as appropriate.

SAFETY
The instruments meet the requirements for double insulation to
IEC 1010-1 (1995), EN 61010-1(1995) to Category III*, 300V
phase to earth (ground) and 440V phase to phase, without the
need for separately fused test leads. If required, fused test
leads are available as an optional accessory.
* Relates to the transient over-voltages likely to be met in fixed
wiring installations.
Complies with the following parts of EN61557, Electrical safety
in low voltage systems up to 1000V a.c. and 1500V d.c. –
Equipment for testing, measuring or monitoring of protective
measures:-
Part 1 – General requirements
Part 2 – Insulation resistance
Part 4 – Resistance of earth connection and
equi-potential bonding
