5. MAINTENANCE
Normally no maintenance is required other than cleaning with a moist cloth. Avoid aggressive detergents or solvents.
CAUTION:
Before any maintenance, repair or exchange of parts or fuses, the instrument must be disconnected from
the mains supply and all power sources. In the event of a fault occurring, the instrument should be returned
to our factory or agent. A mains fuse is fitted to the mains inlet socket on the front panel, and should be
replaced if necessary.
CAUTION:
Disconnect mains lead and all connecting leads, before removing fuse holder. Replace only with the correct
fuse type, i.ee according to the following chart.
6. BATTERY CHARGING
The 5867 has built-in rechargeable sealed lead acid batteries which are fully charged when delivered. To indicate the
state of charge, 8 LED’s indicate the remaining battery capacity in % of full charge.
The battery charger is built-in and the instrument may be connected to a voltage supply of between 90 to 260V AC. The
instrument may be operated with a flat battery, provided that the unit is powered to the mains – in this way the unit can be
simultaneously operated and charged. If the unit is switched on and the battery is not sufficiently charged, the unit will
turn itself off automatically. To conserve the battery, if no key is pressed during a 20 minute period the unit will also switch
itself off. To protect the battery from complete discharge below a minimum capacity the unit will self power off.
Charging is automatically controlled with built-in protection circuits eliminating the possibility of over charging.
The unit will be fully recharged in 8 hours without being used at the same time.
A fully charged unit should allow continuous operation for a working day, without the need to connect to the mains.
BATTERIES
The internal batteries are a sealed lead acid type. Care should be taken when disposing of them and they may be
returned to Tinsley for safe disposal.
