5. Factors affecting
calibration and accuracy
In order to get the maximum accuracy from the
equipment and to ensure accurate calibration the
factors listed below should be considered as they
will all affect performance.
1. The base of the blocks and the heated surface
in the unit must be scrupulously clean to
ensure good contact.
2. The blocks should be pushed firmly together
to the right hand side of the recess
3. The thermal radiation from the blocks can be
affected by surface condition and affect
accuracy. The top surface should be kept
clean and shiny.
4. If the unit is used in an area of strong drafts
such as inside a fume hood there can be a
temperature gradient across the blocks. In
this case the safety cover should be used to
protect the blocks from the air flow.
5. During calibration the temperature probe used
should be a good fit in the hole in the block.
6. Removal of aluminium
blocks
N.B. Do not attempt to remove blocks until
the instrument has been switched off and
allowed to cool
The instrument is supplied with a special tool to
facilitate removal of the blocks.
This should be screwed into the thermometer
hole in the top of the block and then used to lift
the block clear of the instrument. An extension
piece is provided for use with long tubes.
There is a convenient storage groove located on
either side of the body casing – see figure 1.
7. Aluminium blocks and
accessories
The following range of aluminium blocks is
available. All are manufactured from anodized
aluminium and have an extra hole designed to
accommodate a thermometer if desired.
All blocks have dimensions (w x d x h) of 75 x 95
x 50mm and can be used in any combination.
