Most probes have handle temperature limits. Be sure that the probe handle tem perature
limit is not exceeded in the air above the instrument.
The instrument and any thermometer probes used with it are sensitive instru ments that
can be easily damaged. Always handle these devices with care. Do not allow them to
be dropped, struck, stressed, or overheated.
When calibrating PRTs always follow correct calibration procedure and cali brate
from high temperatures to low temperatures with the appropriate triple point of water
checks.
Components and heater lifetimes can be shortened by continuous high tempera ture
operation.
If a mains supply power fluctuation occurs, immediately turn off the bath. Power
bumps from brown-outs and black-outs can damage the instrument. Wait until the
power has stabilized before re-energizing the bath.
Fluids may expand at different rates. Allow for fluid expansion inside the well as
the instrument heats. Otherwise, the fluid may overflow the well and leak into the
instrument.
