Setting bath temperature
WARNING Prior to setting the bath temperature, ensure that the reference thermo-
meter in the bath is suitable for the desired temperature range. If not,
remove thermometer from the bath. If the bath temperature rises above

meters pose particular problems, since mercury from a damaged
thermo-meter may circulate with bath fluid.
