Maintenance & Calibration; Remote Operation - TTI 1604 Manuel D'instructions

Routine maintenance is limited to re-calibration and cleaning. The only repair maintenance that
can be carried out by the user is current range fuse replacement.
Calibration
Calibration is guaranteed as in the specification. The manufacturers provide a re-calibration
service, as do most of their agents overseas. Where owners wish to carry out re-calibration
themselves, this should only be done by skilled personnel with access to precision equipment
working in conjunction with the service manual which may be purchased directly from the
manufacturers or their agents overseas.
Current Range Fuses
The mA socket is protected by a 1A (F) HBC fuse and the 10A socket by a 10A (F) HBC fuse,
both mounted internally. To replace a fuse, proceed as follows:
1. Disconnect the instrument from all voltage sources.
2. Remove the 4 screws from the underside and lift off the case upper.
3. Replace the fuse with one of an identical rating using the diagram below as a guide.
4. Reassemble in the reverse order.
Mains Fuse
The transformer primary is protected by an integral thermal fuse which is not user replaceable.
Should a fault develop which causes the thermal fuse to blow, the meter must be returned to the
manufacturer or agent for service.
The RS232 interface permits remote control and data-logging to disk using optional Windows
software; operation is controlled by clicking with the mouse on the keys of the virtual front panel
displayed on the PC.
Connection between the RS232 port and the PC's serial port is made using a 9-way D-type to
D-type cable with all connections made, see Connections section under General Operation.
