Power Supply
Battery Type:
6x1,5V Alkaline cells IEC LR6 type
Battery Life:
Typically Up to 4000 5-second tests.
Auto Shut Off
The BMM500 series feature a
selectable auto shut off facility which
turns the instrument off after
approximately 5 minutes, (12minutes
for insulation ranges), to conserve
battery life. This can be extended by
the user to 60 minutes.
Safety
The BMM500 series complies with
the latest international directives
concerning safety and
electromagnetic compatibility.
The instruments meet the
requirements for double insulation to
IEC 61010-1 (1995), EN 61010-1
(1995) Safety Requirements for
electrical equipment for measurement,
control, and laboratory use. Category
III**, 300 Volts phase to earth
(ground) and 440 Volts 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
EN 61557, Electrical safety in low
voltage systems up to
1000 V a.c. and 1500 V 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
Part 10 - Combined Measuring
Equipment
