Thermostats must not be connected to any other
voltage sources during test.
About insertion tubes, insulation plugs, well and
sensor:
Never leave hot insertion tubes which have been
removed from the calibrator unsupervised – they may
constitute a fire hazard or personal injury.
If you intend to store the calibrator in the optional
carrying case after use, you must ensure that the
instrument has cooled down to a temperature
below 100°C/212°F before placing it in the carrying
case.
Never place a hot insertion tube in the optional carrying
case.
About the fuses:
The fuse box must not be removed from the power
control switch until the mains cable has been
disconnected.
The two main fuses must have the specified current
and voltage rating and be of the specified type. The
use of makeshift fuses and the short-circuiting of fuse
holders are prohibited and may cause a hazard.
About the liquid bath (RTC-158/250 A/B/C only):
For liquid bath ensure that the sensor is absolutely
clean and dry as a few drops of water in the well (liquid
baths) might cause a steam explosion.
Do not pour cold fluid into a hot well – it might cause
an explosion.
AMETEK Denmark A/S does not take any
responsibility, if the well is filled with other fluids than
those recommended.
Liquid baths should only be operated by trained
personal.
Heat transfer fluids must only be used in calibrators
prepared as a liquid bath. If these fluids are heated
above specified temperature they will create noxious or
