Storage
-20°C to + 70°C
Temperature Coefficient: ±0,1% per °C
Power Supply:
Single 9V Alkaline battery I.E.C. 6 LR61 type
Current consumption:
110 mA max on Insulation
40mAmax on Resistance
220 mA max on 2
Ω
range
Battery life:
Not less than 1800, 5 second operations on 2
Ω
range.
Battery Condition Test:
The battery condition test position checks the
battery voltage on a simulated load, when the ‘Test’ push button is
pressed. The instrument pointer should deflect clockwise to within the
‘Battery Check’ arc on the scale. Remove the battery if the instrument is
not to be used for an extended period of time.
Battery Replacement:
For safety reasons, the battery compartment must not be opened if the
test leads are connected. To remove the battery cover, release the screw
in the centre of the cover and lever the cover upwards.
Replaceable Fuse:
500 mA, 250V. H.B.C. type (F) (20mm. x 5mm)
To check this fuse, open circuit the test leads, switch to the 200
range
and press the ‘Test’ push button. A reading of <200
Ω
indicates a ruptured
fuse. Located in the battery compartment, this fuse can be replaced by the
user. The replacement fuse must be of the correct type and rating.To
replace the fuse, disconnect the test leads, remove the battery cover by
releasing the screw in the centre of the cover and levering the cover
upwards. A spare fuse is clipped onto the battery cover.
Non Replaceable Fuse:
2A - 500 V H.B.C. type (F) 50 kA. Fitted for
overall safety protection, this fuse is not replaceable by the user. No
response from the instrument to an insulation test, with the leads shorted
together is likely to mean that this fuse has ruptured. The instrument must
be returned to the manufacturer, or an approved agent for repair.
Safety:
Meets the requirements for double insulation to IEC1010-1
