Fuses
Two fuses are located at the back of the instrument below the
main power receptacle. To replace a blown fuse, disconnect the
detector from the power supply, and replace the fuses with ones
of the same type and rating as indicated on the back panel.
The fuses have a code marked on the cap (e.g. T3.15AH250V).
This refers to the fuse characteristic (‘T’ - time lag or ‘F’ - fast
acting), the current rating (‘x’ amperes), the breaking capacity
(‘H’ - heavy or ‘L’ - low) and the voltage rating (‘y’ volts). This
code must correspond to the code appearing next to the fuse
holders.
WARNING:
To prevent reduced safety protection or unwanted fusing, ALWAYS ensure that the
code on the fuse cap matches the information printed next to the fuse holders.
To check or replace a fuse:
1. Disconnect the detector from the mains power supply.
2. On the mains input connector (rear panel, refer to Figure 34),
expose the fuse compartment by using a small, flat blade
screwdriver to lift the fuse cap (refer to Figure 35). Then,
slide out the fuse holder (lower red section; refer to Figure
36). Both fuses are located inside on either side of the fuse
holder (refer to Figure 37).
