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. Neither too hot nor too cool 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 an 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.
