will sound on all switch positions except ‘OFF‘ and
. All selected tests will be
inhibited except for Insulation tests, which will remain available until the voltage
exceeds 55 V. (
BM224
will beep and display a flashing ‘V’. Testing is inhibited).
Default Voltmeter Ranges: 25V - 450V a.c. 50/60 Hz ± 2% ±3 digits
450V - 600V a.c. 50/60 Hz ± 3%
d.c. - unspecified
Automatic Discharge: Capacitive circuits are automatically discharged
when the test button is released following an insulation test.
Power Supply:
6 x 1,5V cells IEC LR6 type only.
Battery life:
Typically 3000 x 5 second operations (worst
case, with
not selected).
Battery cells should not be left in an instrument which may remain unused for
extended periods of time.
Low Battery Indicator: The low battery indicator symbol
will appear
when the battery cells are exhausted.
Battery Replacement:
The rear cover must not be opened if the test
leads are connected. To remove the rear cover, release the screw at the
bottom of the cover and lift the cover upwards.To avoid the possibility of
shock, do not press the test button or touch the fuse when changing
batteries.
Fuse:
500 mA (F) H.B.C.10 kA min (32mm x 6mm)
To check this fuse, select M
Ω,
open circuit the test leads and press the test
button until a reading is obtained. Display of the fuse symbol
or an error
code indicates a ruptured fuse. Located behind the rear cover, this fuse can
be replaced by the user. The rear cover must not be opened if test leads are
connected. The replacement fuse must be of the correct type and rating. To
avoid the possibility of shock, disconnect the battery before touching the fuse.
Safety: The instruments meet the requirements for double insulation to IEC
1010-1 (1995) EN 61010-1 (1995) to Category
III
*, 300 Volts phase to earth,
440 Volts phase to phase, without the need for separately fused test leads.
*Relates to transient overvoltage likely to be found in fixed installation wiring.
