Replacing the Instrument in its Housing
CAUTION:
Before replacing the instrument in it’s housing, ensure that all power has been
removed from the rear terminals.
With the required option modules correctly located into their respective positions the
instrument can be replaced into it’s housing as follows:
1. Hold the Power Supply and Input boards together.
2. Align the boards with the guides in the housing.
3. Slowly and firmly, push the instrument in position.
CAUTION:
Ensure that the instrument is correctly orientated. A mechanical stop will operate if
an attempt is made to insert the instrument in the wrong orientation, this stop MUST
NOT be over-ridden.
Auto Detection of Option Modules
The instrument automatically detects which option modules have been fitted into each slot.
The menus and screens change to reflect the options compatible with the hardware fitted.
The modules fitted can be viewed in the products information menu, as detailed in the
Product Information Mode section of this manual.
Replacement of Power Supply or Input Boards
It is recommend that users change these boards only if unavoidable.
1. Remove the instrument from it’s housing as detailed above.
2. Remove all option modules.
3. Replace the Power Supply or Input board as required. Carefully observe the transformer
colour and the case labelling to check the supply voltage when replacing the power
supply board.
4. Reassemble the unit in it’s case.
5. If the input board has to be replaced, a full recalibration must be carried out before the
instrument is used. Refer to the calibration section of this manual for instructions.
CAUTION:
Replacement of boards must be carried out by a trained technician.
If the Power Supply board does not match the labelling, users may apply incorrect
voltage resulting in irreparable damage.
