The standard nozzles can be removed to enable other adapters or connectors to be fitted. When the nozzle is removed, the gas inlet has an 1/8th inch British Standard Parallel (BSP) thread. It is important that any other connectors used here have exactly the
same thread.
2.1.5 Mains Supply
Warning. The monitor must be used with protective earthing.
The monitor operates in the AC voltage range from 85 – 264V on a single phase supply, 50 Hz – 60 Hz.
The power cable is connected to a socket on the rear panel. The on-off switch is located
immediately above this socket.
2.1.6 Checking and Changing the Fuses
On delivery, two 20 mm T1.6 A slow-blow fuses are installed in the monitor – one in
the live and one in the neutral mains feed. If you want the monitor to conform to CSAapproved standards, you must use the additional fuse holders (JS 0075) supplied with
the instrument, but using 32 mm T1.6 A slow-blow fuses instead. When replacing fuses
always ensure that the correct fuses are used.
To check and change the fuses:
1. Remove the power cable from the mains socket.
2. Insert a small screwdriver under the top edge of the plate covering this socket
and use it to lever the plate downwards. See Fig.2.3.
Note: The cover cannot be removed when the power cable is connected to the monitor.
