voltmeter on all switch positions except ‘OFF’ and 

. In addition, the beeper

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. 

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.

E.M.C.

Meets EN 50081-1 and EN 50082-1 (1992).

Weight:

530g (including batteries)

dampened with soapy water or Isopropyl Alcohol 
(IPA).
