CHANGING LIQUIDS
If possible it is best to plan so that liquids do not need to be frequently changed. This may be achieved by liquid
choice, determining convenient calibration points or having more than one bath - each with a different liquid to cover
the routine calibration range.
To change the liquid,
1.
Disconnect from the supply.
2.
Ensure the liquid is at a safe handling temperature. Then open the drain tap.
3.
Drain the liquid into clean containers of adequate capacity, properly labelled for future use.
4.
Clean the bath. Detergent and absorbent paper will assist. If the bath has been used with oil it can be helpful
to re fill with water and detergent and to allow the mixture to circulate before draining again.
5.
Close the tap.
