13.3 Fuses
Application of high energy pulse during Insulation resistance
measurement or application of voltage during Continuity and Ohm
measurement will blow the fuse. If the fuse blows, eliminate the cause of
the overload before placing the instrument back in to operation !
Fuse Testing
* Set the function selector switch to any insulation measurement range.
* Open circuit the test leads.
* Press the “Test” button until “OL” or “FUSE” appears on display.
If display = “OL” : Fuse is OK.
If display = “FUSE” : Fuse is blown and needs replacement.
Note : Once “FUSE” is displayed all the functions are inhibited.
Immediately switch the Instrument OFF and replace the fuse.
Replacement of Fuses
* Open the instrument as described under battery replacement.
* Remove the defective fuse and replace it with a new fuse.
* Make sure that the new fuse makes good contact.
Specification :
Current Rating : 500 mA / 500V-6.3 mm x 32 mm with a breaking capacity
of 10kA.
Recommended fuse manufacturer : Siba
Part No. : 70-065-63/0.5A
Be absolutely sure that only the specified fuses are used !
The use of a fuse with different triggering characteristics,
a different nominal current or a different breaking capacity
exposes the operator, the system and the measuring
instrument to danger. The use of repaired fuses or short-
circuiting of the fuse holder is prohibited.
13.4 Housing
No special maintenance is required for the housing. Excessive
contamination has an adverse effect on isolation and reduces input
resistance. The surface must be kept clean for this reason. Use a slightly
dampened cloth for cleaning. Oil free petrol is recommended for
cleaning. Avoid the use cleansers, abrasives or solvents.

13 Maintenance
Attention !
Disconnect the instrument from the measuring circuit before
opening the instrument to replace the battery or the fuse !
13.1 Battery
Before initial Start-up, or after long storage of your instrument, make sure
that no leakage has occurred at the instrument battery. Repeat this
inspection at regular intervals.
Battery symbol “ ” appears on the LCD in either of below conditions :
1. Battery voltage is <5.4 V. Battery replacement (recharging in case of
rechargeable battery) is necessary.
2. For a specific range depending on application
In either of above condition when the battery symbol is displayed, no
measurement can be done, and the battery symbol flashes.
Replacing the Batteries
* Lay the instrument on to its face, loosen the two screws at the rare
panel and lift out the housing base, starting at the bottom (a). The
housing base and the housing top are held together with snap hooks
at the top of the front panel.
* Remove all the cells from the battery holder and replace them with
new ones.
* Important for reassembly : first lay the housing base into place such
as shown in diagram below. Push the housing base and housing
top together, first at the bottom front (a) and then at the top front (b).
* Retighten the housing base with the two screws.
* Please dispose of the used cells properly.
13.2 Operation with Mains Adapter (Optional)
Use only Mains Adapter (Output : 12VDC, 1000mA) to power ON the
instrument.
During power supply via mains adapter in inserted batteries are cut off
electronically and thus can be left inside the instrument.
Note : There is no need of internal batteries when AC-DC Adapter
is connected to the instruments.
If re-chargeable batteries are used they must be charged outside
the instrument.
