Infinite setting

The mechanical zero of galvanometer must be periodically checked. In order perform this checking, be sure that the insulation
tester is off. The pointer should stay on the right end of the scale just over the infinite mark on scale C. In other case, the
plastic screw at the bottom of the galvanometer acrylic cover shall be adjusted.

Replacement fuse

Para substituir el fusible debe utilizarse un destornillador de pequeño porte, y girar la tapa del portafusible ) aproximada-
mente un cuarto de vuelta en sentido antihorario, hasta sentir que está destrabado y que el resorte interno empuja hacia
afuera al fusible. Luego de verificar si el mismo está abierto puede substituirse por otro de idénticas características.
Fuse Schurter, model SPT 5 X 20 (Time-lag) 2A/ 250V. High breaking capacity H.

Cleaning

Cleaning of this instrument should be carried out using a soft cleaning anti-static liquid, after verifying that it doesn't affect the
plastic parts used in the case and in the Control Panel of this equipment.
