ADDITIONAL INFORMATION

USER MAINTENANCE

Before cleaning your unit, disconnect it from the power supply. The outer case of the TC-PLUS may

be cleaned with a cloth dipped in water or ethanol (hexane or 50% methanol can also be used). No

part of the case or cover should be immersed in the solvents. Do not use aggressive solvents such

as acetone or abrasive cleaners. The block may be wiped with water, ethanol or propan-2-ol and

may be decontaminated by wiping with 2% Neutracon or 1% bleach solution.

Before using any cleaning or decontamination method except those recommended here, the

responsible person should check with Techne that the proposed method will not damage the

equipment.

FAULT FINDING

Note that this equipment should only be dismantled by properly trained personnel. Removing the

outer cover exposes potentially lethal mains voltages. There are no user serviceable parts within this

equipment.

Should you have any problems with your TC-PLUS which cannot be easily remedied, you should

contact your supplier and return the unit if necessary. Please include details of the fault observed and

remember to return the unit in its original packing. Bibby Scientific Ltd. accepts no responsibility for

damage to units which are not properly packed for shipping: if in doubt, contact your supplier, giving

the full serial number of the unit.

FUSES

If the display on the front panel is not lit, one of the two fuses may have blown. Check that there is no

external cause, such as a faulty plug or lead. Check both fuses and replace the faulty fuse with a

new one of the correct value (fuse values are given on the label next to the power inlet). Note that

fuses should only be replaced by a qualified electrician.

The holder for the two fuses is built into the mains input socket. First remove the power cable and

then gently prise the fuse drawer open with a flat-bladed screwdriver or similar tool. Each fuse can be

removed by using the screwdriver as a lever.

Exchange the faulty fuse in the fuse holder for a working fuse of the correct value. Finally, replace

the fuse drawer in the fuse compartment and push the drawer shut. Fuses which blow repeatedly

indicate a serious fault and you should return the unit to your supplier for repair.

INSULATION TESTING

This equipment is fitted with RFI suppression circuitry. Any check of the electrical insulation by

means of high voltage dielectric testing (for example as in BS EN 61010-1) must be carried out using

only a DC voltage.

This unit contains semiconductor components which may be damaged by electric field effects.
